Tastes Like Chicken

I’m sorry for the lack of posts this year. It’s been a bit of a rough year, and, long story short, I’m now in a one-year master’s program to become a high-school Biology teacher. This came with 17 graduate credits this summer, so I’ve been a bit swamped. However, I have been able to get to the Akron Zoo every once in a while. There, I saw an animal that was perfect to pull EUT out of its eight-month slump. Meet the Mountain Chicken.

No, that’s the correct picture. Leptodactylus fallax also goes by Giant Ditch Frog or Crapaud (French for “toad). It is an impressively large frog¹, weighing in at eight inches long and 1 and a half pounds. It hails from a few Caribbean islands, namely Dominica and Montserrat.

With a common name like “Mountain Chicken,” it isn’t really difficult to understand the main reason this animal is endangered: it’s delicious. Other problems like habitat destruction and the Cytrid fungus that have ravaged all amphibian populations are also plaguing this regal animal².

As conservation programs tried to raise young froglets to maintain the population, they had to figure out the strange breeding and rearing habits of the Mountain Chicken. First, they don’t breed in water like other frogs. Instead, they dig burrows that fill with rainwater and do their business there. In this underground pool, the female releases a liquid that the male whips into a foamy nest. Then things get weird.

The above video gives a wonderful description of Mountain Chicken childcare, but I’ll give you a synopsis. Rather than resorting to grazing, hunting, or cannibalism like other tadpoles, the Mountain Chicken tadpoles rely on mom, who spews forth tens of thousands of unfertilized eggs. These are quickly gobbled up by the little babies, and the feeding frenzy is an image you’ll try to scrub from your mind for days.

Recently, hunting the Mountain Chicken has been outlawed. Scientists are still working on curing amphibians of the Chytrid fungus. Hopefully these, along with those breeding programs, can bring this Chicken back from the brink.

  
¹The Mountain Chicken is only about half the size of the Goliath Frog, but that’s still pretty hefty.
²When held, they make an alarm call that sounds exactly like a giant squeaky toy. It’s ear-shatteringly adorable.

They Call Him Flipper

Dolphins are charismatic, no question about that. They play, they learn, they do amazing acrobatics. Their smiling faces draw people to aquatic parks worldwide. The freshwater dolphins have gotten some press lately, but they aren’t the prettiest dolphins around.

I suppose the Gharial-like snout on the Ganges River Dolphin (Platanista gangetica) is what bothers me about it. Its stubby dorsal fin gives it a humpbacked appearance that is far less pleasing than the torpedo-shaped marine dolphins we’re used to. However, both of these serve an important purpose: maneuverability. The shorter dorsal fin allows for faster turns, and the thin, tooth-filled rostrum is perfect for slashing sideways into an unsuspecting fish.

The Ganges River Dolphin is also effectively blind. The lack of a lens means that any light entering the eye is only seen as unfocused blurs of shadow. However, for a creature with echolocation living in the silt-filled rivers of India, this is less of a problem than one would expect.

As those silt-filled rivers are in some of the most densely human populated areas of the world, you can expect there to be some environmental issues. Damming, pollution, boat traffic, and by-catch are all problems that this blind dolphin faces. The Yangtze River Dolphin faced similar problems, and is now listed as “functionally extinct”.

The Ganges River Dolphin may have some support to save it from that fate. Dolphin reserves are being established, and the WWF is trying its darndest to educate the public. India even named this dolphin the National Aquatic Animal. However, there is still a lot of work to be done to make sure it doesn’t go the way of the Yangtze River Dolphin.

Nevermore

Crows have been long associated with death in Western culture. In Medieval times, they were known to follow armored soldiers into battle for the prospect of feasting on the casualties. In modern times, people see them eating roadkill, as Halloween decorations, or as the monsters from The Birds. While Crows certainly enjoy carrion there is another side to them less frequently seen in modern interpretations. For one thing, they are omnivorous so dead things are only part of their diet. For another thing, they might be just as smart as the prettier parrots.

Our main method of determining animal intelligence is looking at how well they solve problems. Crows are masters. They bend wires into fishhooks to pull food from thin tubes. They have learned to use cars to crack hard nuts—while waiting for the light to turn red to retrieve them. One person is trying to teach them to use a vending machine. They can mimic human speech, with more clarity than most parrots. So, when you see a Crow walking down the sidewalk, don’t think, “portent of death,” think “Whosa prettybird?”

















The Hawaiian Crow (Corvus hawaiiansis), is locally known as the ‘Alala. It has a lot in common with your more familiar American Crow: they eat whatever they want (mostly fruit and eggs), they hang out in groups, are strong fliers, and like to play wrestle. They use tools to get to their food. However, the ‘Alala is larger, and has a larger, rounder beak.

Why the Hawaiian Crow is in trouble is up for debate: it could be disease, habitat loss, or introduced predators, such as rats or mongooses. Chances are good that it’s all of the above. There is no question that it is in big trouble. The last wild ‘Alala pair were seen in 2003. All the rest of them alive today—about 70 individuals—are in two captive breeding facilities. Release programs have been unsuccessful. Part of that is due to the aforementioned predators, but there’s a problem that the conservationists didn’t foresee. Crows are smart, but because of that, they need to be taught. Without a whole society to teach them, the new crows haven’t learned how to properly forage or escape predators.

Plague of Locusts

I’m sorry I missed the end of August, but I was kind of getting married, so I hope you’ll excuse the late post. Since I just moved to the Upper Peninsula of Michigan¹, I decided I needed to write about a local Endangered Ugly Thing. Meet the Lake Huron Locust (Trimerotropis huroniana)












This locust is a drab-looking grasshopper, and not one to stand out in a crowd. It’s about an inch long, slate grey, and looks like a large number of related insects. The biggest characteristic that sets them apart from other grasshoppers is their habitat. Instead of living in thick grasses or dense woodlands, they live on meagerly vegetated beaches. There, they blend in with the sand and eat the sparse grasses that grow there.

Like most grasshoppers, male Lake Huron Locusts use the familiar melodic (or grating, depending on your preference) chirping to attract a mate. They also add an aerial element to their ritual, flying up in the air, snapping their wings to make a crackling noise². Eggs laid in the summer hatch the next spring, and mature in time to start the cycle again.

One of the largest threats to the Lake Huron Locust is the creation of summer homes on the dune habitats where these insects reside. This irks me, as the “summer” here lasts approximately from mid-July to mid-August. Protecting the dunes and the vegetation found there is the most effective method to keep these little locusts alive.

¹This is properly pronounced “da U.P., eh?”
²Does it surprise you to know that entomologists have a name for this? It’s called “crepitating”.

Black and White and Red All Over

This marks the 100th post on this blog. To celebrate, I intend to do something a little different from what I’ve done in the past. For this month’s species, I’ll be writing about an animal widely considered to be one of the cutest around. It has become China’s golden child and the face of the World Wildlife fund. I am, of course, talking about the Giant Panda (Ailuropoda melanoleuca). While previously thought to be halfway between bears and raccoons, recent evidence puts them squarely in the bear family. Keep that in mind as you read this, as there is a depth to these animals that isn’t widely publicized.




The idea that Pandas eat only bamboo isn’t too far from the truth, as it makes up the large majority of their diet¹. However, they are not above enjoying carrion if they happen to come across it. This is beautifully illustrated in this ARKive video, where a Panda saunters up to a rotting deer carcass, rips off a leg, and sits back to enjoy his meal. There are even reports of a wild Panda killing sheep, though it didn’t eat any of them.

Carnivory is one thing, but surely aggression isn’t a trait of these cute fuzzy-wuzzys, right? I’m sure that’s what went through mind of the drunk man who jumped into a zoo enclosure to give Gu Gu the Panda a hug, right before Gu Gu bit his legs. Or the teenager that scared Gu Gu into biting his legs. Or the man who jumped into Gu Gu’s enclosure to retrieve his 5-year old’s toy. Guess what happened to him. “Not so Cute” or “Not too Cuddly” seems to be the response of reporters on incidents like these. How surprised would we be if these had occurred with a Grizzly Bear? This is just an increasingly frustrated animal trying to defend its territory. The story is likely the same for the Panda in this video, attacking a man sitting outside its enclosure.

While it may seem like I’m trying to vilify the Panda, it's only to prove a point. I’ve got nothing against scavengers, or even dangerous animals. But the Giant Panda just dropped a few levels in the cuteness scale in the last two paragraphs, didn’t it? I’ve got all sorts of tidbits that could make any Charismatic Megafauna seem less charismatic². Putting an animal on a pedestal just makes it that much easier to knock off, and turning an animal into a symbol makes you forget that it’s an animal. All creatures have behaviors that humans aren’t fond of, but we can’t expect them to act like giant teddy bears. While conservation efforts have helped the Giant Panda in the wild, over-exposure of the “cute” version of their life has left more and more people bored by its plight. The solution, as I see it, is to spread the exposure around to any other species that could use the help. Which is where I come in, I suppose. I hope I’ve managed to achieve that since I started this blog.

I really want to thank all of my readers who have stuck with me through these one hundred posts. I also have to thank my fiancée and my parents, who have helped with editing and ideas, but far more importantly have completely and utterly supported this fool idea of mine for four years. Thank you.

¹ All bears are omnivorous, but the meat to veggie ratio depends mostly on the availability of the food.
²For example, Gorillas and Lions will commonly kill the young of competing males. Chimpanzees and Dolphins commit murder of their own species. Black Rhinoceroses have the highest rates of death from fighting each other than any other animal. I could go on.

Night on Bald Mountain

My fiancée has had a deep-seated dislike of non-human primates for a long time. So when she told me to look at this ugly monkey she saw on the ARKive front page, I was doubtful of its ugliness. I was wrong. It looks like the gremlins from, well, Gremlins (Use this picture for comparison).
















The Brazilian Bare-Faced Tamarin, or Pied Tamarin (Saguinus bicolor), is unsurprisingly found in the Amazon basin in Brazil. Like most tamarins, it spends its time avoiding predators and eating fruits, tree sap, and small animals. They live in small groups, with between four and fifteen individuals.

Their group structure is a reverse harem—the alpha female gets to mate with whatever male she likes. Most tamarins give birth to twins, and the Pied Tamarin is no different. Dad takes care of most of the child rearing (other than nursing, of course), with the other subordinates helping out. The whole group sleeps in one big pile, which I’m sure would be adorable if their faces didn’t look like gargoyles’.

There is one main unanswered question I have about the Bare-Faced Tamarin—why is it bare-faced? What purpose does a hairless face serve? It’s not like these guys bury their head in carcasses, like storks and vultures. My guess, which is only a guess, is that it may have something to do with keeping their head free of parasites. The problem with this theory is that they groom each other, meaning that other members of their group should be able to help with the nit picking.

As far as their status is concerned, the Pied Tamarin isn’t doing so well. They are considered one of the most endangered Amazonian primates due to their small, fragmented range coupled with the constant rainforest destruction we’ve all been hearing about for the last decade. Primate conservation programs, as well as captive breeding programs are working on keeping this goblin-faced monkey around.

Look Out For Mr. Stork

I’ve wanted to write about the Marabou Stork for a long time. It is amazingly ugly. It has a bald head, except for minimal scraggly hair. The giant, pointed beak, perfect for ripping into large African carrion, is the color of decaying bone. There is only one reason that it hasn’t appeared on this blog yet: it’s not endangered. Amrita from Not Extinct Yet has saved me though. No, she didn’t go and shoot enough Marabou Storks to put them on the list¹. She found the Greater Adjutant (Leptoptilos dubius) which is closely related enough the Marabou Stork to fill its place on Endangered Ugly Things.

Image from MangoVerde

The Greater Adjutant hails from Southeast Asia, roosting near wetlands that teem with its prey. What kind of prey? Whatever it can catch. Insects, crustaceans, frogs, fish, carrion, rodents, even slow ducks. Much like the Marabou Stork (and the vultures they compete with), the ugly bald head is a great adaptation for shoving one's face deep inside a rotting carcass².

Their large nesting colonies form in leafless trees around these wetlands during the dry season. As the water recedes, the aquatic animals this stork preys on are that much easier to grab. The Greater Adjutant uses this abundant resource to produce their eggs, and feed their hatchlings. I can't find any pictures of young Adjutants, but they can't be any uglier than the adults. Come the rainy season, they migrate to other wetlands in Northern India until the next breeding season.

The draining, clearing, and general messing-around-with of wetlands in the area has left only two breeding populations of these giant birds. One is in Cambodia, the other in Assam, India. Between these two areas, there are less than one thousand individuals. Along with the destruction of their habitat, the eggs and adults are also hunted, presumably because there's a lot of meat on a four-foot tall bird.

The Greater Adjutant is protected in the areas in which it's found, but enforcement is not always up to snuff. It seems that there was a big push to stop egg collection, which helped increase Adjutant numbers the next year. Hopefully these conservation efforts will continue to keep these magnificent, if horribly ugly, birds around.



¹ I’m imagining the IUCN listing—Threats: Conservationists.
²Think about eating a bowl of jello without your hands. Wouldn't that be so much more pleasant if you were bald?

How I Felt

Much like last month, August's EUT is a suggestion that came in a while ago, and I'm only just getting around to it. This is the first time that a researcher has suggested their own species of interest as an Endangered Ugly Thing, and I'm quite excited about it. He's even set up a support group for Ugly Thing researchers on the forum. Randy, the researcher, even had a professor tell him--in the middle of a presentation, no less--that his research topic was, "the ugliest thing I have ever seen - it looks like black vomit!" Now, isn't that just mean? Doesn't his research demand respect, regardless of how the species looks? On the other hand, it does look like black vomit.

Image by Randy Skinner

The Boreal Felt Lichen (Erioderma pedicellatum) is, according to ARKive, "known as the Panda Bear of lichens," due to its rarity. I personally think, given the professor's description, the lichen needs quite a bit more charisma before it can be described as the Panda Bear of anything¹. Much like the Rock Gnome Lichen, the Boreal Felt Lichen is actually two species living together in symbiosis. The majority of the Lichen is a fungus, which serves as structure and protection for the cyanobacteria that allows the organism to photosynthesize.

This lichen is quite picky about where it plants itself. It requires very large amounts of moisture, so it only lives in coastal areas. In Scandinavia it grows mostly on Norway Spruce, and in Newfoundland it keeps mainly to Balsam Firs. The only problem with the previous statement is that it might not exist in Scandinavia anymore. The Canadian population is under massive amounts of protection to save the 10,000 or so individuals that remain.

What has been hitting the Boreal Felt Lichen so hard, as to cause it to go extinct in much of its range? Scientists aren't sure, but they've got a lot of good ideas, such as deforestation, climate change, acid rain, and air pollution. It's very likely that it's a combination of these factors, as the cyanobacteria that provides the lichen with food is very susceptible to changes in humidity and pH.

The areas in Newfoundland that contain the majority of the remaining population are being protected by the government as soon as they find them. This is where our poor lichen researcher, Randy, comes in. He is using state-of-the-art landscape ecology to create models that would be able to predict where a previously unknown group of Boreal Felt Lichens might be found.

¹Maybe we should reverse it. How do you think Panda researchers would respond to their species being called "the Boreal Felt Lichen of Carnivora"?

Song of the Shrimp

New visitors from the Scientific American article: Welcome! I hope you find some things that interest you here. My forum is starting to pick up, and I would love to see some new blood there. Bryan, who I met at the Green Futures expo, I hope you can forgive me for not writing about the animal you suggested, but I completely forgot. For two months. Sorry.

Image from Ann Dickinson

This is the California Freshwater Shrimp (Syncaris pacifica). It doesn't look like much, which is actually a anti-predatory device, as its translucency helps hide it from predators. If hiding doesn't work, it has a protective spine useful for jabbing into a predatory fish's mouth.

These shrimp are only found in a few counties in the Bay Area in California, and seem to be fairly picky about their habitat. They live in the runs¹ of streams that have undercut banks, exposed roots, and overhanging vegetation. All of these features provide the Freshwater Shrimp with numerous hiding places.

The problem comes when those hiding places are disturbed. There are quite a few ways this can happen, all of which have the final result of removing the vegetation that these shrimp call home. The trees that provide the overhanging roots are removed when a stream is channelized, and agriculture and livestock fill the stream with runoff that buries those roots in silt.

There is quite a bit of good news going for the California Freshwater Shrimp. For one thing, its numbers appear to have almost quadrupled between 1991 and 2000. Another thing is that a number of teachers and students are using this as their rallying species to help teach people about freshwater habitat, and saving some endangered species in the process. If anyone in those programs reads this: I salute you. You will be able to tell future generations that you helped save a living thing from extinction.

¹Runs are the areas in streams halfway between the shallow, fast moving riffles, and the slow, deep pools. This site explains these quite well.

Perfect Past Tense - Earwig

If you are visiting through the Washington Post article: Welcome! I hope you stick around, look through my old posts, and leave some comments. If you’ve got any suggestions for animals to write about, I’d be glad to hear them. I’ve even got a forum here. As for my old readers (all six of you), I’ve got a nice, juicy insect for this month.

Image from Earwig Research Centre

Meet the Saint Helena Earwig (Labidura herculeana), the largest earwig in the world. It lives (lived?) on Saint Helena¹, a small volcanic island in the South Atlantic. Much like Attenborough’s Echidna, this specimen in the picture is not cavorting around its tropical island home, and for much the same reason: this species might have gone extinct in the ‘60s.

While most earwigs will eat about anything they can get their mandibles on, the Saint Helena Earwig is probably mostly herbivorous. They seem to spend most of their time in burrows, coming out only during nights after it has rained. This withdrawn behavior probably has not helped the people who are trying to determine if, in fact, it has gone extinct.

Though, it is not as if people have stopped looking. There have been a number of expeditions over the years, mostly led and funded by the London Zoo. From what I’ve seen, The Independent has been incredulous, if supportive, of spending thousands of pounds for people to wander around a tropical island looking for earwigs.

Most of the island of Saint Helena seems to be in ecological peril, and long time readers of this blog will understand when I say: “It’s because it’s an island.” Remote islands have a very specific ecology that is easily thrown off balance. Then, humans show up bringing rats, pigs, cats, dogs, and deforestation, wrecking the whole place. In the case of the Earwig, people seem to be blaming an introduced centipede, as well as the clearing of an area of forest.

Conservationists are worried about the Saint Helena Earwig, as well as other endemic arthropods. An airport, proposed in 2005, has not been built for fear of destroying the only habitat in which these gentle, albeit freaky-looking, giants may still survive.

¹Apparently named for the same saint as the volcano in Washington, though she doesn’t seem to have any direct connection to volcanoes.

Unsung- Helmet

It’s been a while since I’ve written about a bird. The problem with them is that they tend to be cute, pretty, or majestic. Except, of course, for the carrion-eaters, but I can’t just write about vultures and pretend I’ve covered the entire class. So, like I always do, I went trolling through ARKive’s bird section and found this beauty.

Image by Doug Janson

The Helmeted Hornbill (Rhinoplax vigil), hails from Southeast Asia, where it spends its time eating fruit, like the majority of Hornbills. They also hunt bugs, using their pointy beak in much the same way that a woodpecker would. This is not a small bird, growing up to around a five feet from beak to tail. Wikipedia describes their call as “hoots followed by maniacal laughter.” Listen to any of the recordings on this site all the way to the end, and you’ll understand what they mean.

The casque—the helmet that gives them their name—is solid, as opposed to most hornbills, which means the skull is about ten percent of the total body weight of the bird¹. This comes in handy, as the males participate in the aerial equivalent of Bighorn Sheep clashes, fighting over females and territory by running head-on into each other while flying. I can’t find any videos of this, but I’m sure it would be amazing.

Their headgear has also gotten them into some trouble. As it is solid keratin, it can be used as a reddish ivory-like substance for carving (called, surprisingly enough, hornbill ivory). As one can expect, this does not bode well for the bird. Well, it was all right when only the natives were doing it², but once the civilized world got wind of this material, things were not looking good. CITES has now clamped down on this, making any trade of hornbill ivory completely illegal. The constant rainforest destruction that everyone has worried about for as long as I can remember isn’t helping the Helmeted Hornbills’ population either.


¹Compare our atypically large head, with about 0.7 percent of our body weight.
²This tidbit isn’t entirely related, but I can’t think of anywhere else to put it: apparently the natives believe that a giant Helmeted Hornbill guarded the river between the land of the living and the land of the dead.

Velvet Revolver

I have been somewhat disappointed with the limited ability for back-and-forth communication on Blogger, so, at the suggestion of some of my colleagues at the Writing Center¹, I’ve started a forum on another site, which can be found here. Please visit it, and let’s start some fun discussions. This month’s EUT comes once again from ARKive, though I’m sure I had seen it in the past, and skipped over it due to lack of information. I think I’ve got enough to talk about this time around, so here is the Pink Velvet Worm

Image from ARKive

At a little more than an inch long, the Pink Velvet Worm (Opisthopatus roseus) looks something like a squishy centipede. However, it belongs to the phylum Onychophora, though most of the members look quite similar to the human eye. Velvet worms, as they are commonly called, are quite closely related to the Arthropods, though they lack the jointed legs that give the latter group its name. Instead, they have dumpy-looking caterpillar-esque legs with a pair of claws on the bottom of each.

All velvet worms are carnivorous, feeding on any invertebrate smaller than them. Much smaller prey are simply hunted down and eaten, but for larger prey, they have the coolest prey capture method: twin projectile glue guns concealed in their face, which they can fire up to ten times their body length. This glue is also useful for deterring predators, because no one wants that in their eyes.

Back to the Pink Velvet Worm itself. It has been found in a single forest in South Africa, and this forest has been logged heavily since the 1900s, both for the wood, as well as for plantations of non-native vegetation. These three factors—the small range, the logging, and the invasive species—have conspired to place the Pink Velvet Worm on the Critically Endangered list.

Conservation efforts are still in the works, of which listing is just one. They are putting together education efforts, which have worked in the past for other animals. Also, there are five Pink Velvet Worms in captivity, and hopefully we can learn more about what they do from these squishy little ambassadors to our race.

¹Yeah, I’ve been working at a Writing Center for about a year now. It’s made me a heck of a lot more confident with my writing. There’s no better way to learn something than by teaching someone else.

Velvety Underground

I’m sorry I missed February, but I started the in-depth work on my thesis, which makes it difficult to get into the blogging mindset. However, I have found another parasite that has managed to get listed¹. They live on the bodily fluids of a single species, rarely even seeing the light of day. After that description, I want you to imagine an orchid.
Now, look at this picture.

Image from ARKive

This is the Underground Orchid (Rhizanthella gardneri). While many orchids are parasitic—living as the botanical equivalent of a louse—they produce pretty flowers, so no one thinks twice about trying to save them. The Underground Orchid’s lifestyle is not much different, except for the fact that it looks like a root with a tumor. It lives in the root system of the Broom Honey Myrtle, a pine-like tree from Australia. This orchid produces no chlorophyll, because that would be pointless if the flower might break the surface. Instead, it gets its energy and nutrients from the Myrtle, but it’s not as simple as that. It never is.

I had originally thought that parasitic plants work by putting its roots into the roots of the host and effectively sucking the tree’s blood. Some do. The Underground Orchid, however, is myco-heterotrophic. This means that there is a fungus living in the Myrtle’s roots, sucking out its juices. The orchid then subsists on the juices of the fungus, making this some sort of strange nesting-doll version of parasitism². The end result is still the orchid parasitizing the tree, but with some (unwilling) help from a root fungus.

The Underground Orchid relies on the existence of the Broom Honey Myrtle, and tracts of these trees are being cleared to make way for agriculture. People are also attributing a decrease in health of the myrtle to a decrease in the numbers of the orchid. Preservation sites are being set up throughout the Underground Orchids’ range to help save them. Also, botanists are also working on finding a way to breed these root-flowers in captivity.

¹Just so you know, the Pygmy Hog-Sucking Louse managed to get a mention on QI.
²I’m sure there is some Australian burrowing insect that would suck the juices out of the orchid, making this even more recursive.

Come Sail Away

I'll be the first to admit that this month's EUT isn't all that ugly, but they can't all be eldritch abominations from the dawn of time. It does, however, look very dragon-like, though the color makes it look like it's straight out of a cartoon.

Image from SailfinDragon.com

This is the Philippine Sailfin Lizard (Hydrosaurus pustulatus). It lives up to its name well, with a tail that would not look out of place on a Dimetrodon¹. As one can guess from the scientific name, the Sailfin is not out of place in the water, using the sail to power its swimming through the rivers of the Philippine Islands. In this case, swimming is mostly a defense mechanism to avoid terrestrial predators, though they have been known to eat crustaceans. This supplements their mostly herbivorous diet of fruits and leaves.

The fact that the males have a larger tail fin, along with their crayon-blue color, suggests another reason for the fin; the same reason Blue Iguanas are blue--it looks sexy. If a male has enough energy to produce a fin that large, and can still escape predators despite being the color of an interstate sign, that means he's got some good genes to pass down to the kids.

The Sailfin Lizard is no longer listed as Vulnerable on the IUCN list. This is not necessarily a good thing. It has been moved to Data Deficient, which means we don't really know how bad it is. Life on a tropical island means habitat loss is almost a given threat, but overshadowing that is the pet trade.

Ah, the pet trade, such a mixed curse. It destroys the wild population, without killing that many of them. If they can be bred in captivity, it means they might be able to be bred to be released. It also means that there can be a higher demand for them, leading to more being taken from the wild. It about killed the Red-Kneed Tarantula and Macaws², but it might save the Axolotl. It looks like it could go either way for the Sailfin Lizard. This guy (where I got the picture) is selling captive-bred Sailfins as pets, and these guys are breeding them the same way to be released into the wild.

¹Dimetrodon are actually more closely related to us than they are to this lizard.
²You do not want a Macaw as a pet. They might be pretty, but imagine having a five-year old child for seventy years. Whose screams can be easily heard for miles. Who can bite through an eighth of an inch of steel.

Put the Lime in the Coconut

Oversized arthropods will always be welcome on this blog. Alright, most arthropods are condidered icky enough, but there is a special type of revulsion saved for really big creepy-crawlies. Well, I've already written about the largest freshwater invertebrate, so the largest terrestrial invertebrate can't be far behind¹. Also hailing from order Decapoda, this is the Coconut Crab (Birgus latro).

Image from Cook Islands Natural Heritage Trust³

When I say "big," I'm sure that you're looking for some measurements to back that up. The Coconut Crab, also known as the Robber Crab or Palm Thief, has a body length of 1½ feet, with a legspan of 3 feet. It weighs up to 9 pounds but its strong claws can apparently lift up to about 60 pounds. Yes, this crab can lift a medium-sized dog.

Why is it so beefy? Well, anyone who has tried to open a coconut with simple tools can answer that. This is not an easy fruit to get into. The Crab will strip the outer husk near the germination pores (those things that make a coconut look like a bowling ball). It will then use one of its legs to punch a hole through the inner husk, and break the coconut apart. Once again, ARKive provides us with wonderful footage of this in action.

Mating occurs quickly and on land, and the female carries the eggs under her abdomen. She then drops those into the ocean, where they hatch into marine larvae that look something like shrimp. Coconut Crabs are closely related to the Terrestrial Hermit Crabs you'd see in pet stores, and the young will find snail shells to protect their soft rear-end. As they grow larger, their abdomen grows a thick carapace, so they lose the need to find snails. Good thing, too, considering their size. They also become fully terrestrial, though they can still drink seawater.

Coconut Crabs are found dispersed throughout islands in the South Pacific. Being a huge crab, no one would be surprised that they're hunted for food. Being an island species also means invasive species like rats, pigs, and ants are a problem for the juveniles. As the islands get more populated, habitat destruction is a problem as people encroach on the beaches. As population estimates vary from island to island depending on the number of people there, the IUCN lists the Coconut Crab as Data Deficient.

Conservation varies from island to island as well. Some places set hunting limits, while others have set up breeding programs. More research needs to be done to really find out how to help these huge creepy-crawlies out.


¹The fact that weight is pretty much meaningless in the ocean leads to some pretty big invertebrates down there. The Japanese Spider Crab²(Macrocheira kaempferi) with a 13 foot legspan wins as the largest arthropod, while the Colossal Squid (Mesonychoteuthis hamiltoni) puts all other invertebrates to shame with a body length of 33 feet.
²You can't tell me that picture doesn't look like a video game boss.
³The image that many of you were expecting to see was probably this one, which I would have used if I could have found an original source.

When I Get Home

I know, I know. The monthly idea didn't work out so well and I ended up missing August (and almost September). Expect a post in October, or, better yet, suggest an EUT for me to write about. Phantom Midge suggested the Oregon Forestsnail (Allogona townsendiana), but the blog that she linked to was well written enough that I don't think I would have much to add. So, a random ARKive search turned up a big beetle that is one heck of a homebody.

This is the Frigate (or Frégate, depending on your language) Island Tenebrionid Beetle (Polposipus herculeanus), and it is the largest known tenebrionid in the world. For all of you non-coleopterists out there, tenebironids are better known as Darkling Beetles¹, and their larvae are far better known as mealworms. In day to day life, mealworms are seen in two situations: you either have a pet insectivore², or you have flour that has been in your pantry far too long.

Now that we know a little about the family, on to the Frigate Island Beetle itself. Sources give it's length as 20 to 30 mm. That might not seem like much, but look at that picture again. That's not a small beetle. They are completely flightless--probably due to their size--and don't get around much. They spend the entirety of their lives on a few dead trees in a small area. The absolute farthest that they've recorded this beetle traveling is a whopping 19 meters³. The beetle is apparently able to find all its life needs on the few dead trees within those 19 meters. I haven't found what it eats, exactly; I wouldn't be surprised if scientists weren't sure. Looking at its kin, I would guess that the rotting trees are their main food source.

The Frigate Island Beetle has a fun defensive mechanism that I wish I had a visual for. It will, when threatened, exude a purple, stinking, staining chemical. I'm sure the t-shirts of the visiting entomologists look lovely after a day of research.

Frigate Island itself is a tiny island within a larger archipelago called Seychelles, just north of Madagascar. Of course, being from a small, pretty tropical island means that two things are threatening the beetle population: habitat loss and invasive species. A recent program to eradicate the rats (it's always rats) was succesful. Cooler still, the London Zoo has a breeding program, and you can even (figuratively) adopt a Frigate Island Beetle.

By the way, the Coconut Crab is also from Seychelles, and is listed as Data Deficient. It will likely get a post in the near future.



¹Not Darkwing, Darkling!
²I, for example, have a tub of 50 in my refrigerator for my Leopard Gecko.
³Even for a beetle, this is small. The American Burying Beetle is not considered a distant traveling beetle, and is about the same size as this one, but can travel two miles on the scent of carrion.

I Want my Baby Back

I apologize for the unintentional hiatus last month, but I start as a Master’s student next month, and preparations for such have gotten in the way of blogging. As it sounds like my workload will increase massively once school actually starts, don’t be surprised if Endangered Ugly Things continues on a monthly schedule for a while. I hate to say it, but in a fight between my blog and my education, my education wins out (barely).

Two weeks ago, both my girlfriend and my aunt sent me a link to MSNBC’s article on the “Top 10 Oddballs of the Animal World,” highlighting what they consider the weirdest looking animals out there. I hate to say, I could probably give some of those a run for their money¹. It did point me back to EDGE’s amphibian list with a burrowing frog similar to the one I wrote about in May. I was worried about featuring another amphibian so soon (Ha!), but the Conservation Issue of The Year is the amphibian decline, so maybe two frog posts are justified. That, and this one deserves it.

The Myer’s Surinam Toad (Pipa myersi) belongs to a genus of frogs whose looks never fail to gather attention. As (according to EDGE) one naturalist put it:

"…looking – as all pipa toads look in repose – as though she had been dead for some weeks and was already partially decomposed."

A lovely image, though probably quite helpful in camouflaging themselves among the leaves within the Panamanian swamps they call home.

As swamps are not exactly known for their clarity, Surinam Toads have reduced eyes. They instead rely on fancy lobed fingers to feel out their prey, which they then grab or simply vacuum up—long sticky tongues simply won’t work underwater. Their prey preference appears to be what I like to call “any animal smaller than its head.”

What I find truly ugly about Surinam Toads is not the fact that they look like an unfortunate road-kill accident. It’s their baby rearing techniques. During mating, the couple maneuvers themselves such that about 100 eggs are spread along the sticky back of the female. These are gradually absorbed into the skin, where the young develop. Most Surinam Toad young go through their entire metamorphosis in their mother’s backs, emerging as tiny froglets (seen here²). The Myer’s Toad lets the kids out a little early, with the young emerging into the world as tadpoles.

If you’ll find the range map on the EDGE website, you’ll get an idea why Myer’s Surinam Toad is listed. If anything has a total range of less than 5000 sq. km, then it automatically gets on the endangered list. Habitat loss and fragmentation is probably aiding in their decline, though too few have been found to conduct a thorough population estimate. They are found in a reserve, so there may be hope to see baby tadpoles pushing their way out of their mother’s skin for years to come.


¹Both my girlfriend and Phantom Midge have suggested I write about the Yeti Crab. However, so little is known about it that it isn’t listed anywhere, as well as the fact that there is only one photograph of it. I do think it should be adapted into plush form, though.
²It should be said that I find this creepy enough that I can’t watch the entire video. It looks like something from a horror film.

Dr. Worm

A friend of mine found an exciting Endangered Ugly Thing that I knew I had to write about. Nothing fits so far outside the "charismatic megafauna" category as a giant earthworm.

While the Giant Palouse Earthworm (Driloleirus americanus) is not the largest earthworm¹, a three foot long earthworm is nothing to sneeze at. Especially when it smells like flowers. Yes, while other animals thrash or bite or musk when handled, the Giant Earthworm emits a flowery scent. Smelling like lilies, in fact. No one knows why. It is also said to spit and run (slither?) away to avoid predators. One local conservationist has been oft quoted as saying, "This worm is the stuff that legends and fairy tales are made of." I want to know what fairy tales he's been reading.

The Palouse region from which the Earthworm derives its name is an area of eastern Washington and northern Idaho that was dominated by thick prairies. However, as of today, most of the area has been converted to agricultural use. While the Giant Earthworm never tends to directly contact surface vegetation--what with living in burrows 15 feet underground--it can still be affected by the change. This habitat loss, as well as competition with invasive worms² has led to the Palouse Giant Earthworm's decline.

Like a few other animals I've written about, the Giant Palouse Earthworm went a long time without any sightings. Unlike, for example, the Long-beaked Echidna, they've recently found another specimen. In 2005, a grad student from the University of Idaho found one, and it is now preserved in formaldehyde for posterity. While the IUCN has listed it as vulnerable, the US Fish and Wildlife Service seems reluctant to federally list it. This, of course, has put conservationists in an uproar. But hey, if this kind of controversy can produce stories in multiple newspapers, teaching more people about new vulnerable animals, it can't be all bad.

¹ That honor belongs to the Giant Gippsland Earthworm (Megascolides australis) from Australia, which can grow up to 9 feet.
²Most earthworms you come in contact with in North America are invasive. Now you know.

Purple Haze

As a comment on my Copperbelly Watersnake post, Gargoyle Grins asked—very nicely—for a post on the Purple Burrowing Frog. I’m not sure when the comment was made, but I only saw it recently. I am more than happy to oblige a reader.

Having only been formally described in 2003, there is a surprising amount of information known about the Purple Burrowing Frog (Nasikabatrachus sahyadrensis). So far, it has only been found in two small areas in Western India, where it spends most of its time buried underground.

There are two major reasons for its subterranean lifestyle: it’s moist underground, and that’s where the termites live. With minimal eyes¹, the Purple Burrowing Frog relies on smell and touch to hunt. The pointy nose is useful for shoving through termite’s walls, and it has a tongue specially shaped for sucking up the little morsels. The Purple Burrowing Frog depends on termites for more than just a food source. The structures and tunnels built by the termites help aerate and moisten the soil. It is the only burrowing frog that feeds underground; all others simply hide in the dirt to avoid predators.

During the monsoon season, however, the frogs come out to breed. They make their way to nearby water sources, and begin the mating process. Due to similarities to other species, it’s probable that the male temporarily glues himself to the back of the female during amplexus. Since it was only discovered in 2003, there are still quite a few uncertainties about its lifecycle.

Our lavender friends are listed as endangered by the IUCN because the range it has been found in is so small, and the forests under which they dig are threatened by expanding cultivation. Much more needs to be learnt about this animal before conservation efforts can be put into place.

¹Eye reduction happens a lot in underground animals.

Black Bead Game

I really wanted to write about the whipscorpion that Phantom Midge found, but I hate to say, there is little to no information about Trithyreus shoshonensis. So, my fall back this week is an animal that I got a picture of during my spring break trip to the Columbus Zoo. Growing up, I remember learning that the Gila Monster was one of two venomous lizards. This is the other one.

Image by me

Yes, the Mexican Beaded Lizard (Heloderma horridum) looks a whole lot like the Gila Monster. This so happens because they are within the same genus, and the major differences are that the Gila Monster is smaller and more colorful. Not having the hinged fangs of vipers, the Beaded Lizard delivers venom that flows along grooves in the teeth, and delivers by chewing. Digimorph gives a wonderful visual of that—check out the horizontal dynamic cutaway¹ and watch for the hollow bottom teeth. The venom is used mainly as a defense mechanism, and is typically non-fatal to humans—if you get medical treatment quickly enough. The small animals they prey on…well, that’s a different story.

The “beads” from which this lizard gets its name are osteoderms²: tiny bits of bone growing within the skin that lead to its studded appearance. This adds another layer of protection on top of the fact that they can maim with a single bite. They inhabit the scrublands and other semi-arid habitats of Western and Southern Mexico, explaining the other part of their name. Like some other arid-adapted lizards, the Mexican Beaded Lizard can store fat in its tail to provide food and water during times of scarcity.

Habitat loss, due to clearing for agriculture, is one large factor in this species’ decline. The one that really surprises me, however, is the pet trade. I’ve always been an avid fan of reptiles, and have no problems with keeping some as pets. But I draw the line at an animal that can kill me if improperly handled. To help stop this problem, they are listed by CITES, and there are breeding and head start programs to replenish their numbers in the wild.

¹Yes, it’s actually a Gila Monster. The principle is the same.
²Meaning “bone skin.”
