Waltzing Matilda

Recently, a new species of snake was discovered in the Tanzanian rainforest. It belongs to a genus of viper whose hemotoxic¹ venom has no known antidote. It is named after a young woman who has the honor of being one of the first people to take care of it. She happens to be seven.

This is Matilda's Horned Viper (Atheris matildae). The Matilda in question is Matilda Davenport, daughter of Tim Davenport, director of the Wildlife Conservation Society's Tanzania program. She took an early interest in the specimens the research team brought in. They began to unofficially refer to the snake as "Matilda's Viper," and, before long, it was no longer unofficial. Though it seems that Matilda's younger sister now wants a species named after her too.

The location of Matilda's Horned Viper are being kept under wraps, as the researchers fear poachers may come after this exotic and brightly colored snake for the pet trade. They've started a breeding program to provide individuals to zoos to allow the public to get their first glimpse of this gorgeous snake.

No One Like You

For October, Jonathan Wojcik of Bogleech agreed to do a guest post for Endangered Ugly Things. Check out his site for all the information you could ever want about monsters, real or imagined. Enjoy!

There are over a hundred thousand named Arachnids crawling around on our planet's surface, and America is more aware of them this time of year than any other season. Famous though they are, these ubiquitous terrestrial predators are seldom evaluated for their conservation status, and the exceptions have consisted almost entirely of spiders - really only one of several strange and incredibly ancient Arachnid groups.

Image by Gilles San Martin

Currently, there are at least two non-spider Arachnida recognized as threatened, and both of them belong to the family Lycosidae, or "pseudoscorpions." Though found virtually everywhere, these mostly blind predators go largely unnoticed due to their subterranean habits and incredibly small size - so small you can find them preying upon mites, lice and springtails between grains of soil, under the wing cases of beetles, in the fur of mice or between the pages of dusty, moldy old books. Many species will even use far larger, flying insects as transportation, grabbing into their leg hairs with a single claw and letting go at the next landing.

As their names imply, pseudoscorpions are entirely separate from the true scorpions, lacking the venomous tails but bearing very similar pincers which, in many species, can inject venom through the lower thumb-like claw. As an added bonus, they can also regurgitate a corrosive enzyme over stunned prey and secrete silk from their jaws, usually used to build igloo-shaped cocoons in which they molt and overwinter. Mating typically involves a "dancing" ritual where the male, locking pincers with the female, guides her over a sperm packet he lays on the ground. Like many other arachnids, females will carry their babies on their backs until tough enough to fend for themselves.

These minute animals have existed in more or less the same form for over 380 million years, but at least two species could disappear on us at any moment.  Known endangered Lycosids include Fissilicreagris imperialis and Tartarocreagris texana, the Empire cave and Tooth Cave pseudoscorpions. Like many other creatures you can read about on EUT, these troglobytes are completely unique to their respective cave systems and have adapted to survive in no other environment. Any unusual activity can be disastrous for cave dwelling organisms; even a few careless spelunkers or a trickle of urban runoff can disrupt conditions that have remained unchanged for eons.

A staggering portion of the human race suffers from unreasonable levels of terror associated with eight-legged arthropods, but it's not fair to let a widespread phobia cloud our concern for the plight of any species, large or small. If more of us could get past our fears and appreciate just how weird, cool and useful the Arachnids are, we might be seeing quite a few more of them not only listed, but actively protected. Right now, eyeless micromonsters are dancing in each other's arms in pitch darkness, and surely deserve as much as any other animal to continue doing so for ages to come.

Dirty Little Sea Kraits

(Alternative title: Krait Expectations)

It seems that media attention of non-charismatic species is growing. I recently had an interview with a French news site, which can be found here. Also, my wife (I’m still getting used to saying that) has taught me how to needle felt. Remember how I complained that there’s no such thing as a plush Lamprey? There is now. I would like to make more plush EUTs, but I need suggestions about which ones to create. Please leave suggestions, and I promise you’ll see them by the next post.
















The Rennell Island Sea Krait (Laticauda crockeri) is like most other Sea Kraits in many ways: it uses its wide paddle tail and venomous bite to hunt fish. On the other hand, it is smaller, not striped, and, oh yeah, doesn’t live in the sea. Instead, they’re found in the brackish Lake Tegano in the Solomon Islands.

I suppose I should back up somewhat. Sea Snakes are exactly what they sound like—snakes that are well-adapted to marine life. They have large, oar-like tails for propulsion, smooth scales for less drag, big long lungs for hours of underwater hunting, and potent venom for easy hunting. Because of these traits, most of them hardly ever make it on to dry ground. Sea Kraits, however, are the least aquatically adapted of the Sea Snakes, with rougher scales and smaller tail fins that allow them to manage better on land.

Due to the small size of the range of the Rennell Island Sea Krait—that is, half of a small island in the South Pacific—it is automatically considered Vulnerable by the IUCN. However, the minimalistic human use of the island has helped keep the area pristine. While there is tourism, it seems to stay within the realm of nature observation with little impact on the ecosystem.

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.

Alabama on My Mind

(Alternate title: Plays by Sense of Smell)

I got an urge this month to write about a blind cave animal, knowing that there are some exciting organisms that I've missed so far. I even went so far as to search "endangered blind cave," knowing that something interesting could fit after that description. Well, a number of animals can, such as the endangered Texas Blind Salamander, which lives within the same cave system as the Arachnids I've written about previously. However, on the second page, I saw a mention of the Alabama Cavefish (Speoplatyrhinus poulsoni) and decided to see find what I could find.

Image from Aldemaro Romero

The "proper" term for a completely cave-dwelling animal is "troglobite," and this term comes with a set of characteristics that the Alabama Cavefish does a wonderful job of illustrating. Troglobites¹ are small (not a lot of nutrients make their way into the caves), eyeless (when it's this dark, eyes aren't sensory organs, they're disease ports), and a range of colors from white to transparent (color just wastes precious nutrients when a] it's pitch black and b] no one around has eyes anyway). Other sensory organs go into overdrive to make up for the lack of eyes. Take, for example, the lateral line. In most fish, it is a row of cells that allow fish to sense vibrations in the water--effectively acting as fish ears. Well, in the Alabama Cavefish, that line becomes a network covering the entirety of the fish, shown beautifully in these pictures. If we stick with the "fish ear" analogy, I suppose it's not that different than most bats developing big honkin' ears. They also have large sensory papillae (read: fish noses) that help them sniff out prey in the dark.

The discovery of the Alabama Cavefish sounds like quite an interesting story. In 1966, John Cooper was a Ph.D. student studying the ecology and taxonomy of cave crayfish, and was thus well versed in the common troglobitic fish found in the area. Seeing what he thought was a Southern Cavefish, he caught it, looked at it, and yelled to his wife (who was apparently fine with following her husband down dark, cold, wet cracks in the earth), "This ain't Typhlichthys, it's something nobody ever seen before."² After a few more sampling trips to Key Cave, and years in front of a dissecting scope, the species was officially named.

Three years later, it was listed as threatened. Despite frequent (and difficult) excursions into Key Cave, no more than ten Alabama Cavefish have been seen at the same time, causing guesses about the population size to be nothing more than guesses. One of the biggest worries that researchers have is that something will happen to the Gray Bats (also endangered) that roost in the cave and bring nutrients into the cave in the form of poop. The bats eat outside insects (mosquitoes and the like), poop in the cave, which is eaten by bacteria, which is eaten by amphipods and isopods, which are eaten by the Cavefish. If the bats get messed with, then the whole system falls apart.

To protect these now critically endangered fish and their habitat, the entire site is now a National Wildlife Refuge. The cave is not open to the public, which protects the bats and fish, and the refuge itself provides a buffer between the caves and nearby development, which would mess with the groundwater flowing into these isolated sanctuaries.


¹ Alabama Cavefish are more properly called "stygiobites," which are aquatic cave-dwellers. While "troglo-" refers to caves, "stygio-" refers to the River Styx. If you're wondering, the "-bite" is just "bio-" as a suffix.
²Don't even bother trying that five times fast. Try saying it twice, at any speed.

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.

I'm Not Dead

Last month, Phantom Midge made a wonderful suggestion for an EUT that I hadn’t thought about. I had known about it for ages, and, like her, had been pronouncing it wrong for years¹. Somehow, without any foreknowledge, I’m managing to post this on an exceedingly appropriate day, as today is the 70th anniversary of its discovery as a living animal.

^{Image from Dinofish}

Order Coelacanth (pronounced See-la-canth) had been well documented since 1836, and fossils show that it lived for 345 million years between the Devonian period and the end of the Cretaceous period, when the dinosaurs died out. This must have come as a big surprise for the West Indian Ocean Coelacanth (Latimeria chalumnae) caught by fishermen off the coast of South Africa in 1938. These fishermen were friends with the curator of a small, local museum, and she would frequently check through their catch for anything interesting. Needless to say, something interesting was, in fact, found. Dinofish, who seem to be experts on this matter, have the whole long story on their site in far more detail than I can manage.

Coelacanths spend most of their time in deep (90-200m) caves, where they suction feed on any fish smaller than their head. Exceedingly sensitive eyes, along with an electro-sensory organ help them hunt. These are not small fish, getting up to about 6 feet in length and weighing about 175 pounds, thus surpassing the other “Living Fossil” fish I wrote about². Coelacanth tail fins are split into three fleshy sections, and all eight of their fins move in a mesmerizing, visualized wonderfully—as always—in an ARKive video.

I was surprised the Coelacanth is listed at all, much less as Critically Endangered. I thought there would be far too little information on its numbers and habits to be called anything other than Data Deficient. Analyses of populations in 1989 suggested that there might only be 500 individuals left. The low population, ironically enough, might be attributed to by-catch. This could explain why all the natives were so perplexed when the Europeans got excited by the catch of a fish they knew to be inedible³. Since then, conservation and outreach programs have given fishermen the tools to release the fish directly back to the murky depths from which they came.


¹In Freshman Zoology, I made a list of letter combinations that made an “s” sound. “Coe” always annoyed me, because I’ve never seen it outside of biology.
²Wikipedia has some nice articles about the term “Living Fossil.” Coelacanths are a “Lazarus taxon,” while the Australian Lungfish falls into the wider “Living Fossil” expression. I don’t think I’ll ever get a chance to write about an “Elvis taxon.”
³Never underestimate the local population when it comes to ecology.

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.

Image from EDGE

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.

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.

Image by S.D. Biju via EDGE

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.

Up to My Neck in Trouble

I have found that I can no longer visit zoos without specifically looking for EUTs. I suppose this isn’t a bad thing, as it’s always useful to expand my repertoire. On the other hand, it makes the experience slightly insufferable for people who come with me. Sorry. This time, it was again my home zoo, the Columbus Zoo and Aquarium. There were a few good turtles, but I had to choose one over the other. One had to fall by the wayside, because a) it is slightly cute (as evidenced by my girlfriend going “aww” upon seeing it), and b) the picture didn’t turn out nearly as well¹.

Image by me

The Roti Island Snake-Necked Turtle (Chelodina mccordi) is fairly aptly named. It is found on Roti Island, which is a 460 square mile Indonesian island, and it does, in fact, have a snake-like neck. There is even a video of this turtle on YouTube, taken at the Columbus Zoo. Like a number of EUTs before it, it’s creepier when it’s moving.

For some reason, I am having problems finding specific answers to why it has such an elongate neck. It is an opportunistic carnivore, and having a neck it can whip around is probably helpful in catching the quicker things, like small fish and tadpoles. Much like the Map Turtles and Red-Eared Sliders I’m used to, the Snake-Necked Turtle is semi-aquatic, so it typically spends most of its time in lakes, swamps, and rice paddies.

There are two major threats to the Snake-Neck’s survival. The first one is simply the fact that it has a small natural range, so there were fewer of them to begin with. The big issue, however, is the pet trade. Its sister species, the Eastern Snake-Necked Turtle (Chelodina longicollis) is one of the most frequently-kept turtle species in Australia, and the Roti Island Snake-Neck is paying for it. As demand increases, the most economic thing to do is to increase supply, and up the price. Roti Island Snake-Necked Turtles can fetch anywhere from $300 to $500 on the black market.

This is exactly the sort of thing that CITES was created for. Now, any international trade of this turtle requires the right permits. It’s also been upgraded (downgraded?) to Critically Endangered on the IUCN red list. Other conservation programs have taken an interest, and there are breeding programs set up, though some confusions with similar species² has slowed down the process some.

¹For those who are curious, it was the Fly River Turtle (Carettochelys insculpta), which is neat because it’s a freshwater turtle that looks like a sea turtle.
²As infallible as we’d like to think we are, biologists don’t always get it right.

Blacksnake

Image from FWS

In April, I mentioned an Ohio endangered species that got some cable airtime, and rightfully so. Mike Rowe from Dirty Jobs¹ traveled to Ohio’s north coast (that is, Lake Erie) to spend some quality time with someone I am proud to say that I (very briefly) worked with.

The Lake Erie Water Snake (Nerodia sipedon insularum) is, like most water snakes, very angry. They’re not venomous or dangerous in any way, just large and inclined to bite and musk. How large, you ask? They can get up to 3.5 feet. This “musking” is a defensive mechanism in which they spray the smelly contents of their cloaca³ all over whomever has grabbed them. It’s not pleasant.

They make their home on Kelley’s Island, a small (8 square miles) island just 3 miles off the coast of “Mainland” Ohio. I suppose that’s inaccurate, as that may be their geographic location, but they really make their homes squeezed among boulders of the rocky coast. From there, it is a short slither into the lake for some fishing. Water Snakes live up to their name well, as they are agile hunters in the water, and eat their share of small fish, frogs, and other similarly sized aquatic wildlife. They may be the same species as the common Northern Water Snake (Nerodia sipedon sipedon), but as a separate population, they are entitled to their own protection.

As Kelly’s Island is a popular resort town, the snakes were not exactly the most welcomed of natives. For years, they were tormented by locals and visitors until, in 1999, there were less than 2,000 left. In May 2000, they were added to the Ohio and Federal Endangered Species Lists, and signs declaring “Save Our Snakes” were distributed through the island. Kristen Stanford, in an effort to change public thought surrounding these snakes, has become the Island Snake Lady, and the Lake Erie Water Snake population is now up to a minimum estimate of 6,500 individuals—not bad for seven years. The way she reaches the public is by reaching the children. At one herpetological meeting, she talked about a grandmother who wouldn’t harm the snakes any more because little Jimmy (name changed to protect the innocent) had talked with the Snake Lady, and the Snake Lady said the snakes were good.

Anybody who lives around the Great Lakes knows that the invasive Zebra Mussels have become an ecological nightmare. Well, not long after they were introduced, a natural predator of theirs, the Round Goby, was also (accidentally) brought into the lakes. This didn’t particularly lower Zebra Mussel populations, and Round Gobies boomed. However, the Lake Erie Water Snake seems to feed increasingly on these alien invaders. If the Gobies eat the Mussels, and the Water Snakes eat the Gobies, we might be one step closer to solving that problem.

¹One of my dreams is to have a research job so disgusting that it can be featured on a show like that².
²Another is to host a show like that.
³Latin for “sewer”. You can probably guess what it is.

She's a Rock.....House!

This is going to be another post where I’m going to try to whip up enough paragraphs with minimal information. I know enough about their order, but little about the species themselves. As adults, they look like small, oddly shaped moths.

Image from University of Michigan

On the other hand, as larvae, they are strangely shaped, grub-like, and quite ugly. On the Ohio Endangered Species list, there are three Caddisflies (Order Trichoptera, the species are Chimarra socia, Oecetis eddlestoni, and Brachycentrus numerosus). “Trichoptera” means “Hairy Wing,” not to be confused with their sister order, the Lepidoptera (“scaly wing”).

As larvae, Caddisflies inhabit streams and rivers all over the world, though I wouldn’t be surprised if the listed species had a much-reduced habitat range. Most of the life cycle is spent as a larva, usually at least a year. Many species attach bits of detritus to their bodies, such as in the picture, to act as a protective shell. The shape and material of the shell can even be used to classify the animals. To grow into big, strong adults, young Caddisflies will eat most anything they can catch. In fact, some even secrete a silky thread, like their caterpillar cousins. However, the Caddisflies use it to form a net and catch yummy detritus flowing by their home.

Most of that was off the top of my head, after spending the summer studying the small streams (technically known as Primary Headwaters) in the Cuyahoga Valley National Park. I know much less about them as adults. In fact, before doing some late night collecting for my Invertebrate Zoology course this fall, I couldn’t have told you what the adults even looked like. Of course, now I know they look like small, unexciting moths that hold their wings so they form a peak over their body¹. Their mouthparts aren’t as exciting as butterflies’ or moths’, and about all they can do is suck up liquids. This doesn’t matter terribly much, because they have at most a month to have sex, lay eggs, and die.

Now, why are these three endangered, as opposed to the approximately 250 other species of Caddisflies found in Ohio? I’m not terribly sure. I’ve got guesses though. These might only be found in a few counties in Ohio². They may also be endangered because the small stream habitats in which they are found are at risk from development, pollution, or the like.

That’s where Ohio is ahead of the game… to an extent. Because the Cuyahoga River burned in 1969, just in the midst of an environmental awakening³, state and federal Environmental Protection Agencies came into existence. Ohio developed some pretty good river assessment protocols. However, in 1999, they realized that small streams leading into the larger streams need to get cleaned as well. Therefore, they set up Primary Headwater Habitat conservation efforts that look at the quality of small streams, which are similar to the ones that our squirmy friends spend their childhood.

Oh, by the way, I noticed that I haven’t gotten a single comment in five weeks. If you feel like you have anything to say at all, good, bad or indifferent, please comment. Especially if I’ve gotten something wrong. I’d really like this blog to be as accurate as possible.

¹I’m sure I’ve seen tons of them before that, I just couldn’t have told you it was a caddisfly.
²Phantom Midge, I don’t know how you found that out for Rheopelopia acra, but that was impressive.
³That wasn’t the first time it caught fire. It was just the one that got noticed.

Calling On - Weta

I was going to write about the Hairy Marron, the fuzzy crayfish from Australia, but I couldn’t find enough information about it, least of all why it’s hairy. So, this week’s post is about the other arthropod I mentioned in the footnote of the Hunter Slug post.

Image by Gerald Cubitt via ARKive

Wetas are cricket-like insects native to New Zealand and frequent (possibly even preferred) prey of Tuataras. The Poor Knights Weta (Deinacrida fallai) belonging to the genus of Giant Wetas¹, is amongst the largest insects in the world. They approach 8 inches in size when mature. As they are flightless, being light is not a concern, and thus, when laden with eggs, they can be heavier than sparrows.

The Poor Knights Islands are two small, uninhabited islands off the coast of New Zealand, apparently named for their resemblance to French Toast. Personally, I don’t see it. The islands are a nature reserve, and the 800 meters around the islands are protected as a marine reserve, and apparently a great diving spot². The trees on these islands are where these Weta live, moving to the ground to lay eggs. They may also live on another nearby island, as a Giant Weta fecal pellet was found there. Please, don’t ask me how they determined that it was from Giant Weta.

Poor Knights Wetas are nocturnal and herbivorous, and their main defenses lie in being gigantic and spiky. An adult female can lay 200 to 300 eggs per clutch, which appears to be a one-time deal in a two-year lifespan. They’re listed as Vulnerable by the IUCN, even though they don’t seem to be declining. What they’re really worried about is the small size of their distribution, contained to small islands. They're also worried about the risk of a simple introduction of a non-native predator and its effects. The Wellington Zoo in New Zealand has a breeding program, both as a safeguard against extinction, and for public education.

¹The genus name, according to Wikipedia, means “Terrible Grasshopper”.
²At least, according to the Tourism Department

Oh, Caecilian, You're Breaking my Heart

Within amphibians, there are the frogs and toads (order Anura; it means tailless), which can be considered too cute to include on this blog and there are the salamanders and newts (order Caudata or Urodela, both meaning with a tail), which I’ve already posted about one¹. There is a third order of amphibians, of which most people have not heardof. The scientific name for the order is either Gymnophiona (naked snake) or Apoda (footless), both of which are stunning endorsements for the inclusion of a caecilian on this blog.

Image by John Measey

The Sagala Caecilian (Boulengerula niedeni) is a species that was first described in 2005. Its name comes from the hill it inhabits (Sagala Hill in southern Kenya). Since they’re such a newly discovered species, there’s a lot that still isn’t known about them, but scientists are pretty sure that their range is about 30 sq. km, which is smaller than Manhattan Island. Right there, with that small of a range, they become listed as Critically Endangered. Along with its already minimal range, large-scale farming disrupts streamside habitats, where they make their home, and introduces pollutants.

I’m having problems finding specifics about the Sagala caecilian, such as what it eats (probably small invertebrates) and specific reproductive history, though caecilians are the only order of amphibians that perform internal fertilization. In fact, the discerning feature of this amphibian, used to describe it as a new species, is its oddly shaped phallus.

On a different note, I have received my Official EUTshirt, and I am pleased with the quality. The concept of a cute lamprey stuck with me since I wrote about it. I asked friends and family if the idea of a line of cute Endangered Ugly Things t-shirts went against everything EUT stood for, and they said, “Maybe.” Well, they’re up and buyable anyway. Enjoy, and I’m up for any suggestions of other EUTs, since I’m having slight problems finding good ones.

¹Possibly more to come, ‘cause if you thought the hellbender was big and ugly, there are some bigger, uglier ones out there.
