Chinese Giant Salamander


Another day, another endangered amphibian. The Chinese giant salamander is the largest living amphibian in the world, growing up to a whopping 1.8 meters long. They are critically endangered due to over-harvesting for food. They are considered a delicacy in China and also a source for traditional "medicine". Sadly, these awesome creatures are not the only animal facing extinction due to Chinese over-consumption.

Poison Dart Frog


Poison dart frogs are gorgeous, vibrantly colored frogs from Central and South America. They get their name from the fact that many indigenous tribes used their toxins for blow darts. They are also critically endangered, having been decimated by the Chytrid fungus. They are also at risk from collectors, mostly from Germany and Japan, who are attracted to the rare frogs' beautiful colors and patterns.

Unlike some other amphibians, poison dart frogs don't lay a lot of eggs. As a result, they are very devoted parents, carrying their tadpoles piggyback from water source to water source. This lack of fecundity and the dependence on their parents is another reason why collectors are such a threat to the species. Millions of dollars worth of frogs are smuggled out of South America every day.

Collectors aren't the only reason these frogs are so valuable. Their skin contains more than just toxins. They contain chemicals that can be used to treat everything from cancer to Alzheimers to HIV. They are a shmorgishborg of useful and amazing chemicals, and as a result they are in high demand from pharmaceutical companies. Unfortunately, these chemicals and toxins are not innately created by the frogs, they come from the frogs' diet and environment. This makes captive bred frogs useless for research, hence the constant demand for new frogs off the black market. Now I would think that such dependence on biodiversity would encourage pharmaceutical companies to invest money in sanctuaries for these creatures and sustainable rainforests. That way they would have a continual supply of specimens without having to worry about running out or perpetuating an exploitative and illegal black market. But then that's why I don't run a pharmaceutical company.

So lets see, these frogs are adorable, beautiful and varied in color and pattern, caring parents, poster children for the interconnectedness of life, and could possibly save countless lives. Fuck the giant panda, these guys need to be the new face of conservation!

Desman


Today's critter is the desman, a semi-aquatic cousin of the mole. Only two species of desman exist today, the Pyrenean desman and the Russian desman. Both species are vulnerable due to pollution and illegal fishing nets. The desman uses its webbed hind legs and powerful tail to swim through the water as easily as its cousins burrow through the ground. However, the most interesting feature of the desman is its nose. This prehensile trunk features the same Eimer's organ at the tip that the star-nosed mole has. This allows it to reach into nooks and crannies under the water and feel for tasty insects, crustaceans and amphibians. Despite being functionally blind, this organ is so powerful that it can construct as mental picture of its surroundings based on touch alone. Think of him as the combination of Namor and Daredevil, only in tiny mole form.

The desman has a surprisingly complex system of society and communication that is only just now starting to be studied.

Purple Frogs






Today we're moving away from extinct animals and on to an animal is very much alive. For now. Meet the purple frog. 

The purple frog is the only surviving member of its ancient family. These frogs lived alongside the dinosaurs 70 million years ago, but today can only be found on a tiny spot of Western Ghats, India where they spend most of their lives underground. They only emerge during the monsoon season.

As you can see, the purple frog is a tiny, goofy, bloated sack of fat with a tiny head and protruding nose. I fell in love with these silly looking living fossils and so I decided to sketch out a few different ways of drawing them in cartoon form. They just have such a lovable, un-frog-like old man face. I colored my favorites above.

Sadly, the purple frog is one of many amphibians currently at risk of extinction. Their habitat is being destroyed for cultivation. Thankfully, Edge of Existence, to whom I linked above, is currently working on a number of projects both to further research of this remarkable species and to help farmers find ways to co-exist with it.
