Atretochoana — Specie of limbless amphibians known as the "penis snake" that was once thought to be extinct until its rediscovery in 2011

The article reads like part of the beginning of a Cthulhu story, especially:

Its skull shows evidence of muscles not found in any other organism.

Examination of the specimen showed it to have a number of unusual features, including the large number of splenial teeth observed by Taylor, but most unusually, closed choanae, which showed it could not fill any lungs it might have.

the question of how it breathes has not yet been resolved.

If your penis looks like that go to a doctor yesterday.

Although it is not a snake, it has been called various common names in the media such as "penis snake", "man-aconda", and "floppy snake", owing to its visual similarity to the human penis.[9][10]

first off, thank you, Wikipedia, for including "man-aconda" in its cited terms. really going the extra mile.

but also, it's wild that thing isn't even a snake. just another limbless amphibian with unknown breathing mechanisms, hiding in the rainforest. way cooler than I thought.
