Atretochoana eiselti, is nicknamed as the *male organ* snake for the reason you know very well. Anyway, it’s neither that male body part nor a snake. In fact, it’s a limbless amphibian. For over a century, people only knew of this p***s snake which is, by the way, the largest tetrapod without lungs and was only believed to exist because of Sir Graham Hales who conserved two specimens in the late 19th century until it was rediscovered in 2011.
