Atretochoana eiselti
Atretochoana eiselti is a species of caecilian known only from two preserved specimens until its 2011 discovery in Brazil.
Biologists discovered six of the unusual-looking creatures - each about a metre long - at the bottom of the river-bed on the Madeira river in Rondonia, in Brazil. It is actually more closely related to salamanders and frogs, but appearance-wise looks more like a snake.
Biologist Julian Tupan, who works for Santo Antonio Energy - the company which constructed the dam - said: ‘Of the six we collected, one died, three were released back into the wild and another two were kept for studies.
‘Despite looking like snakes, they aren’t reptiles and are more closely related to salamanders and frogs.
Mr Tupan added: ‘We think the animal breathes through its skin, and probably feeds on small fish and worms, but there is still nothing proven.
