Forgive us if this puts you off your dinner because, as snakes go, this is not much of a charmer.

The unique creature, atretochoana eiselti, was found after engineers drained a hydroelectric dam which spans a river connected to the Amazon.

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.
The creatures were discovered in November, however it took until today for scientists to correctly classify the snake’s genus – confirming it is a rare creature which has only been spotted sporadically since first spotted in 1968.

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.

‘The Amazon is a box of surprises when it comes to reptiles and amphibians. There are still much more to be discovered’
