Engineers working on hydroelectric dam in Rondonia on the Madeira river connected to the Amazon, found this unique creature christened 'atretochoana eiselti', the 'Daily Mail' reported.
The creature neither has eyes nor colorful scales like other snakes, and scientists believe it is closely related to salamanders and frogs family.
"Of the six we collected, one died, three were released back into the wild and another two were kept for studies," Biologist Julian Tupan was quoted as saying by the paper
Found near the mouth of Amazon river, this snake-like reptile survives in warm and fast-flowing water, and scientists confirmed that this rare creature has only been spotted sporadically since it was first spotted in 1968.
"Despite looking like snakes, they aren't reptiles and are more closely related to salamanders and frogs," he confirmed.
It was first discovered in South America in 1968, but was only discovered on the island of Mosquiro last year.
"We think the animal breathes through its skin, and probably feeds on small fish and worms, but there is still nothing proven," Tupan said.
