Description:Bob21 recently uploaded this same picture, calling it a new snake with no further information. The following is the information that was available with the photo: A group of engineers building a dam in the Amazon recently discovered an Atretochoana eiseltiis, better known as a caecilian, which some people might know as a limbless amphibian. But let's be honest, the creature pictured above is a penis snake. The strange creature was discovered while the Madeira River was being drained as part of a damn building project in Brazil's Madeira River. Biologist Julian Tupan said that six penis snakes were found at the bottom of the river.
