terrancem (1928624) writes "A creature discovered by engineers building a dam in the Amazon is a type of caecilian, a limbless amphibian that resembles an earthworm or as some are noting, part of the male anatomy. The animal was discovered while draining a portion of the Madeira River — a major tributary of the Amazon — for a controversial hydroelectric project. Six individuals were found according to biologist Julian Tupan, who identified the species as Atretochoana eiselti. Little else is known about the species."
