The creature - about 168mm in length and pink in colour - belongs to an enigmatic, limbless group of amphibians known as the caecilians.

Ramachandran Kotharambath, lead author of the report, told the BBC Tamil Service that the animal was identified as a new species following extensive comparisons with other, similar examples from this amphibian group.

According to the researchers, specimens of the novel caecilian - named Gegeneophis primus - were collected during field works in two consecutive monsoons, first in October 2010 and then in August 2011.

They were discovered at a valley on a plantation in the Wynad district of Kerala.

The new finding was made as part of a longstanding research collaboration between the department of zoology at the University of Kerala and London's Natural History Museum. The Central University at Kasargod in Kerala also contributed to of the discovery.
