The critically endangered gharial (Gavialis gangeticus) adult males have a giant wart at the end of the snout, which resembles an earthenware pot known as a ghara, hence the name "gharial". Also known as the fish-eating crocodile, it is a crocodilian in the family Gavialidae and among the longest of all living crocodilians - up to 20ft. The gharial is well adapted to catching fish because of its long, narrow snout and 110 sharp, interlocking teeth. The oldest known depictions of the gharial are about 4,000 years old. It is the most thoroughly aquatic crocodilian, and leaves the water only for basking and building nests on moist sandbanks.
