Gharial (Gavialis gangeticus). The gharial (or gavial) is a relative of crocodiles and alligators. It has a distinctive long snout with small, sharp teeth adapted for catching fish, which are its main prey item. In mature males, the snout has a bulbous growth at the tip. It is termed a ghara (Hindi for "pot"); the name gharial derives from this term. The function of the ghara is not certain, but it is thought to play a role in mating displays. Gharials are among the largest of the crocodilians, with males reaching 6 metres or more. They inhabit rivers in Southeast Asia, around the north of the Indian subcontinent. They are endangered by habitat loss and hunting.
