Gharial
The gharial is a critically endangered crocodilian with a long, narrow snout adapted for catching fish, and is the only living crocodilian with visible sexual dimorphism.
The gharial (Gavialis gangeticus), also known as gavial or fish-eating crocodile, is a crocodilian in the family Gavialidae and among the longest of all living crocodilians. Mature females are long, and males. Adult males have a distinct boss at the end of the snout, which resembles an earthenware pot known as a ghara, hence the name 'gharial'. The gharial is well adapted to catching fish because of its long, narrow snout and 110 sharp, interlocking teeth.

Lore & Background
The oldest known depictions of the gharial are about 4,000 years old and were found in the Indus Valley. Hindus regard it as the vehicle of the river deity Gaṅgā. Local people living near rivers attributed mystical and healing powers to the gharial, and used some of its body parts as ingredients of indigenous medicine.
In Their Own Story
The sun hung low over the Chambal River, casting long, golden shadows across the shifting sands where a massive male gharial lay motionless. To the untrained eye, he appeared merely as another log drifting in the current, his scales blending perfectly with the riverbank's earth tones. Only the faint ripple of water against his narrow snout betrayed life. Suddenly, his head snapped forward with terrifying speed, jaws snapping shut on a shimmering school of fish that had ventured too close to the shallows. He lifted his catch, water cascading from the interlocking teeth, before sinking back into the depths, leaving only a faint wake behind.
Reader's Guide
The gharial is the most thoroughly aquatic crocodilian, and leaves the water only for basking and building nests on moist sandbanks. Adults mate at the end of the cold season. Females congregate in spring to dig nests, in which they lay 20–95 eggs. They guard the nests and the young, which hatch before the onset of the monsoon. The hatchlings stay and forage in shallow water during their first year, but move to sites with deeper water as they grow. The wild gharial population has declined drastically since the 1930s and is limited to only 2% of its historical range today. Conservation programmes initiated in India and Nepal focused on reintroducing captive-bred gharials since the early 1980s. Loss of habitat because of sand mining and conversion to agriculture, depletion of fish resources and detrimental fishing methods continue to threaten the population. It has been listed as critically endangered on the IUCN Red List since 2007.
Did You Know?
