More Info: India is home to 3 crocodillian species : the mugger or marsh crocodile (Crocodylus palustris) the estuarine or saltwater crocodile (Crocodylus porosus) and the gharial (Gavialis gangeticus)
The gharial crocodile has a characteristic elongated, narrow snout and adult males develop a bulbous growth at the tip of their snout, called a "ghara" after the Indian pot it resembles. The ghara helps with vocalisation and also gives a visual signal to attract females. The gharial is the longest of all living crocodilians and is found in the major river systems of India, including, the Ganges, Chambal, Mahanadi and the Son.
The Mugger crocodile or marsh crocodile is a hole-nesting species, which lays eggs during the annual dry season. It has the widest snout among all crocodile species. It can live in fresh water and coastal saltwater lagoons as well as man-made reservoirs. This species is generally considered to be occasionally dangerous to humans, but nowhere near as notorious as the much larger (and, in India, less common) saltwater crocodile.
The saltwater crocodile is found in the eastern states of Odisha, West Bengal, Andhra Pradesh and Tamil Nadu. Saltwater Crocodiles are the largest species of crocodilians family and largest of all living reptiles in the world. They are found in saline and brackish mangrove swamps of Bhitarkanika and Sunderbans.
