Geographical Distribution
The saltwater crocodile is found in the Indo-Pacific region, including India, Bangladesh, Sri Lanka, Indonesia, the Philippines and Australia. It was once present in Vietnam and southern China but has become extinct in these regions due to human activities. In India, it is primarily found in eastern states of Odisha, West Bengal, Andhra Pradesh, Tamil Nadu and the Andaman and Nicobar Islands. These crocodiles inhabit the mangroves of Bhittarkanika and Sunderbans, Mahanadi Delta and the swamplands in Odisha and West Bengal, including river systems.

General Information  
The Saltwater Crocodile breeds between November and March. Female crocodiles typically normally lay 40 to 60 eggs, but they can lay up to 90 eggs. After an incubation period of approximately 90 days, the offspring hatch, although this duration may vary depending on the nest temperature, which also determines the sex of the hatchlings. Upon hearing the chirping sounds of the hatchlings, the female excavates the nest to unearth the eggs. Females attain sexual maturity at around 10 to 12 years of age, while males reach sexual maturity later, at about 16 years. Saltwater crocodiles inhabit large, shallow bodies of both freshwater and saltwater, favouring warm, tropical regions. During the wet reason, they reside in freshwater rivers, streams and swamps, but as the dry season progresses and water source diminish, they migrate downstream to saltwater habitats. These crocodiles primarily feeds on fishes but also consume anything they overpower, including turtles, goannas, snakes, birds, livestock such as cattle, buffalo, wild boar and mud crabs. Hatchlings and juveniles, on the other hand, primarily feed on insects, crustaceans, small reptiles, frogs and small fish.   

Threats
- Habitat disturbance and destruction.
- Drowning in fishing nets.
- Illegal hunting for its meat, eggs and use of crocodile parts for medicinal purposes.
- Poaching for leather products.
- Illegal killing in certain territories and negative attitudes towards the species, which hinder the implementation of conservation measures.
