It is the most commonly found crocodile of the Indian subcontinent and the only crocodile species found in Iran and Pakistan. In India, it has been reported in 15 states, including Rajasthan, Gujarat, Madhya Pradesh, Uttarakhand, Uttar Pradesh, Odisha, Telangana, Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu. Notable populations are found in the middle Ganga region (Bihar and Jharkhand), the Chambal River (Rajasthan and Madhya Pradesh) and parts of Gujarat.

General Information  
The mugger crocodiles exhibit a polygynous mating system, with breeding typically occurring from February to April. This species is a hole-nesting crocodile, and once a female identifies a suitable nesting site, she often reuses the same location for most of her nests over the years. Approximately one month after mating, female lay around 25-30 eggs per clutch. The average incubation period for the eggs is 55-75 days. The crocodiles can become independent when they are yearlings and large enough to defend themselves. They are most commonly found in freshwater environments such as rivers, lakes, hill streams and village ponds. It prefers slow-moving and shallow water bodies and also thrives in artificial reservoirs, irrigation canals and coastal saltwater lagoons. This crocodile does not migrate seasonally, inhabiting the same locale in wet seasons or dry seasons. Muggers are primarily carnivorous, eating mostly fish, frogs, crustaceans, insects, mammals, birds, and sometimes monkeys and squirrels. They also scavenge on dead animals.   

Threats
- Habitat destruction, fragmentation and transformation.
- Poor water quality, leading to bacterial infections, along with seasonal water level fluctuations, causing significant mortality among hatchlings.
- Drowning in fishing nets.
- Egg predation.
- Use of crocodile parts for medicinal purpose.
