Mongooses live in Asia, Africa, and southern Europe, as well as some Caribbean islands, where they are introduced species.
Mongooses mostly feed on insects, crabs, earthworms, lizards, snakes, chickens, and rodents. However, they also eat eggs and carrion. Some species, such as the Indian Mongoose, are popularly used to fight and kill venomous snakes, even king cobras.
Some species of mongoose are fairly intelligent and can be taught simple tricks, which has led to a number of them being domesticated, often kept as pets to control vermin.
