Jamaica's fauna, typical of the Caribbean, includes highly diversified wildlife with many endemic species. As with other oceanic islands, land mammals are mostly several species of bats of which at least three endemic species are found only in Cockpit Country, one of which is at-risk. Other species of bat include the fig-eating and hairy-tailed bats. The only non-bat native mammal extant in Jamaica is the Jamaican hutia, locally known as the coney. Introduced mammals such as wild boar and the small Asian mongoose are also common. Jamaica is also home to about 50 species of reptiles, the largest of which is the American crocodile; however, it is only present within the Black River and a few other areas. Lizards such as anoles, iguanas and snakes such as racers and the Jamaican boa (the largest snake on the island), are common in areas such as the Cockpit Country. None of Jamaica's eight species of native snakes is venomous.
