The fauna of the United States Virgin Islands consists of 144 species of birds, 22 species of mammals, 302 species of fish and 7 species of amphibians.[1] The animals include numerous native species of tropical birds, fish, and land reptiles as well as sea mammals. The only native land mammals are six species of native bats: the greater bulldog bat, Antillean fruit-eating bat, red fruit bat, Brazilian free-tailed bat, velvety free-tailed bat and the Jamaican fruit bat. Some of the nonnative land mammals roaming the islands are the white-tailed deer, small Asian mongoose, goats, feral donkeys, rats, mice, sheep, hogs, dogs and cats.[2]: 302
Sea mammals includes numerous species of whales, dolphins, orcas, and manatees. The islands' only species of seal, the Caribbean monk seal, was deemed extinct in the early 1950s. Virgin Islands National Park and the Virgin Islands Coral Reef National Monument are the two largest among many refugees for numerous species of wildlife. Some of the currently endangered animals includes the West Indian manatee, Virgin Islands tree boa (Epicrates monensis monensis), Saint Croix ground lizard, and the green sea turtle.[3]
