Bats are the only land mammals native to Virgin Islands National Park. If you sit outdoors in a quiet place at dusk, you may see bats swooping through the air in pursuit of insects. Bats also pollinate flowers and spread seeds of fruit trees. One type of bat even consumes fish. There are six species of bats in the Virgin Islands.

One of the smallest lizards on St. John is the Dwarf Gecko. This tiny, inch-long reptile is native to the island, while many of the other geckos arrived on sailing ships in the 17th century. Dwarf Geckos feed on insects in the forest during the day, while most other geckos are nocturnal feeders.
