Flora and Fauna
Food crops grown on Bikini and throughout the Marshalls include coconuts, pandanus, papaya, banana, arrowroot, taro, limes, breadfruit, and pumpkin. A wide variety of trees and other plants are also present on the islands. All fruits and vegetables used for the Bikini Atoll dive and sport fishing operation are imported.

Animal life on Bikini and throughout the Marshalls includes small lizards, hermit crabs, coconut crabs, and a wide variety of birds. Pigs, ducks and chickens are raised for food, and dogs and cats are kept as pets.
