慶良間群島
Around 360 fish species and 1,640 invertebrate species (including hermatypic corals) and 220 seaweed species have been recorded in the Kerama Islands, but many groups of organisms have not yet been surveyed. Green turtles, loggerheads, and hawksbill turtle lay eggs on the beaches in summer. Humpback whales (Megaptera novaeangliae) are regular visitors in January to April and use the Kerama Islands as their breeding ground.
