The island is known for its ecosystem; the Indonesian government has declared 60 square kilometres (23 sq mi) of inland and sea around the island as a wildlife protection area. A rare megamouth shark species was found on shore and the island is the only habitat for the threatened toad, Duttaphrynus valhallae (formerly Bufo valhallae). Coral reef areas around the island are known for their large variety of fish species.
