The largest non-cetacean animal in the world, this huge dappled-grey fish can reach around 14 to 20 metres in length. Whale Sharks present no danger to humans and are filter feeders, with a diet that includes plankton, krill, fish eggs and copepods. Whale Sharks are found in all tropical and warm seas in both coastal and ocean habitats. Western Australia is one of the best places in the world to observe these giants of the deep, which from March to August congregate to feed along the UNESCO World Heritage-listed Ningaloo Reef.
