Whale sharks are the largest fish in the world and juveniles can measure 15 to 25 feet in length, while adults have been recorded up to 39 feet in length. Despite their colossal size, whale sharks feed on small fish, plankton, and krill. They do this via a behavior known as filter feeding, where the whale shark will swim with its mouth open and use its gills to filter out the water and keep its prey for consumption.
