Whale sharks are often called the “gentle giants” of the sea – and for good reason. Though they are the largest fish on Earth, with some individuals growing to the size of a school bus, they snack exclusively on small prey such as plankton, crustaceans and squid.
Thanks in part to their remarkable size and indifference toward humans, snorkelers and divers flock to warm waters around the world to swim alongside these friendly sharks (yes, they’re technically sharks, and therefore fish). Mexico and the Philippines – two places where Oceana fights to protect ocean habitats and the marine life that dwell there – see the highest numbers of known whale sharks of any coastal country, respectively.
