The basking shark is the second largest living fish after the whale shark and can be found in all the world’s temperate oceans. Like the whale shark and mega-mouth shark, they feed on plankton and are a slow-moving filter feeder. While they can appear threatening due to their size and gaping mouth, they are docile and pose no threat to humans. Satellite tracking shows that they move thousands of kilometers in the winter in search of plankton blooms. They are social animals that form sex-segregated schools that, while typically small, may reach around 100 individuals.
