They retain several rows of teeth, which roll outward to replace those that are lost. The whale shark, on the other hand, is a kinder, gentler shark. As a filter feeder, they feed primarily on plankton and small fish. They have distinctive spotted markings on their fins and dorsal sides. They are the largest species of fish alive today.
Whale sharks live in tropical and temperate seas.
They pose little or no risk to humans. In fact, whale sharks are considered a particular treat to divers, since they are impressive in size but are slow-moving and not aggressive.
