Despite their name, whale sharks are part of the shark family: Rhincodontidae, so they are more sharks than whales. They are cold blooded, not mammals. They only resemble whales in size and in feeding. Whale sharks have wide mouths with small baleen teeth they use to filter plankton. That’s why they can be seen close to the surface of the warmest tropical waters in the world: from Honduras to the Maldives.
