Whale sharks are the largest species of sharks in the world. Their average size ranges from 18 to 32 feet, but they have been known to reach 40 feet long or more. Whale sharks can reach a weight of approximately 20 tons.
Despite their large size, whale sharks are docile creatures. They are filter feeders, meaning they open their large mouths as they swim and filter out their food using rows of teeth and filter pads, similar to baleen whales. Whale sharks prefer small organisms such as plankton and krill. Whale sharks can be found in the warm, tropical seas around the world.
