The whale shark is the largest living fish. It can reach a length of at least 40 feet (12 meters). Whale sharks are dark gray or reddish-brown in color. They have large white spots on the upper side of the body and are pale white or yellow underneath. Whale sharks have wide, flat heads and a wide mouth. Adult whale sharks have more than 300 rows of tiny, hooked teeth.
Female whale sharks lay eggs the size of footballs. The newly hatched young are about 2 to 3 feet (60 to 90 centimeters) long.
Whale sharks are found in tropical oceans throughout the world. Scientists know little about these sharks because they are so rare.
Whale sharks are harmless to people. However, boats sometimes accidentally hit large whale sharks, causing damage to both the shark and the boat.
