You may wonder why this fish is called a whale shark. Scientists have determined that it is a species of shark, because of its skeleton (composed entirely of cartilage), and its tough, leathery, scaleless skin. People called it a whale shark because of its enormous size (like a whale), not because it's a type of whale. A whale is a mammal; a warm-blooded creature that has lungs and breathes air, gives birth to its young and nurses them with milk produced by mammary glands. A shark is a fish; it "breathes" its oxygen by passing water over its gills.
