Like other fishes, sharks are cold-blooded, have fins, live in the water, and breathe with gills. A shark’s skeleton is made of cartilage. A shark’s fusiform (rounded and tapering at both ends) body shape reduces drag and requires minimum energy to swim. Sharks eat far less than most people imagine.Happy Sharkday
