Sharks are fish that live mostly in the ocean. They have strong, streamlined bodies that help them move quickly through the water. Unlike many fish, a shark’s skeleton is made of cartilage, which is lighter and more flexible than bone.
· Sharks have rough skin covered in tiny tooth-like scales called dermal denticles.
· Most sharks have several fins, including dorsal fins on the back, pectoral fins on the sides, and a tail fin for pushing forward.
· Sharks breathe through gills, which take oxygen from the water.
· Their teeth are often sharp and are replaced many times during their lives.
· Many sharks have a strong sense of smell and can detect movement in the water.
· A shark’s tongue is called a basihyal. It is made of cartilage and usually cannot move very much. Some shakes use it to rip the flesh off their prey.
These body features help sharks find food, stay balanced, swim efficiently, and survive as ocean predators.
