Without leopard sharks and other sharks, their prey would over populate the ocean. Actually, sharks help the aquatic food chain by doing this. The leopard shark eats tiny fish, mollusks, and arthopods. The predators of the leopard shark are of course humans, orcas, and dolphins. Covering the skin of the leopard shark are scales, which cover all fish.
Sharks have a special kind of scales called denticle.
Denticle are similar to the shark's teeth. The denticle are wedged together to cover the skin of the leopard shark. The leopard shark is consistently being hunted for its meat. That statement is true. About ten people are killed by sharks.
