With a mouthful of teeth, shark’s do not seem to need much protection.
However, sharks have little or no protection from humans who hunt them for almost every part of their body to make leather, jewelry, soup, cosmetics, and other items.

Sharks are also hunted for sport and many are inadvertently caught in fishing nets or in nets placed to protect humans. Sharks have a great deal to fear from humans. Compared to the 10-15 people killed by sharks each year; over 100 million sharks perish at the hands of humans annually and many populations may face extinction. Sharks are killed for many reasons, including fear;
However; the product that drives the market are the fins. After drying, collagen fibers are extracted from them, cleaned, and processed to make 'shark fin soup'. In spite of the fact that these fibers have little flavor or nutritional value, the soup is considered a delicacy, and may sell in the Orient for more than $100 ( £65) a bowl.

Often the fins are sliced off when the shark is still alive and the mutilated shark is dumped back into the water to die a slow and agonizing death.
