The sharks you see on television in Jaws or Discovery’s “Shark Week” are not the friendliest looking creatures. They aren’t exactly an animal you want to find near you while swimming in the ocean. Despite their portrayals (刻画) in movies and popular culture, sharks are complicated, misunderstood creatures that are weaker than they appear. One very common misunderstanding about sharks is their desire to hunt humans. Actually when sharks attack humans, it is because they mistake a human for their normal prey (猎物), seals or dolphins. They don’t seek out humans on purpose. Statistically, you are more likely to be struck by lightning than be bitten by a shark. Sharks are very important to the ocean as they are at the top of the food chain. Some sharks even control the balance of an ecosystem through fear alone. Tiger sharks in Australia help protect seagrass meadows from turtles. Turtles eat the seagrass and without the sharks, will destroy these meadows. When tiger sharks are present though, the turtles are scared away, holding back their appetite for seagrass and protecting its growth. Though sharks have a reputation for being very scary to humans, the sad truth is that they should be scared of humans. The number of sharks in the ocean is steadily dropping. There are a few reasons for this. For one, they mature quite slowly, over several years, and produce relatively few young. For another, overfishing of sharks is happening because more and more people want their fins. About 100 million sharks are killed every year according to National Geographic. Shark fin is a way for people to show off their wealth. Shark fins are also believed to have medicinal benefits, though there is no evidence or proof that they actually do. 1.
