SHARKS Mention the word “shark” to someone on the beach and you are bound to get a reaction. Sharks have been the most feared predator of the ocean. Sharks are fish. They have been around since the time of dinosaurs. They can be found in oceans all over the world, and they have also been found in some rivers and lakes. One difference between most other fish and a shark is that most fish have bones and a shark has cartilage. Cartilage is tough, but it is not as strong as bone. Another different is that the shark is only able to swim forward, while most fish can swim forwards and backwards. Fish also generally have slippery scales, while a shark has rough scales that feel like sandpaper. There are many different types of shark. In fact, there are about 368 different types. The differences include color, habitat, behavior, and size. Sharks are also known for their very sharp teeth. They do not use their teeth to chew their food. Instead they swallow large chunks of food. They have five rows of teeth. If a tooth is broken, it is replaced by another tooth. Sharks are carnivores, meaning that they eat meat. Sharks do not normally attack people. It seems like sharks attack people a lot, but the chances of getting stung by a bee or getting hit by lighting are greater.
