Sharks are a meat-eating fish and one of the most feared sea animals. These fish live in oceans throughout the world but are most common in warm seas. Sharks vary greatly in size and habits. Whale sharks are the largest kind of shark. They weigh up to 15 tons, more than twice as much as an African elephant. They can grow up to 60 feet long. The smallest sharks may measure only 4 inches long and weigh less than 1 ounce. Some kinds of sharks are found near the surfaces, and some live in the depths of the ocean. Sharks live in coastly water and some out at sea.

Sharks are one of nature's most efficient predators. Some sharks can smell a scent that is more than one mile away.

Most sharks hunt other vertebrates, some species of sharks also eat sea lions, sea turtles, sea birds, and dolphins.
