Sharks are some of the most fascinating creatures on Earth. They are apex predators, meaning they are at the top of the food chain. Sharks have been around for over 400 million years, and they have adapted to live in all of the world's oceans. There are over 500 species of sharks, and they come in all shapes and sizes. Some sharks are small, like the dwarf lantern shark, which is only about 6 inches long. Other sharks are large, like the whale shark, which can grow up to 40 feet long. Sharks are predators, and they eat a variety of animals, including fish, squid, and sea turtles. Some sharks are also cannibalistic, and they will eat other sharks.
