Yes, sharks are a type of cartilaginous fish that live in oceans and seas all around the world. They have a streamlined body shape and powerful jaws filled with rows of sharp teeth that they use to hunt and eat a variety of prey, including fish, squid, and even other sharks. There are over 500 different species of sharks, ranging in size from the tiny dwarf lanternshark, which is only a few inches long, to the massive whale shark, which can grow up to 40 feet in length. Despite their reputation as fearsome predators, most sharks are actually quite shy and will typically avoid contact with humans if possible. However, some species, such as the great white shark, have been known to attack humans under certain circumstances.
