Defined as a fish with a full cartilaginous skeleton and a sleek, streamlined body, a shark can range in size from the two foot pygmy shark, to the colossal 50-foot whale shark.There are more than 250 different species of sharks currently identified, making it one of the most diverse animal genera on the planet.
