Some of the most important differences between the different types of sharks include size, diet, habitat, and reproductive strategies. Sharks vary greatly in size, with the smallest species being less than 10 cm (4 inches) long and the largest species growing up to 20 meters (66 feet). Diet is another key difference, as some species eat only fish while others feed on a variety of prey items. Habitat also varies greatly among shark species, from open ocean waters to coastal environments. Reproductive strategies can also differ significantly, ranging from live birth to internal fertilization.
