For over 100,000,000 years, sharks have roamed the seas. There are more than 400 species alive today. Each species shares similar traits, but each is distinct and remarkable. All sharks are cartilaginous fishes, with five to seven gill slits on each side of their head. Sharks range in size from a few inches long to the size of a city bus. They have paired nostrils and fins. All have some sort of natural camoflauge. All sharks have the five senses common to humans and most other animals, but sharks also have
electrosensitivity through their specialized organs, ampullae of Lorenzi, which are located on the snout.
Sharks reproduce sexually via internal fertilization. Roughly half of all sharks lay eggs, while the other half give birth to live young. Their lifespans, like many things about sharks, are unknown. Their behavior and morphology vary greatly depending on the shark species. Select a species from the following list for more information and multimedia...
