Order Carcharhiniformes

The Order Carcharhiniformes, commonly known as the Groundshark Order, is the largest order of sharks. It has over 250 species. Many of the sharks in this order are "famous" sharks, such as the great hammerhead, the tiger shark, and the bull shark.

All groundsharks have a nictitating membrane to protect their eyes. This is one of the few common characteristics that all groundsharks share.
