| | Requiem Sharks | Carcharhinidae (Site not responding. Last check: ) |
 | | The family Carcharhinidae, or requiem sharks, include many of the familiar "shark-like" sharks, such as the fltip, whitetip and silvertip sharks, tiger shark, lemon shark, blue shark, bull shark, gray reef shark, Caribbean reef shark, bronze whaler, silky shark, sandbar shark, and Galapagos shark. |
 | | Ground sharks have five gill slits, a long mouth that reaches behind the eyes, and anal fin, two dorsal fins with no spines, a spiral or scroll valve in the intestine, and a unique semi-transparent "third eyelid" called a nictitating membrane, which comes up from beneath to protect the eye while feeding. |
 | | Ground sharks inhabit both tropical and cold seas, and are found in fresh water as well. |
