The Grey Reef Shark (Carcharhinus amblyrhynchos) has a broad worldwide distribution and can be found throughout the tropical waters of the world. It is a very common shark species of the indo pacific and can often be seen aggregating in particular reef areas. They are often seen near drop offs and reef channels, especially in areas that have strong currents.
This shark predominantly feeds on bony fishes and also on cephalopods and crustaceans. Groups of grey reef sharks (up to 100) have been observed schooling fish up against the edge of a reef before attacking. The shark has litters of 3-6 pups with a gestation period of about 12 months. At birth it is approximately 60 cm and grows to a maximum size of approximately 2.5m. The most distinguishing feature of a grey reef shark is the broad black trailing edge on the caudal fin.
