Grey Reef Shark (Carcharhinus amblyrhynchos) – A Powerful Predator of the Reef

The grey reef shark (Carcharhinus amblyrhynchos) is a sleek, fast-swimming predator commonly found in warm tropical waters of the Indian and Pacific Oceans. It inhabits coral reefs, lagoons, and drop-offs, with populations spanning from the Red Sea and the coasts of Africa to Australia, Southeast Asia, and the Pacific islands.

Size and Appearance

Grey reef sharks typically reach 6.5 feet (2 meters) in length and weigh around 75 pounds (34 kg). They have a streamlined body with a broad, rounded snout, sharp serrated teeth, and large eyes adapted for hunting in dim reef environments. Their grey upper body and white underside provide effective camouflage, while a distinct black margin on the tail and dorsal fin helps distinguish them from similar reef shark species.

Biology and Behavior

Grey reef sharks are opportunistic hunters, feeding on bony fish, squid, crustaceans, and small rays. They are active during both day and night, often patrolling reef edges in small groups. Known for their territorial nature, these sharks can be bold around divers and have been observed exhibiting an arched-back threat display when feeling threatened.
