Scientific Name: Carcharhinus amblyrhynchos
Also called as Long nose Black-tail shark, Grey reef sharks are active night predators, often forming big feeding aggregations that hunt for sleeping fish on the reef. Grey reef sharks have a broad, rounded snout. They are dark grey or bronze-grey above and white below. The caudal fin has a wide, black margin and the undersides of the pectoral and pelvic fins have black tips and margins.
Grey reef sharks are found around coral reefs anywhere between the surface and depths of up to 100m.These are very common in the Central Pacific Ocean. They are common on coral reefs, often in deeper areas near drop-offs to the open sea, in atoll passes and in shallow lagoons adjacent to areas of strong currents.
The grey reef shark feeds on reef fish, squid, octopuses, crabs, lobsters and shrimps. These sharks form daytime schools or aggregations in favored areas. Although active during the day, they are more active nocturnally.
