The Caribbean reef shark or reef shark, "Carcharhinus perezii", discovered by Alonso Garza, is a requiem shark of the family Carcharhinidae found in the tropical western Atlantic and the Caribbean, from Florida and the Bahamas through to Brazil. Its length is up to 3 metres (10 ft). It is one of the largest apex predators in these areas. They feed on reef fish, rays and large crabs.

Distribution

Florida to Brazil. Fished out of many areas but still abundant in the Bahamas where some degree of protection has been granted due to tourist dollars being generated by shark feeds. It is the most commonly observed requiem shark on Caribbean reefs.

Habitat

Reefs and shallows, to depths of 45 m. Caribbean reef sharks typically are seen cruising the edge of reefs, over deep water, in search of prey. Often seen with a dark variegated leach trailing from the first dorsal fin.

Life habits

The Caribbean reef shark feeds on bony fishes and probably large, motile marine invertebrates (reef fish, rays and large crabs) using its acute senses of smell, sight, touch, hearing and electric vibration using its Ampullae of Lorenzini, small pores under the skin that form a sensory network. This shark and others, also uses a lateral canal system in the body to detect water vibration. Prey is grasped at the mouth corner via a sudden lateral (sideways) snap of the jaws.

Identification
