I hope that you … Black tip reef sharks feed on smaller fish that populate the coral reef, like small rays, crabs and lobsters. Mating season for this species of shark is usually between the months November and March (Mourier and Planes 2013). Blacktips are obligate ram ventilators, which means that they have to keep swimming to push oxygen-carrying water over their gills to breathe. Their only predators are larger sharks, like tiger sharks and grey reef sharks, when the blacktip is still small. Blacktip Reef Shark (Carcharhinus melanopterus) The Blacktip Reef Shark is a shark of tropical and warm temperate seas. Reef shark assemblages include both reef-dependent species such as grey reef (Carcharhinus amblyrhynchos), black tip (Carcharhinus melanopterus) and white tip reef sharks (Triaenodon obesus), and more transient but reef-associated species such as silvertip (Carcharhinus albimarginatus), tiger (Galeocerdo cuvier) and hammerhead sharks (Sphyrna spp.) The Blacktip Reef Shark is found in warm, shallow water near coral reefs in the Indo-Pacific and Mediterranean Sea with depths of up to 80 meters (262 feet).
