Beauty Of Animal | Blacktip Shark | The blacktip shark (Carcharhinus limbatus) is a species of requiem shark, family Carcharhinidae. It is common to coastal tropical and subtropical waters around the world, including brackish habitats. Genetic analyses have revealed substantial variation within this species, with populations from the western Atlantic Ocean isolated and distinct from those in the rest of its range. The blacktip shark has a stout, fusiform body with a pointed snout, long gill slits, and no ridge between the dorsal fins. Most individuals have black tips or edges on the pectoral, dorsal, pelvic, and caudal fins. It usually attains a length of 1.5 m (4.9 ft).
Black tipsharks can be foundin bothinshoreand offshore, but theytend to staynear the coastat depths of30mor lessexternal link. Theyare often seennear river mouths, bays andmangroves, although they do not penetratedeep intofresh water.Black tipsharkis found intropical and subtropicalcoastal, shelf and the watersof the islandsin the Atlantic,where they migrateseasonallybetween Brazil andNova Scotiaand theGulf of Mexico andCaribbean Sea,toacross the Mediterranean,and alongthe central coast ofWestAfrica.In the Pacificthey range fromsouthern Californiato Peru, including the Sea of Cortez, the Galapagos Islands, Hawaii,Tahitiand otherSouth Pacific islands, on the north coastof Australia.In the Indian Ocean, they range fromSouth Africaand Madagascarto the Red Sea, Persian Gulf, across the coastof India,and Eastto the coastof China.
Blacktip shark are strong sharks with a moderately long and pointed snout. The first dorsal fin is slightly posterior to the pectoral fins high on the mid section of the body and has a narrow, pointed tip. This species does not have an inter dorsal ridge. They have dark gray or blue to brown on the dorsal side with a white ventral side and a white band across the flank. The pectoral fins, first and second dorsal fins, pelvic fins, and lower caudal lobe are black tipped, although the dark coloring tends to fade with age. The anal fins of the Blacktip sharp do not have black tips, unlike the similar Spinner shark, which often develops black tips on the anal fin as they mature. Blacktip shark gets its name from its distinctive black markings on the tips of its fins. It is also known as Blackfin, Small blacktip, and Spot-fin ground shark.
Blacktip shark feeds on small schooling fishes such as herring, sardines, menhaden, mullet, and anchovies, but also eats catfishes, groupers, jacks, snook, porgies, grunts,croakers, flatfishes, triggerfish, and porcupine fish. They are known to feed on other elasmobranch species such as dogfish, sharpnose sharks, young dusky sharks, skates, and stingrays. Crustaceans and squids are also prey for blacktip sharks. Like the Spinner shark, Blacktip shark have been observed leaping and spinning out of the water, which is likely a feeding behavior. Blacktips attack schools from below at high speed while snapping their jaws to capture prey. The tiger shark preys on young blacktip sharks.
Blacktip sharks in the Caribbean are a popular tourist attraction during shark feeding dives along with other species such as Caribbean reef sharks. Blacktip sharks is fished commercially by longlines off the southeast coast of the US, and caught as bycatch in fixed bottom nets and in shrimp trawls. The flesh is sold for human consumption and used for fish meal, and the fins are sold for shark fin soup in Asian markets, a product that is decimating shark populations worldwide. The skin is also used for leather.
