The blacktip reef shark (Carcharhinus melanopterus) is a species of requiem shark, in the family Carcharhinidae, which can be easily identified by the prominent black tips on its fins (especially on the first dorsal fin and its caudal fin).
Blacktip shark vs.Blacktip sharks are also known as oceanic blacktips because they spend a lot of time in the open ocean, unlike their smaller cousins which, as their name suggests, live in warmer reef waters. The reef-dwellers have black markings on their pelvic fins the oceanic ones lack.
Normally wary of humans, blacktip sharks can become aggressive in the presence of food and have been responsible for a number of attacks on people. This species is of importance to both commercial and recreational fisheries across many parts of its range, with its meat, skin, fins, and liver oil used.
There've been 42 documented attacks on humans by blacktip sharks, but just one resulted in an unprovoked fatality [source: International Shark Attack File]. They're caught by fishermen, who sell their meat for human consumption or to be used as fish meal to feed animals.

The smallest shark, a dwarf lantern shark (Etmopterus perryi) is smaller than a human hand. It's rarely seen and little is known about it, having only been observed a few times off the northern tip of South America at depths between 283–439 meters (928–1,440 feet).
dogfish, (order Squaliformes), any of several small sharks making up an order of chondrichthyian fishes composed of the families Centrophoridae (gulper sharks), Dalatiidae, Echinorhinidae, Etmopteridae, Oxynotidae, Somniosidae, and Squalidae. In North America the name is also used for a freshwater fish, the bowfin.
They are known to frequent bays and shallow waters off beaches, where they're often encountered by humans. “Blacktip sharks are responsible for roughly 20% of the attacks that occur in Florida waters, often striking surfers,†the Florida Museum said.
Because of these characteristics, many experts consider bull sharks to be the most dangerous sharks in the world. Historically, they are joined by their more famous cousins, great whites and tiger sharks, as the three species most likely to attack humans.
Blacktip sharks are found in tropical and subtropical coastal, shelf, and island waters in the Atlantic, where they migrate seasonally between Brazil and Nova Scotia; the Gulf of Mexico and the Caribbean Sea, throughout the Mediterranean, and along the central West coast of Africa.

Leaping Ability and DietBlacktip sharks are sometimes spotted above the water. They leap above the surface, rotate several times, and splash down on their backs. This dramatic display is sometimes part of a stealthy feeding method they use to strike at schools of bony fishes near the water surface.
Biology. It is not uncommon to encounter this shark in the shallows, where its black-tipped fin pokes out of the water. With its nocturnal habits, it feeds on reef fish, small sharks, cephalopods and crustaceans, or even rotting carcasses.
All of the sharks mentioned above are relatively hardy and can be kept by anyone who has experience with saltwater fish or reef aquariums. A 1,000-gallon tank can accommodate Blacktip (Carcharhinus limbatus) or Whitetip (Triaenodon obesus) sharks.
The general rule of thumb is that sharks can cruise at about 5 mph (8 kph)—roughly the same speed as the fastest Olympic swimmer. If you're just a good swimmer, they have you beat. But often they are swimming around at a slower speed of about 1.5 mph (2.4 kph).
Blacktip sharks live in coastal waters off beaches, over coral reefs and in bays and estuaries. They are a migratory species and usually aggregate in small schools segregated by gender.
No, blacktip reef shark cannot be kept as a pet. This is because they grow too big for any home aquarium. Moreover, it is illegal to keep sharks as a pet in many countries to think of owning a Blacktip reef shark as a pet.
Caribbean reef sharks are not an aggressive species and are not considered dangerous to humans unless provoked. However, they are excitable and may make close passes at divers as well as bite in the presence of speared fish.
