Beschreibung:

Here is anohther shark species in the Ripley's Aquarium of Canada- the Black-tip Reef Shark, so called due to the back tips of it's dorsal and tail fins. The blacktip reef shark (Carcharhinus melanopterus) is among the most abundant sharks inhabiting the tropical coral reefs of the Indian and Pacific Oceans, this species prefers shallow, inshore waters. Its exposed first dorsal fin is a common sight in the region. Most black-tip reef sharks are found over reef ledges and sandy flats, though they have also been known to enter brackish and freshwater environments. This species typically attains a length of around 5.2 ft.Blacktip reef sharks have extremely small home ranges and exhibit strong site fidelity, remaining within the same local area for up to several years at a time. They are active predators of small bony fishes, cephalopods, and crustaceans, and have also been known to feed on sea snakes and seabirds. Under most circumstances, the blacktip reef shark has a timid demeanor and is easily frightened away by swimmers. However, its inshore habitat preferences bring it into frequent contact with humans, and thus it is regarded as potentially dangerous. As of early 2009, 11 unprovoked attacks and 21 attacks total (none fatal) were listed on the International Shark Attack File that are attributable to the blacktip reef shark. Most attacks involve sharks biting the legs or feet of waders, apparently mistaking them for their natural prey, and do not result in serious injury (Toronto, Canada, Nov.2015)
