...and finally, rounding out the biology lesson for today... 3. the Oceanic WhiteTip Shark - Carcharhinus longimanus - a moderately-sized shark, up to about 4m in length, it is nonetheless one of the most dangerous of all. It has no fear of humans, and is utterly unpredictable. Recognizable by its huge dorsal and pectoral fins, this denizen of the open tropical and sub-tropical seas is the shark most likely to appear at an accident scene. Do not confuse it with the smaller, less dangerous WhiteTip Reef Shark. An opportunistic feeder, the Oceanic WhiteTip eats mainly fish, swimming seabirds, and seaturtles - oh, and 'carrion.' Females give live birth to litters of up to 15 pups.
