The primary shark predators of bottlenose dolphins are the bull shark, tiger shark, dusky shark and great white shark. Shark bite scars on dolphins indicate that sharks typically attempt to ambush dolphins from behind and below. Some researchers think that shark attacks may not even be an attempt to eat a dolphin.
In the wild, bottlenose dolphins inhabit the temperate and tropical oceans around the world, with coastal populations entering into bays, estuaries, and river mouths. Like the name âbottlenoseâ suggests, this species of dolphin has a short, stubby beak. Its sleek, conical body varies in color from a light to slate grey on the upper body to a pale to pinkish grey on the bottom part. Bottlenose dolphins measure around 2-4 m (6-12 ft.) long and weigh 135-650 kg (300 â 1400 lbs.). Males are significantly larger than females.
