Blue shark

Blue sharks are the most wide-ranging pelagic shark in the Atlantic and converge on Princess Alice Bank from June through September, following the same upwelling currents that concentrate their prey — squid and small schooling fish. Slender, long-finned and extraordinarily graceful, blue sharks are known for close-approach behaviour with divers and are the quintessential mid-Atlantic big-animal encounter. Despite being the most commercially caught shark in the world, they remain relatively abundant at remote Atlantic seamounts.
