The most vivid blue in the ocean. Long pectorals, indigo flanks, pelagic and rarely seen on reef.
Blue sharks have the longest pectoral fins of any shark relative to body size and a striking colour: deep indigo above, electric blue flanks, white below. They're transoceanic migrators, with tagged individuals crossing the Atlantic in a single season.
They almost never visit coral reefs. Most recreational encounters happen on chartered blue-water trips off the Azores, Cape Cod or South Africa. From our destinations, the closest reliable encounter is Egypt's Red Sea liveaboards on the open-water transits between sites.
Despite their pelagic life they're approachable: slow circling around bait, curious about divers, easy to photograph in blue water. Tens of millions are killed annually for the shark-fin trade, but legal protections are slowly improving.
