In addition to temperature, they the oceanic area in which they live restricts them. They migrate in a clockwise direction, following ocean currents to seek water ranging in temperature from 7 to 25 C (45 to 77 F).
In this region of the sea, fish tend to move about in large schools, and they can be difficult to catch. In temperate waters the blue shark occurs near the surface. When in warmer waters, these sharks swim in deeper water columns. The geographical range of this abundant species is from latitudes of 60 ºN and 50 ºS!
Blue sharks will live in both warm and cold waters, though they avoid the particularly frigid temperatures in the Arctic and Antarctic. Blue sharks can live in both temperate and tropical waters, which range from 53.6ºF-68 ºF (12-20 ºC). Because of this, blue sharks are found off of every continent except Antarctica. This is perhaps also the reason why they do not do well in the aquarium even if the aquariums are large. Blue sharks are curious, open-ocean predators that live throughout the global ocean, from the tropics to cold temperate waters. Blue sharks, thresher sharks and shortfin mako sharks are just a few examples of species that thrive in the open ocean. The blue shark is an oceanic shark found worldwide in deep temperate and tropical waters from the surface to about 350 meters. Blue sharks are not as violent as other sharks, however, they swim extremely well and very fast.
The Blue Shark (Prionace glauca) is a species in the family Carcharhinidae. Sharks that live in the pelagic zone have adapted to become extremely fast-moving, able to catch their prey with swift movements.
The shortfin mako shark is an especially fast …
The common name comes from the blue color of the skin, unique among the sharks. These sharks are usually found in cool and deep waters.
Blue sharks inhabit cool ocean waters around the globe, as far south as Chile and as far north as Norway. Instead, they prefer temperate and tropical seas.
They spend most of their lives far from the coast and are truly a pelagic species.
In tropical waters the blue shark is more commonly found in deeper waters as it prefers temperatures between 7 and 16 degrees Celsius.
