Idea # 166 – Dive with Blue Sharks in the Azores

The blue shark, also called blue skin (Prionace glauca) is a species of pelagic sharks. This shark is characterized by its tapered shape and the bluish tinge to the top of his body. Its size is usually about 2 meters and maximum size observed is 4 meters . It is very present into temperate to tropical oceans, between 350 meters deep and the surface. It evolves in between 7 °C and 16 °C water temperatures, but supports also well slightly hotter waters, over 20 °C. Solitary animal, but being able to group together temporarily in same-sex bench, the blue shark of the Atlantic Ocean migrates annually from the Caribbean to the coast of North America, then to Europe and finally to Africa before, returning to its starting point. These peculiarities make it easily observable in the Azores Archipelago, which gather the environmental and geographical parameters necessary for its observation.

The blue shark is considered as averagely dangerous, because being only rarely for the contact of the man, he can attack him by fear or out of curiosity. The reported attacks remain nevertheless rare.

Where is it?

Pico Island, Azores Archipelago, Portugal.
