Blue Shark

The blue shark is one of the most beautiful and wide-ranging sharks in the ocean, with a slender, elegant body and striking indigo-blue colouration. Found in every ocean, they are the most prolific pelagic shark species. The Azores offer some of the world's best blue shark diving, with open-water encounters in crystal-clear Atlantic water.
