People ask


Where do sharks live the most?

Rocky coastlines.


You may not think of a rough, rocky coast as the most hospitable environment for sharks, but a diverse variety of species live beneath the surface, which means a steady food supply – which is why spiny dogfish sharks, white sharks, and scalloped hammerhead sharks are attracted to these regions

Sharks inhabit all five of the world's oceans – Atlantic, Pacific, Indian, Arctic and Southern – and are found in shallow coastal waters to the deepest, darkest and coldest parts of the open seas. They are common down to depths of around 2,000m but it is incredibly rare to find sharks below 3,000m
