This footage, captured above the appropriately named Shark Bay in Western Australia, shows what happens when 70 sharks come across a whale. It involves rather a lot of blood.
The once-clear waters of the bay fill with plumes of blood as the tiger sharks chow down without mercy on the humpback whale. I can’t work out whether being in one of the nearby boats would provide an amazing spectacle or just pure horror. Maybe a bit of both. [NZ Herald via BBC]
