'Deadly Underwater 'Death Pool' Discovered'
A 'death pool' has been discovered at the bottom of the Red Sea, 1.1 miles beneath the surface, which instantly kills everything that swims inside it. The pool measures 107,000 square feet and is filled with brine, containing no oxygen, making it deadly to most things that enter it. Predators position themselves on the peripheries of the pool to feed on the unlucky creatures that die after swimming into it. The pool is among the most extreme environments on Earth and is used by some creatures for food.
