Deep sea divers

Emperor penguins sometimes dive to depths of 265 m.

In 1987 a leatherback turtle fitted with a depth-gauge reached a depth of 1,200 m.

Sperm whales regularly dive to 1,200 m and experts think they may sometimes go down to twice this depth.

Fish called brotulids are the deepest-living vertebrate animals. They have been found in deep-sea trenches at 8,300 m – that is almost as deep as mount Everest is high.
