Deep-sea fish study reveals evolutionary marvels in Earth's hadal zone
At three hundred feet, we are profoundly changed. The pressure at these depths is nine times that of the surface. The organs collapse. The heart beats at a quarter of its normal rate, slower than the rate of a person in a coma. Senses disappear. The brain enters a dream state. At six hundred feet down, the ocean’s pressure—some eighteen times that
