Manta Ray Tuna Spotted Eagle Fish As a form of adaptation, the retinas of these carnivores are sensitive only to the color blue, which is the color that The Greatest Depth The bathyscape Trieste holds the record for the maximum depth achieved by any submarine vehicle. In 1960 it descended into the Mariana Trench to 36,000 feet (10,911 m) below sea level and withstood the tremendous pressure at that depth.

Lava from the volcanoes cools quickly, solidifies, and forms chimneys around which an explosion of microscopic (bacteria) and macroscopic (infaunal worms) life occurs that can serve as food for various species of fish.
