Explain the biological life cycle of nekton and the differences between it and benthic organisms. Anglerfish are one of the organisms found in the abyssal zone. When these eruptions persist long enough, mounts continue to grow, extending beyond the abyss into shallower waters, even creating volcanic islands when they break the waters surface. The bottom at these depths accounts for about one-third of the planets seafloor. Entire communities of animals and microbes adapted to the high-pressure environment thrive in the dark depths, relying on limited carbon input from land or whale falls. At the deepest point in the ocean lives a fish that is pink, slimy, and looks a bit like an oversized tadpole, up to a foot long.

Some organisms can live in this zone by using chemosynthesis, which is energy that is produced by chemical reactions. It lives on a sea floor, on a depth from 2 950 to 15 400 feet. Several abyssal animals are bioluminescent, which implies they can generate their light. Thanks to the life on great depth, tripod fish is still protected from negative human activities. Read our Privacy Policy. This project is not without challenges, given the remote location and extreme topography and pressures found in ocean trenches. One of their primary benefits is their ability to reconfigure their mission on the fly if they encounter unexpected issues. In most areas, the ocean floor lies 4,000 to 6,000 meters (13,000 to 20,000 feet) below the surface, but deep ocean trenches can extend this depth to 11,000 meters (36,000 feet).
