In general, more suspension feeders, such as corals, live on hills and seamounts than on the adjacent plain. It is the lowest zone not including the hadal zone, which is the water located in the ocean's trenches. Abundance and diversity decrease with increased water depth and distance from the shoreline, a result of dwindling food availability, increased pressure, and decreasing water temperatures. Abyssal Mammoths - Layer 13 6. Because the abyssal zone is so deep, no sunlight can reach it, which means that there is no photosynthesis and no plant light.

In the Northern Hemisphere, the surface air moving northeast from 30 to 60 degrees is moist and encounters cold air moving south to form a stormy region. Deep sea dredges have collected specimens of unusual-looking fish, worms, and clam-like creatures from these depths. The plain is generally 13,000 to 20,000 ft (4,000 to 6,000 m), extending seaward from the base of a continental slope or from the seaward edge of an oceanic trench to the midocean ridge. Abyssal fauna, though very sparse and embracing relatively few species, include representatives of all major marine invertebrate phyla and several kinds of fish, all adapted to an environment marked by no diurnal or seasonal changes, high pressures, darkness, calm water, and soft sediment bottoms. In other regions, overall biomass has been found to be higher on seamounts and abyssal hills than on the plain.

Abyssal plains are the vast, flat, sediment-covered areas of the deep ocean floor. They are the flattest, most featureless areas on the Earth, and have a slope of less than one foot of elevation difference for each thousand feet of distance. The lack of features is due to a thick blanket of sediment that covers most of the surface. A. The abyssal plains are so deep that scientists don't know much about the life forms that live there.
