On the sea floor, in the benthic zone, food is still scarce and animals have adapted to take advantage of a wide variety of food. The abyssal zone is home to a number of animals such as the deep-sea anglerfish, the black swallower and the giant squid. Because the abyssal zone is so deep, no sunlight can reach it, which means that there is no photosynthesis and no plant light. The zone also has a lower pressure and has a much more stable benthic zone (the ocean floor) compared to other zones. The pelagic zone can be contrasted with the benthic and demersal zones at the bottom of the sea. The abyssal zone supports many species of invertebrates and fishes. But the animals of the abyssal plain tend to have special adaptations to help them cope with their unusual environment. They are typically less than a centimeter long. The Abyss, also called the Abyssopelagic or Abyssal Zone lies in perpetual darkness. It includes the sediment surface and some subsurface layers. This allows them to better absorb light and navigate smoothly.
