In fact, they are 100 times more sensitive to light than the human eye. When it comes to fish that do have eyes, their eyesight is extremely sensitive. Abyssal fish with no eyes will need to rely on other senses in order to locate prey, mate and avoid predators. Eyes: some abyssal species have enormous eyes, while others don't have eyes at all.Others, have huge sharp teeth that don't fit in their mouth when closed. Some species seem to be made up of merely a head and a large jaw. In fact, sometimes their prey are larger than them. The devlopment of their mouths and stomachs allow them to feed on larger prey. This is an adaption to the lack of food sources. In fact, many have larger mouths than their bodies. Mouth: Many abyssal fish species have extremely large mouths in comparison to their bodies.The temperature of the abyssal zone is very cold and has a quite high hydrostatic pressure. ![]() These fish also have a very soft and flexible body that allows them to float around the deep sea. The abyssal zone is located between 3,000 and 6,000 meters deep, below the area known as bathypelagic and hadopelagic. Many abyssal fish have bioluminescence which allows them to produce light from their organism. Benthic plants include macrophytic angiosperms like mangrove trees, marshgrasses, and seagrasses. These are the supralittoral, littoral, sublittoral, bathyal, abyssal, and hadal zones. This helps them blend into their environmental that is in perpetual darkness. The benthic environment is divided into a number of distinctive ecological zones based on depth, seafloor topography, and vertical gradients of physical parameters. The Abyssal zone’s average depth is 13,000 feet, but the deepest known point is around 36,000 feet deep. An abyssal zone, also known as an abyssopelagic zone, is the deep part of the ocean below 2000 m. Body: these fish don't have bright or flashy colors, many lack any color and seem to be transparent. The zone is home to an astounding range of animals, including many deep-water corals, tube worms, crabs, sponges, sea squirts, and much more.Temperatures here are frigid and pressures are hundreds of times greater than those at the oceans surface. Another reason for their weak bones is the fact that they cannot receive the nutrients and minerals, such as vitamin D or calcium, due to the lack of sun and the specific water components. The region of the ocean that lies between 3,000 and 6,000 meters (or 9,800 and 19,700 feet) below the oceans surface is called the abyssal zone. This is because there are only weak currents in the abyss zone. Skeleton: abyssal fish have weak bones as they have no need for stronger bones.As previously mentioned, these fish share certain characteristics that allow them to survive in the extreme conditions of the abyssal zone.
