The region also has a much higher concentration of nutrient salts, such as nitrogen, phosphorus, and silica, as a result of the large amount of dead organic material that drifts down from the above ocean zones and decomposes. In addition to sharks, invertebrates such as squid, shrimp, sea spiders, sea stars, and other crustaceans are also included. The Abyssal zone alone covers around 83% of the total area of the ocean! Because water pressure increases one atmosphere every 33 feet in depth, animals in the abyssal zone must be able to withstand tremendous amounts of pressure. They are: 1. This zone is characterized by a relative lack of life. The bathypelagic is much larger than the mesopelagic and 15 times the size of the epipelagic. Hadalpelagic Zone Even at the very bottom, life exists. Invertebrates like jellyfish, squids, octopus and krill are . A habitat is an environment where an organism lives throughout the year or for shorter periods of time to find a mate. The water temperature is constantly near freezing, and only a few creatures can be found at these crushing depths.

This layer of the ocean is incredibly deep and doesn't get any sunlight from the surface. Do any animals live in the abyssal zone? Many of these bacteria, for example, convert hydrogen sulfide to sulfate and store the energy extracted from this reaction as chemical energy by synthesizing carbon-based compounds. This lack of light is a primary influence, along with water pressure, on the creatures that live there. Brennan holds a Bachelor of Science in biology from the University of California, San Diego. This zone is characterized by highly uniform environmental conditions, as reflected in the different types of life that inhabit it. Grenadiers, sometimes known as rattails, are a group of marine fish from the family Macrouridae that inhabit the deep-sea from 200 m to 7000 m. The mesopelagic zone (or middle open ocean) stretches from the bottom of the epipelagic down to the point where sunlight cannot reach. You will find sharks, tuna, jellyfish, and sea turtles. These bacteria are food for large tube worms that also inhabit the vents. You cannot download interactives. The one exception to this is found around rifts where tectonic plates are spreading apart and new seafloor is being formed. Colder temperatures, food scarcity, reduced predation pressure, and increased dissolved oxygen concentrations in the deep sea are a few explanations for this type of gigantism.
