What types of animals live in the oceanic zone? Mesopelagic animals play an important role in the global carbon cycle and ocean's food chain. By this definition, all of the deepest parts of the ocean conclude in the hadopelagic. She is also certified in secondary special education, biology, and physics in Massachusetts. Because of the lack of light, there are no plants producing oxygen, which comes mostly from ice that has melted long ago in the polar regions. The cold climate there produces sea ice and residual cold brine. 1145 17th Street NW 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.

Anglerfish, for example, physically attach themselves to a female, using her blood as food and fertilizing her eggs in return. The temperature is constant, at just above freezing. This activity targets the following skills: The resources are also available at the top of the page. Immediately following the epipelagic zone is the mesopelagic zone, where sunlight is very faint and you can find creatures that glow in the dark or are bioluminescent. If no button appears, you cannot download or save the media. Generally speaking the deep end of the mesopelagic zone is approximately 1000 m (3300 feet) deep.

Open Ocean - Oceana The brine sinks due to its high density and flows slowly toward the Equator along the bottom. The abyssal zone is a strange, harsh world that seems ill-adapted to support life. These include the epipelagic zone (sunlight zone), mesopelagic zone (twilight zone), bathypelagic zone (midnight zone), abyssopelagic zone (abyssal zone), and the hadalpelagic zone. In addition, due to the amount of water covering the abyssal zone, the pressure is extreme, between 200 and 600 times that of the surface.

It is the pitch-black bottom layer of the ocean. Abyssopelagic Zone - The next layer is called the abyssopelagic zone, also known as the abyssal zone or simply as the abyss. There are no plants in the abyssal zone because it is too deep for sunlight to penetrate, and the sunlight is necessary for plants to grow. Below the epipelagic zone is the mesopelagic zone, extending from 200 meters (660 feet) to 1,000 meters (3,300 feet). We will discuss this in more detail as we progress through this article.
