6000 m; and (v) the hadalopelagic (or ultra abyssal) zone below 6000 m depth. region between the high and low tide of an area. Temperatures here are frigid, and pressures are hundreds of times greater than at the surface of the ocean. The abyss is a distinct zone in the ocean, usually considered to start at a depth of between 3000m and 4000m and extending to 6000m. Abyssal and hadal waters are the reservoirs for broken down organic products that work out downward from the upper areas. 3. 0000640023 00000 n
They all have bristles and appendages. Nevertheless, the animals of the abyssal level tend to have some adaptations that help them cope with their unique environment. The complying diagram reveals the layers of the sea: An abyssal zone is a section of the ocean much more profound than 2,000 m (6,600 feet) and shallower than 6,000 m (20,000 feet). Point out to students that the deepest part of the ocean shown is 11,000 meters (36,100 feet), or approximately 11 kilometers (7 miles) deep. The abyssal zone (Figure 1) is very cold and has very high pressure, high oxygen content, and low nutrient content. They do not have the neural system, internal organs, or sensory organs. they have adapted to have light from their heads. But sadly there . There are many animals living in the Abyssal Zone. All of them have a similar internal structure. Benthic Rover II (BR-II) is an autonomous dual-tracked vehicle that measures bottom water temperature and oxygen concentration, current velocity, and sediment community oxygen . The benthic zone starts at the shore and extends down along the bottom of the lake or ocean. The Abyssal Zone The abyssal zone ranges from 2,000-6,000 meters below sea level. The benthic zone refers to the ecological zone located at the bottom of any marine or freshwater body, such as a river, ocean, lake or pond. All rights reserved.

Organisms of the Benthos and Near-Bottom Animals that reside permanently on the bottom are called benthic organisms. The benthic zone is the area below the pelagic zone, but does not include the very deepest parts of the ocean (see abyssal zone below). Open ocean of any depth, where animals swim or float freely, is called the pelagic zone. The neritic zone is the region of shallow water (200 meters depth) above the continental shelf where light penetrates to the sea floor. A large-area ecosystem with similar characteristics is called a biome 2. xbbbd`b``1@ ,
