abyssal zone
abyssopelagic

We're out of the abyssal zone and into midwater.

The species occur in the litoral to abyssal zones.

Ipnops are small, slender fish that live close to the ocean floor in the bathyal and abyssal zones.

The abyssal zone is the abyssopelagic layer or pelagic zone.

Bathymetric records suggest that it is a bathyal species with its lower limit in the upper abyssal zone.

The area below the abyssal zone is the sparsely inhabited Hadal zone.

Echinoderms are found at every ocean depth, from the intertidal zone to the abyssal zone.

It is found in the abyssal zone in waters around Australia and New Zealand.

Apart from the record from St Vincent verrilli appears to be a member of the lower abyssal zone fauna.

This species occurs in the Atlantic Ocean in the abyssal zone off Argentina.

A small amount of primary production is generated deep in the abyssal zone around the hydrothermal vents which exist along some mid-oceanic ridges.

A whale fall is the carcass of a cetacean that has fallen into the Bathyal or Abyssal zone on the ocean floor.

Abyssal zone (from 4000m to the ocean floor): no light penetrates to this depth, and some creatures are blind and colourless.

Thaumatichthys axeli lives at a depth of around 3,600 meters (in the abyssal zone), deeper than any other member of the genus Thaumatichthys.

There are at least 12,914 marine species in South Africa, but small bodied species are poorly documented and the abyssal zone is almost completely unexplored.

It has also been argued that Yelovichnus and similar organisms are xenophyophores, large but single-cellular organisms that exist today in the abyssal zone.

The aphotic zone is further divided into additional zones: the bathyal zone, the abyssal zone, and the hadal zone.

Further south still is the Southern Boundary front, which is determined as the point where very dense abyssal zone upwell to within a few hundred meters of the surface.

Deepwater or Deep Water may refer to ocean water in the abyssal zone, hadal zone, or other deep ocean zones.

The majority of species still live in the oceans, from the seashores to the abyssal zone, but some form a significant part of the freshwater fauna and the terrestrial ecosystems.

The United Nations group making preparations for the International Sea-Bed Authority, which would govern the abyssal zones, in the 1980's condemned the consortiums' plans as "wholly illegal."

The abyssal zone covers the abyssal plains between 4,000 and 6,000 m. Lastly, the hadal zone corresponds to the hadalpelagic zone, which is found in oceanic trenches.

These regions are also characterised by continuous cold and lack of nutrients.The abyssal zone has temperatures around 2 C to 3 C (35 F to 37 F) through the large majority of its mass.

Along with the giant squid, deep-sea anglerfish, and black swallower, it is one of the permanent residents found in the abyssal zone and was directly observed on the historic voyage of the bathyscaphe Trieste to the Mariana Trench.

It is one of the most common ichnotaxa throughout the fossil record and is widely distributed in all types of marine sedimentary rocks, including sandstone, shale, limestone and marl that formed in environments ranging from subtidal shelves to the abyssal zone.
