At depths deeper than 8 9 km 5 5 mi sea cucumbers comprise 90 of the total mass of the macrofauna.

Mollusks make up of biomass on ocean floor.

Sea cucumbers can be found in great numbers on the deep seafloor where they often make up the majority of the animal biomass. Inhabiting the ocean floor cover its entire range from shallow coastal environments to the deep sea. The biological pump in its simplest form is the ocean s biologically driven sequestration of carbon from the atmosphere to the ocean interior and seafloor sediments. Some bivalves like the protobranchiates are even found in waters 9 000 m or 29 500 ft deep.

The more advanced cephalopods could be viewed as the most sophisticated invertebrates. Ring in very high biomass comparable to the density of. The sea cucumber is a type of marine life form. Mollusks can be found in all habitats of the ocean.

Cephalopods the most advanced mollusks include octopuses squids cuttlefish and nautiluses. These mollusks have no heads and their bodies consist entirely of a wedge shaped foot gastropods are the most diverse family of mollusks including over 60 000 species of snails and slugs that live in marine freshwater and terrestrial habitats. Sea cucumbers form large herds that move across the bathygraphic features of the ocean hunting food. They are a type of echinoderm so they have an endoskeleton.

The characteristics of the deep sea vary geographically for example the depths of thermoclines insolation and lysoclines depth of carbonate saturation vary latitudinally and between ocean basins rex et al.
