Mollusks Make Up Of Biomass On Ocean Floor

The sea cucumber is a type of marine life form.

Mollusks make up of biomass on ocean floor.

They are a type of echinoderm so they have an endoskeleton. They also have various forms of connective tissues that comprise them. 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. Sea cucumbers can be found in great numbers on the deep seafloor where they often make up the majority of the animal biomass.

Sea cucumbers form large herds that move across the bathygraphic features of the ocean hunting food. Cephalopods the most advanced mollusks include octopuses squids cuttlefish and nautiluses. At depths deeper than 8 9 km 5 5 mi sea cucumbers comprise 90 of the total mass of the macrofauna. Some bivalves like the protobranchiates are even found in waters 9 000 m or 29 500 ft deep.

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. 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 cucumber facts and information introduction to sea cucumber. It is the part of the oceanic carbon cycle responsible for the cycling of organic matter formed mainly by phytoplankton during photosynthesis soft tissue pump as well as the cycling of calcium carbonate caco 3 formed into.

Mollusks inhabiting the ocean floor cover its. Ring in very high biomass comparable to the density of. The more advanced cephalopods could be viewed as the most sophisticated invertebrates.
