Benthos (from Ancient Greek βένθος (bénthos) 'the depths [of the sea]'), also known as benthon, is the community of organisms that live on, in, or near the bottom of a sea, river, lake, or stream, also known as the benthic zone. [1]
At the other end of the spectrum, benthos of the deep ocean includes the bottom levels of the oceanic abyssal zone. [7] For information on animals that live in the deeper areas of the oceans see aphotic zone. Generally, these include life forms that tolerate cool temperatures and low oxygen levels, but this depends on the depth of the water. [8]
The BBL is generated by the friction of the water moving over the surface of the substrate, which decrease the water current significantly in this layer. [2] The thickness of this zone is determined by many factors, including the Coriolis force. The benthic organisms and processes in this boundary layer echo the water column above them. [2]
Samples are shaken in an excess of water, the sediment is briefly allowed to settle, and then the meiofauna are filtered off. The second methodology, the flotation technique, works best with finer sediments, where the mass of the sediment particles is close to that of the meiofauna. The best solution for this technique is the colloidal silica ...
Macrobenthos consists of the organisms that live at the bottom of a water column [1] and are visible to the naked eye. [2] In some classification schemes, these organisms are larger than 1 mm; [1] in another, the smallest dimension must be at least 0.5 mm. [3] They include polychaete worms, pelecypods, anthozoans, echinoderms, sponges, ascidians, crustaceans.
