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]
Benthos are the organisms that live in the benthic zone, and are different from those elsewhere in the water column; even within the benthic zone variations in such factors as light penetration, temperature and salinity give rise to distinct differences, delineated vertically, in the groups of organisms supported. [10]
Nekton are the aggregate of actively swimming organisms which are able to move independently of water currents, such as shrimps, forage fish and sharks. As a rule of thumb, plankton are small and, if they swim at all, do so at biologically low Reynolds numbers (0.001 to 10), where the viscous behaviour of water dominates and reversible flows ...
English sources preferred: Do check to see if an English-language citation is available that is the equivalent of the foreign-language citation (for example an authorized translation), since that's easier for readers to verify. If you do find one, you don't need to include the foreign-language citation.
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.
Filamentous cyanobacteria growing on an underwater surface. Phytobenthos (/. f aɪ t oʊ ˈ b ɛ n θ ɒ s /) (from Greek φυτόν (phyton, meaning "plants") and βένθος (benthos, meaning "depths") are autotrophic organisms found attached to bottom surfaces of aquatic environments, such as rocks, sediments, or even other organisms.
Neuston, also called pleuston, are organisms that live at the surface of a body of water, such as an ocean, estuary, lake, river, wetland or pond.Neuston can live on top of the water surface or submersed just below the water surface.
He estimates that the theory and practice of English-language translation had been dominated by submission, by fluent domestication. He strictly criticized the translators who in order to minimize the foreignness of the target text reduce the foreign cultural norms to target-language cultural values.
