Did you know?
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. Many organisms adapted to deep-water pressure cannot survive in the upper parts of the water column: the pressure difference can be very significant (approximately … WebApr 14, 2024 · Thus, depth might be the most important driver of benthic community compositions overall [10,45], ... For sipunculans, the sample size was highest at latitude 45°, but most species were found at latitudes 15° and 5° meaning that the gamma species richness might be highest here, and that more sampling is needed (Figure 6B).

Regarding biodiversity, most benthic … WebBenthic environments that are shallow receive light and nutrients from the surface, which supports primary productivity and a diverse community of benthic organisms. As a result, these environments have a biomass that is moderate. The lowest biomass is found in deep benthic environments that are not under the influence of upwelling.
