Benthos are highly sensitive to contamination, so their close proximity to high pollutant concentrations make these organisms ideal for studying water contamination. [21] Benthos can be used as bioindicators of water pollution through ecological population assessments or through analyzing biomarkers. In ecological population assessments, a ...
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.
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.

Saharan Spanish (Spanish: español saharaui) is the variety of the Spanish language spoken in Western Sahara and adjacent regions. This variety is heavily influenced by both Spanish cultural links and a strong expatriate community who live in Spain and Hispanic America , particularly Cuba .
Pelagic zones. The ocean can be conceptualized as being divided into various zones, depending on depth, and presence or absence of sunlight.Nearly all life forms in the ocean depend on the photosynthetic activities of phytoplankton and other marine plants to convert carbon dioxide into organic carbon, which is the basic building block of organic matter.
How language affects identity and mental health. Though the lack of Spanish fluency is common among second- and third-generation Latinos, it can often result in teasing by family and friends.The ...
The benthic boundary layer (BBL) is the layer of water directly above the sediment at the bottom of a body of water (river, lake, or sea, etc.). [1] Through specific sedimentation processes, certain organisms are able to live in this deep layer of water.
Russian paleontologist Ivan Yefremov [Efremov] called the genus Benthosaurus "deep water lizard" (from Ancient Greek βένθος (benthos) "depth, deep water") in his original 1929 description, "in view of its clearly indicated adaptation to life in deep water" shown by "the position of the orbits and the flatness of the skull."
