Définition : Living in the fluid medium (water or air) but unable to maintain their position or distribution independently of the movement of the water/air mass (adapted from Lincoln et al., 1998).
Définition : aquatic organisms that construct and inhabit simple unbranched vertical shafts with only one opening to the surface. These are primarily above-sediment filter-feeders, surface deposit-feeders, and subsurface deposit-feeders (head-down, conveyor-belt feeders)

Définition : Upward conveyors are vertically oriented species that typically feed head-down at depth in the sediment. Vertically oriented head-down feeders actively select and ingest particles at the deeper sediments and egest these non-locally as faeces in the sediment surface

Définition : The marine benthic biome (benthic meaning 'bottom') encompasses the seafloor and includes such areas as shores, littoral or intertidal areas, marine coral reefs, and the deep seabed.
Définition : sediment that accumulates in the flat or very gently sloping areas of the deep ocean basin floor. The three main types are siliceous oozes, calcareous oozes, and red clays.

Définition : consumers specializing in labile organic matter, which is easily metabolized; usually low molecular weight compounds, eg: simple sugars or proteins. For instance, metabolic scaling puts intense selective pressure on small organisms to ingest foods rich in labile organic matter; the residence time in a very short gut is too brief for enzymatic hydrolysis, so they specialize in rapidly metabolizable compounds.
