The macrozoobenthos, usually defined as benthic macrofauna larger than 1 mm in size, is an essential element in benthic-pelagic coupling, because it mediates particulate and solute fluxes between the water column and sediments. It degrades organic matter that sinks to the bottom, changes biogeochemical properties of sediments via bioturbation and bioirrigation, affecting, for instance, rates of microbial oxidation and denitrification. It also serves as a food source for higher trophic levels, thus helping to sustain fish and fisheries. Macrozoobenthic communities, in turn, respond to organic matter supplied from the water column, hydrodynamic regime, and temperature. Major feeding groups (suspension and deposit feeders) differ in diet composition and vertical habitat distribution, which defines their functioning. In turn, their environment and changes in its characteristics affect these groups differently.
