The profundal is often defined, in accordance with Thienemann (1925), as the deepest, vegetation-free, and muddy zone of the lacustrine benthal. This zone is located beyond the range of sunlight penetration. Light intensity, oxygen concentration, and (during summer and autumn) temperature are markedly lower than in the surface layer. [1], The lack of light and oxygen in the profundal zone determines the type of biological community that can live in this region, which is distinctly different from the community in the overlying waters. Hence, this zone is also known as the aphotic zone. Add an answer. In Lake Baikal, however, phytobenthos occurs at depths down to 50 m.

Characteristics of a lentic aquatic system: This causes the . With increasing productivity, the littoral zone may loose its heterogeneity that results in a single pro-fundal biomass maximum of the zoobenthos. A Dictionary of Biology Creatures in this zone are adapted to living without light It can be found below the thermocline and epilimnion.
