In a fresh water environment, a plurality of animals mainly use the bottom of a water body as a place for activities such as inhabitation, foraging, reproduction and the like. The systemic location, morphology, individual size and their life cycle on the water bottom of these animals vary widely, but their common ecological characteristics are the main habitat for the water bottom, and these animals are collectively called benthonic animals. Benthonic animals have a long life span and limited migratory capacity, and include sensitive and resistant species, and are therefore often referred to as "underwater sentinels" that can monitor chronic emissions of organic pollutants for long periods of time. The community structure, species composition and diversity of the benthonic animals, the uniformity of the community and other parameter changes are closely related to the conditions of the sediment and the water quality. Therefore, the benthonic animals are often used as indicator organisms for environmental monitoring and widely used for evaluating the conditions of bottom sediment, water body environment and water quality.
