botnlífi
Botnlífi refers to life forms that inhabit the bottom of aquatic ecosystems, including the seabed, riverbed, or lakebed. It encompasses organisms that live on the surface of sediments (epifauna) as well as those that dwell within sediments (infauna) and the smaller organisms living in the spaces between sediment grains (meiofauna).
Botnlífi occurs in marine, freshwater, and brackish environments, from shallow coastal zones to deep-sea basins. Distribution
Major groups include infauna such as polychaete worms, bivalves, and crustaceans; epifauna such as barnacles, sea
Ecological roles of botnlífi include bioturbation or sediment mixing, nutrient cycling, and habitat structure. Many species
Threats to botnlífi include pollution, sedimentation and turbidity, hypoxia, dredging, coastal development, and climate-related changes in
