Ecology of Crangon crangon

Main Ref.	Fischer, W., G. Bianchi and W.B. Scott (eds.), 1981
Remarks	Found in both marine and oligohaline waters (Ref. 95752). Also inhabits brackish lagoons (Ref. 2779). Found on fine sand or slightly muddy sand (Ref. 434); also over coarse sand (Ref. 96391). Juveniles are epifaunal on seagrass and bare sand flats (Ref. 106879). Mobile (Refs. 95752, 96470). Free-living (Ref. 3123). Able to occupy areas with high exposure and low salinity (Ref. 95730). Carnivorous (Refs. 95752, 96470). Feeds on small benthic organisms (small crustaceans, annelids and mollusks) and fishery discards (Ref. 434).
