Ecology of Polybius henslowii

Main Ref.	Gaspar, M.B., M.D. Dias, A. Campos, C.C. Monteiro, M.N. Santos, A. Chicharo and L. Chicharo, 2001
Remarks	Benthic species with pelagic phases (Ref. 4225). Benthopelagic (Ref. 105043). This is a swimmer, carnivorous species (Ref. 96498). Enters coastal waters in loose shoals close to the sea surface (Ref. 4225). Opportunistic carnivore. Reported to exhibit cannibalism. Has a mixed diet of pelagic, benthic infauna and epibenthic animals (Ref. 105043).
