Main Ref.	Robinson, L.A., S.P.R. Greenstreet, H. Reiss, R. Callaway, J. Ccraeymeersch, I. de Boois, S. Degraer, S. Ehrich, H.M. Fraser, A. Goffin, I. Kröncke, L. Lindal Jorgenson, M.R. Robertson and J. Lancaster, 2010
Remarks	Common in shallow waters from the intertidal to 80 m (Ref. 83653), common at depths not deeper than 40 m (Ref. 435). Found mostly in rocky shores, confined to the lower tidal mark (Refs. 101396). Inhabits on sand or mud (Ref. 435). Carnivore; trophic level 2.6 (Ref. 96418), trophic level 2.98 (Ref. 435). An opportunistic feeder, mostly preys on molluscs and crustaceans and also feeds on detrital material and large quantities of brown algae (Ref. 96482).
