Ecology of Metacarcinus magister

Main Ref.	Shirley, S.M., T.C. Shirley and S.D. Rice, 1987
Remarks	Epibenthic in estuaries and nearshore environments (Ref. 104211). It is found on soft bottoms in very low intertidal areas to a depth of 360 meters (Ref. 865). Found on seagrasses (Refs. 104216, 106869). Juveniles inhabit and forage on estuaries, particularly in oyster reefs, oyster beds (Ref. 104211, 113901), and eelgrass (Ref. 104211).
