Ecology of Callinectes sapidus
Main Ref. Tavares, M., 2003
Remarks Benthopelagic (Ref. 97531). Hatching occurs in mouths of estuaries and shallow marine waters, development of larvae progresses in the ocean, followed by migration of megalopae and young crabs back into estuarine waters to mature into adults (Ref. 367). Found on soft bottoms (Ref. 106866). Burrows in muddy-sand bottoms (Ref. 108781). Juveniles occur on seagrasses. Highly cannibalistic; adult conspecifics are observed attacking tethered juveniles (Ref. 106866). Appears to be an opportunistic feeder (Ref. 108779).
