Ecology of Callinectes marginatus

Main Ref.	Fischer, W., G. Bianchi and W.B. Scott (eds.), 1981
Remarks	In shallow littoral environments, typically from intertidal pools to 3 m (Ref. 105199). Inhabits shallow salt water on sandy or sandy mud bottom (Ref. 435) in brackish waters of estuaries (Ref. 417). Also found on algae and grass flats, sandy beaches, rocky pools, eroded coral bases (Ref. 105199), coral reef (Ref. 121879), oyster bars (Ref. 105199), and edge of mangroves (Refs. 105199, 121880). Rarely found in the open sea, from the intertidal to depth of 25 m (Ref. 121880). Associated with the barnacle Chelonibia sp. (Ref. 105200). In general, portunids are opportunistic omnivores with preference for animal prey (Ref. 100840).
