Ecology Summary - Cephalopholis cruentata

Language:

Main Ref.	Randall, J.E., 1967
Remarks	Inhabit Thalassia beds and coral reefs. In the Gulf of Mexico, they are found on rocky reef ledge in depths greater than 27 m. Solitary (Ref. 26340) and secretive, they usually stay near hiding places during the day. Prefer to remain within a small area of the home range of about 2,120 square m especially during the day (Ref. 56524). Carnivore (Ref. 57616). Are nocturnal predators, adults feed mainly on fishes, with preference on Chromis multilineata, juveniles feed on shrimps. Due to its small size, this is not a particularly sought-after species. Easily approached and fed by divers (Ref. 9710).
