Ecology of Callinectes ornatus

Main Ref.	Tavares, M., 2003
Remarks	Occurs from the intertidal zone to 75 m (Ref. 106798). Inhabits sandy or muddy bottoms, or shell and sponge covered bottoms (young crabs). Tolerates a broad range of salinities from 0 to 50 ppm and temperatures of 18 to 31°C. May be seen in bays or river mouths or even in freshwaters, but is abundant in waters of relatively high salinities. Feeds on mollusks, other bottom invertebrates, fishes, carrion and detritus. Albinistic individuals occur where substrates are light colored (Ref. 367).
