| Biology: |
The larvae of this species may remain planktonic for up to 4 months before settlement depending on water temperature (Ref. 2763). Found along the continental shelf edge and slope. Associated with smooth or dimpled, unconsolidated and consolidated silt-clay sediments. Also occurs in canyon community (Ref. 96189). Displays deep-to-shallow migration as crabs mature wherein adult females generally inhabit shallower water than adult males, while juveniles tend to occur in deeper waters than adults (Ref. 96186). Reported to be opportunistic feeders. Adults eat benthic fauna such as sponges, hydroids, gastropods, scaphopods, small polychaetes and crustaceans, as well as larger prey like demersal and mid-water fish, squid and quill worm. Also scavenges deadfalls of fish and squid. May at times resort to deposit feeding and consume man-made artifacts (Ref. 96189). |
