Main Ref. Holthuis, L.B., 1991
Remarks Found in the continental shelf and slope (Ref. 94799). Epibenthic (Ref. 87524). Sedentary (Ref. 94799). Inhabits muddy bottoms in which it digs its burrows. Nocturnal and feeds on detritus, crustaceans and worms (Ref. 4). An active predator or scavenger (Ref. 94757). Another isotope data (δ15N=6.26±0.14, n=3, Ref. 106518).

Associated with Hematodinium sp
Association remarks
Parasitism inside host (The parasitic dinoflagellate Hematodinium sp. lives in the hemolymph (blood), causing a condition called bitter crab disease (BCD) (Ref. 119370).)


Feeding type mainly animals (troph. 2.8 and up)
