Ecology of Dardanus arrosor

Main Ref.	Markham, J.C., 2003
Remarks	Bathyal. Inhabits continental shelf and slope (Ref. 2782). It is eurybathic, on coastal detritic bottoms to bathyal muds (Ref. 105665). Uses shells of Bittium latreilli (Ref. 105639). Opportunistic scavenger and predator. Feeds on live crabs, dead shells and fishes (Ref. 106108). Other isotope data (δ15N=9.66±0.25, Ref. 106518).
