Ecology of Nephrops norvegicus

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).
