Ecology of Sipunculus nudus

Main Ref.	Göthel, H., 1992
Remarks	Inhabits shallow, subtidal sand flat. Depth: shallowest is 12 m (Ref. 358); littoral zone to 2275 m (Ref. 775, 1819); continental shelf, continental slope (Ref. 1456); intertidal zone, sandy bottoms, rock crack, eulittoral zone; mud, sand (Ref. 1784). Intertidal to 30 m, and few from 100-900 m (Ref. 1840). Burrows (Ref. 116123). A sub-surface deposit feeder (Ref. 96376). Builds a permanent burrow in the sand, obtaining food particles by moving the finer organic materials washed into the burrow (Ref. 125338).
