Recorded distribution in Britain and IrelandThis species can be found around the coasts of Britain and Ireland.
HabitatChaetozone setosa is common on muddy and gravel bottoms in the shallow sublittoral.
- Cylindrical body with 70-90 segments (chaetigers).
- Body length 20-25 mm.
- Head bears pointed, eyeless prostomium.
- Stout, pointed chaetae towards the end of the body; latter chaetae almost encircle the entire segment.
- Gills on at least 20 initial segments.
Additional informationThis species is a sedentary worm feeding on detritus using its long, wrinkled fragile palps. There are several species confused under this name in UK waters (Howson & Picton, 1997).
