Color: Grey, brownish or bluish black

The body of Chaetozone setosa is strongly tapered at both ends and lacks parapodia. It is composed of 70-90 segments and few centimeters long. The pointed head bears no eyes. Filiform gills are present on a large number of segments throughout the first half of the body. The tail segments have a characteristic circle of chaetae.

The time of spawning varies greatly in different areas. Females with ripe eggs have been observed from May until autumn. Like all cirratulids, this species has non-pelagic larvae.

Chaetozone setosa leads a sedentary life within the sediment and also lives in empty burrows of other polychaetes.
