Description: An elongated, cylindrical body up to 55mm long with a small, spherical head surrounded by long tentacles. The first segments are directed forward and bear long hair-like bristles. The shape of the parapodial flaps depends on their location on the body. The colour ranges from red (anterior end) over dark green to black with white patches (posterior end). Digs U-shaped burrows.
Distribution: Poecilochaetus serpens was in both periods found across the Flemish, Zeeland and Hinder Banks as well as across the western coastal zone. However, the relative frequency of occurrence in both periods was low. Poecilochaetus serpens reached densities up to 300 ind./m2 (1994-2001 period).
Habitat: Poecilochaetus serpens is found in sediments with a median grain size between 150 and 550 ┬Ám. The species does not tend to have a clear preference and never reaches a relative occurrence exceeding 20%. Contrary to the median grain size, the mud content does play a decisive role in the habitat preference: Poecilochaetus serpens prefers sediments with low mud contents (maximum 30%).
