Scolecida is an infraclass of polychaete worms. Scolecids are mostly unselective deposit feeders on marine detritus.
==Characteristics== Scolecids have parapodia with rami that are all alike. The prostomium is distinct. The head has no appendages or palps and is usually conical, though in the Scalibregmatidae, it has a T-shaped tip, and in Paraonidae, there is a single, central antenna. In some families there are sometimes some tiny eyespots. The oesophagus is evertable forming a sac-like proboscis which may have several finger-like lobes. The anterior segments and their appendages are all similar. The notopodia and neuropodia consist of unbranched capillary chaetae, sometimes with hooks. There is a single central gill in Cossuridae on an anterior segment and simple segmental gills are present in some other families.
