The tubiculous polychaete Sabella sp. Myriochele oculata, Sabella sp. Polychaete worms are members of the segmented worm Phylum Annellida. Only a few large, free-living polychaete species have been regularly identified on the NMFS trawl surveys in the SE Bering Sea. The SE Bering Sea Sabellidae and Chaetopteridae range up to 15 cm in length and Maldanidae to 10 cm.
Most tubicolous polychaetes are either deposit feeders or filter feeders.
Tubicolous polychaetes are often found in dense mats. Red king crab dependance on such refuge substrate appears to decline from age 1 to age 4.
