In Flabelligera, a thick mucus sheath encases the body; the mucus is 

 formed by many gland cells in the epidermis and excreted through pores 

 over the surface of the body. A thick mucus sheath is present also in 

 species of Myxicola Koch, member of the family SABELLIDAE. 



Distribution: Poeobius meseres is known only from the northern 

 Pacific, from southeast Alaska to California, in about 350 meters.
