Paralvinella palmiformis, collected from hydrothermal vent on Endeavor Ridge, is about 3.5 cm long. It's a species of bristle-footed Annelids or fan-head worms in the family Alvinellidae. They usually build mucus tubes and feed with flattened, ciliated tentacles, plus obtain nutrition from episymbiotic bacteria living on their surface. Typically live with caudal end coiled around other worm tubes or attached to the surface of sulfide chimneys. They are a deposit feeder and cover themselves with mucus. Paralvinellids also are symbiotic with ectosymbiotic bacteria which live on the mucus.

From the Latin palmiformis, palm-shaped, an allusion to the shape of the gills which earned this species the nickname "palm worm" by early observers.
