AMPHARETIDAE MALMGREN, 1866

Ampharetidae are tubicolous, as are most members of Terebelliformia, and share with Alvinellidae and Melinnidae the feature that their multiple grooved palps, usually called tentacles, can be retracted into the mouth. Typically, Ampharetidae are 10 to 60 mm long, though some adults are only a few millimetres long.
