Harrimaniidae
Harrimaniidae is a basal family of acorn worms. A taxonomic revision was undertaken in 2010, and a number of new genera and species found in the Eastern Pacific were described. There is some indication that Stereobalanus may be a separate basal acorn worm lineage, sister to all remaining acorn worms.Species
