Harrimaniidae Explained

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.^[1] In this family the development is direct without tornaria larva, and circular muscle fibers in their trunk is missing.^[2] There is some indication that Stereobalanus may be a separate basal acorn worm lineage, sister to all remaining acorn worms.^[3]
