Examination of published molluscan morphological data matrices20,21,49 reveals obvious symplesiomorphies shared between these taxa (e.g., external univalved shell), but we find no clear morphological synapomorphies for the gastropod-scaphopod clade. They are found in the South Atlantic Ocean, Gulf of Aden, and several places in the eastern Pacific Ocean. This alternative topology was, however, rejected by the Approximately Unbiased (AU) test (p=0.001). Phylogenomic studies have also supported a clade including Gastropoda, Bivalvia, and Scaphopoda, although there has been inconsistency in recovered relationships among these taxa19,20,28,30. Anat.

They measure 0.25 to 1.25 inches (3 to 30 millimeters) in length. Special symbiosis with bacteria might contribute to this remarkable eurybathy that is unique amongst extant monoplacophoran species.
