The family Rhodopidae are one of the few molluscan groups for which we have no clear idea of their phylogenetic relationships. Have a look at the Rhodopemorpha Fact Sheet for further background information.
This species differs from free-living flatworms by its relatively slow movements. It shares the colour pattern of white body and orange markings with some other species of Rhodope but thearrangement of the orange, with an ornage band around the body, behind the head, and a medio-dorsal longitudinal band in the posterior half of the body are considered unique to this species. It grows to about 1.5 mm long. Like R. veranii it lives in shallow subtidal regions with Ulva or other green algae.
