Aeolid Nudibranch

Tenellia sp


Small Nudibranch around 2 cm with black Rhinophores, its cerrata are bluish in colour with segments of gold/yellow.


Found this in a colony of hydroids, which was probably their food source.


This Aeolid Nudibranch has been mis-identified many times as Cuthona yamasui, with the genus also wrongly placed, and now updated to the genus Tenellia. Tenellia was a small genus until a DNA phylogeny of the former family Tergipedidae resulted in most species of Cuthona being transferred to this genus. This picture is of a yet to be described Tenellia species.
