What a marvellous mimic for a nudibranch!
I'm pretty the characteristics of this animal match the Thorunna florens
group rather than T. australis. T. australis has just a single orange band on the rhinophores while T. florens has two. T. australis has only one white line per side, rather than the two of T. florens--the two on the left side of the animal are most visible in this photo. T. australis gills are more orange-red banded rather than red-tipped, which is typical of T. florens. T. australis also lacks the orange patch on the anterior margin so characteristic of all those we are currently calling Thorunna florens
and which is visible only as a red edge to the anterior margin in this frontal view. However, T. florens is so variable that I strongly suspect there are several different species currently being lumped under that name.
A juvenile individual.
An extremely nice photo of a typical individual. Note the orange streak mid-anteriorly on the mantle which is characteristic of Thorunna florens
This small chromodorid is characterised by the violet blue marginal to submarginal spots interrupted by an orange stripe at the front of the mantle, the two yellow or orange longitudinal stripes that loop around the rhinophores and gills, and by the orange rhinophores and gills.
This photo seems to show two individuals.
The distinctive feature is the golden bar that interrupts the purple marginal markings mid-anteriorly. All the other elements of the coloration are very variable intraspecifically, but this golden bar is consistent. Thorunna florens
is already known from Western Australia.
