Comment from Richard Willan on photo #4405
22 February 2011: This species is included in the definitive list of Victorian nudibranchs by Robert Burn under the name of Chromodoris reticulata. Therefore that is the opinion of an expert. The truth is that until somebody studies this red-reticulate group of Chromodoris species anatomically and genetically we cannot come to a firm conclusion. So leave it as Chromodoris reticulata.

A very interesting animal from a temperate locality that Chromodoris reticulata would not be expected.

Note the two cream-coloured commensal shrimps side by side in front of the gil

A very small juvenile individual

Comment from Richard Willan on photo #8101
This is an atypical individual in two aspects – the peculiar right rhinophore is an aberration (resulting from a developmental mutation), and there is no gold marginal band (intraspecific variation).

Comment from Richard Willan on photo #8051
In this photo the right rhinophore is not visible – either it is withdrawn down into the rhinophoral pocket, or it has been lost. Another atypical feature of this individual is the lack of a gold marginal band.

A nice photo of a typical individual. Note the numerous gills (more than 14 at least), which characterise this species.

Comment from Richard Willan on photo #7929
This individual has only 12 gills – the absolute minimum number for Chromodoris reticulata.

Comment from Richard Willan on photo #5912
This individual has many gills (more than 14), but not all of them are fully extended so it seems there are only few.

A typical individual.

Comment from Richard Willan on photo #4604
This individual has the right colours on the mantle border for Chromodoris reticulata and probably more than 12 gills (but this is impossible to see), so it is more probably Chromodoris reticulata than Chromodoris tinctoria.

Chromodoris reticulata or possibly an undescribed species.

Comment from Richard Willan on photo #3718
Difficult to be positive about the identity of this individual because its gills are withdrawn so we can’t count them.

Comment from Richard Willan on photo #3630
I use that name even though there is no golden marginal band because there are multiple gills (more than 14). I think the number of gills is more important than the exact colour pattern on the mantle.

A typical individual.

Comment from Richard Willan on photo #1400
This is Chromodoris reticulata and not Chromodoris tinctoria. This individual has (or seems to have in the case of unclear photos) more than 14 gills and no rows of blood-red spots on the outer flanks of the mantle that are possessed by the real Chromodoris tinctoria.

Comment from Richard Willan on photo #305
This specimen is hard to name as Chromodoris reticulata with certainty because it has no golden band on the mantle margin and white speckles. However there are definitely a large number of gills, which point to it being closest to that species.
