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.

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

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.

Difficult to be positive about the identity of this individual because its gills are withdrawn so we can’t count them.

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.

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.

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.
