Comment from Richard Willan on photo #14219
An atypical individual because the single red band on the rhinophores is exceptionally broad.

Comment from Richard Willan on photo #8931
A very small juvenile individual

Comment from Richard Willan on photo #7753
This species apparently shows very great intraspecific variation

Comment from Richard Willan on photo #4652
The colouration on the rhinophores (red with a white apex) distinguishes this species from Hypselodoris maculosa.

Comment from Richard Willan on photo #4618
In contrast, Hypselodoris maculosa would have two red rings around the rhinophores.

Comment from Richard Willan on photo #2494
See my comments about this species in the preceding set of photos today.

Comment from Richard Willan on photo #775
Not a typical individual (see explanation in the photo from Lembeh). This could well be an undescribed species.

Comment from Richard Willan on photo #583
A typical individual. See how different this individual is to the one from Ambon and this one from Bali, that’s why I suggested this is really a group of species not just one.

Comment from Richard Willan on photo #198
This may be a complex of several different species.
