This very fat individual has probably just finished its meal.

An undescribed species. By comparison Gymnodoris alba does not have the enormous propodial tentacles.

Comment from Richard Willan on photo #2952
An undescribed species. This is an exceptional photo showing the long, thin penis everted from the genital pore at the level of the gills.

Comment from Richard Willan on photo #2638
An undescribed species. More than simply “hitching a ride” on this scorpionfish, it is feeding on the dorsal fins.

Comment from Richard Willan on photo #2274
An undescribed species. A pair of mating individuals. This is an astounding photo! Gymnodorids are often highly cannibalistic, so in this species the genital apertures have moved to a position level with the gills – a most unusual rearward position that is unique in nudibranchs – presumably to move the site away from the mouth to prevent one partner eating the other during mating. The only other species with the reproductive organs in this rearward position and row of papillae on the oral margin is Gymnodoris bicolor, but that dos not have the greatly enlarged propodial tentacles. In this species it seems that not only the penis is protruded, but also the vagina of the other partner, which makes it even more unique.

More detailed images showing the head, gills and site of the reproductive aperture are needed to enable a more exact identification of this species.
