An extremely nice photo. Bali is an important locality because the suggestion that Chromodoris geminus is restricted to the Indian Ocean (in contrast to Chromodoris kuniei, which is restricted to the Pacific Ocean) is certainly shown to be incorrect.Locality:

Both Chromodoris geminus and Chromodoris kuniei have oval body form and wide mantle overlap. Both have purplish or brownish mantle with dark round spots with white haloes in the mantle.
The difference between the two is in Chromodoris kuniei the mantle edge is broad with purple colour followed by a narrow dark ring and an uneven yellow in the innermost band.
In Chromodoris geminus the mantle border consists of four different coloured rings – an outermost white, then faded purple, followed by another white and finally yellow.
