You asked me to take note as regards how Chromodoris cf. geminus moves. Hopefully this photo provides visual illustration. I don't see that "the mantle edge is raised and lowered in one movement"... It just seems to "pleat" irregularly?! I have good video footage, but getting it to you is a problem.
Locality: South Coast KwaZulu-Natal, SOUTH AFRICA. Scottburgh - rocky reef - 24m., November 1999. Size: 75mm

It certainly looks like your animal is a different species. As I said earlier, C. geminus, has a very distinctive way of flapping the edge of the mantle so that the whole of the edge rises simultaneously then is lowered, then rises etc etc, in a spectacular rhythmic display. Your animal seems to be sending an irregular 'ripple' down each side of the mantle in a fairly normal chromodorid movement. I have moved this species to a separate page and for convenience will call it Chromodoris cf. geminus, the 'cf' being our shorthand for 'refer to'.
Thanks for the information,
Chromodoris cf. geminus from Mauritius
