Chromodoris coi

First time I found one of these creatures I was shooting wide angle on "The Mount" near Redang, Malaysia, and I had only just changed from macro to wide angle for that dive, Murphy's Law.

The photograph below is cropped from a shot using a 10.5mm fish-eye lens

The only other example I found was this small juvenile off Bonita Island on the west side of Maricaban Island in the Philippines.

Photos will be added shortly
