Dear Bill,
It isn't possible to be a pale form of Dendrodoris denisoni with blue spots too.
Thanks for your comments and the forum.
Bests regards.

Dear Hugues,

Blue spots like those of C. miamirana are not exclusive to that species. found also in a number of species of sea hares, and as you have noted, Dendrodoris denisoni. Although you can't tell from photos, Ceratosoma miamirana has a stiff and solid mantle skirt, quite unlike the thin frilly mantle edge of Dendrodoris denisoni. One feature you can note from the photos is how the edge of the mantle seems to be cut out in a wavy or scalloped shape. If you look at other photos of this species, that is very characteristic of C. miamirana as well. However if you find a live animal, the best check is to turn it over and see the green reticulate pattern.

Best wishes,
Bill Rudman
