Diversidoris flava (Eliot, 1904) [Chromodoris]

Click the thumbnail photos to enhance!

Diversidoris flava is characterized by a bright yellow colour, including the gills and the rhinophores, and a bright red or orange-red line at the edge of the mantle. This line widens at fairly regular intervals to give a pattern of spaced semi-circular spots around the mantle edge. The mantle is ovate with a semi-permanent fold about mid-way along each side giving the animal the appearance of having a thin 'waist'. Pretty similar are
Diversidoris crocea which has a whitish submarginal band and
Noumea laboutei which has red gills and rhinophores.
