The Yellow-Spotted Doris is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the genus Chromodoris, family Chromodorididae, superfamily Doridoidea, order Nudibranchia, class Gastropoda, phylum Mollusca and kingdom Animalia.
Chromodoris luteorosea is a chromodorid nudibranch which grows to a maximum length of 55 mm. It is easy to identify by its colours. The body’s pale purple mantle is edged with a bright yellow line, with intense yellow or whitish points, circular or oval and irregularly distributed over the surface. These conspicuous points are surrounded by a white ring.
The rhinophores measure 6 mm in length and have 15 lamellae at the top. They are violet or reddish with a white pigmentation. The gills are in the back, surrounding the anus, and are formed by 9 leafy branches, of the same colour as the rhinophores.
