Diaphorodoris luteocincta (M Sars, 1870)


Description: This animal may grow to up to 11mm in length. Unlike the species in the genus Onchidoris, D. luteocincta has a conspicuous coloration. The mantle is white with a central red blotch. The mantle tubercles are white and conical in shape. There is a yellow band around the mantle edge.

Habitat: Probably feeds on bryozoans such as Crisia and is often found on silt covered rocks.

Distribution: Found all around the British Isles and reported from Norway to the Mediterranean. Several other species occur in the Mediterranean and the true D. luteocincta may not occur there. The variety alba, which occurs in the Mediterranean and north to the south coast of Britain, is almost certainly a distinct species. It lacks the red pigment in the centre of the back.

Similar Species: The colour of this nudibranch distinguishes it from any other in the British Isles.
