Short Description:

The twin-crowned nudibranch is a smooth-bodied variably coloured nudibranch. The ground colour is white or grey and there are usually black, yellow or orange stripes longitudinally along the notum, though these can be absent. The head has six yellow projections. The gills and rhinophores are black, and may be spotted with yellow. There are raised yellow spots on the mid-dorsal region. Alongside the gills are two or three pairs of yellow projections, which differentiate the animal from the crowned nudibranch and the fourline nudibranch.
