Description
The fourline 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 four or occasionally six yellow projections. The gills and rhinophores are translucent white, tipped with yellow. In the South African animals the gills and rhinophores are black, and may be spotted with yellow. Alongside the gills is a pair of yellow-tipped projections. The animal may reach 20mm in total length. It is distinguished from the crowned nudibranch in having raised yellow spots on the mid-dorsal region.
