The aeolid Cerberilla affinis is a nocturnally active sand-dwelling sea-slug. It is characterized by a black "mask" around the
rhinophores, and by whitish cerata with a thin black ring near the bases, followed by a white or yellow band, then a broad dark greyish subapical band and yellowish apices. The oral tentacles
are very long with alternating broad brown and whitish bands, and have a blueish tinge. The rhinophores are short, also with alternating brown and whitish bands and a blueish tinge.
The foot is wide and has angular extensions anteriorly.
