DescriptionEubranchus farrani is very variable in colour. It usually has a translucent white body, with orange tipped rhinophores and oral tentacles. The white inflated cerrata have conspicuous sub-terminal orange or yellow rings. Some colour variants show individual exaggeration of certain markings. Others may have orange blotches ringed with blue. An all white form is common. Juveniles may have no colour other than pale brown or salmon pink. The cerrata are arranged in up to 10 diagonal rows of up to 5 cerrata in each half row. Oral tentacles and rhinophores are similar in size and relatively short. The maximum length for Eubranchus farrani is 2 cm.The spawn is a laid in a spiral ribbon of about 2 turns, flared out on its upper margin. Eubranchus farrani has in the past been confused with Eubranchus tricolour. However, Eubranchus farrani is more slender and smaller, with fewer cerata of less compressed shape, and different colour patterns (Thompson & Brown, 1984).
