						Characterized by its pattern of bright orange lines on a white or yellowish background. One line runs along each edge of the mantle, from the head, to just behind the gills where it folds under on each side to run forward midway between the mantle edge and the edge of the foot, which is bordered in orange. Gills are edged with range, so is the rhinophore.

				Life cycle and mating behavior				
					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					Members of the order Nudibranchia are simultaneous hermaphrodites.  Mating behavior:  Both individuals darts their penis toward each other to induce one to act as a male and the other as the female.  The victorious one to penetrate the body wall is the dominant male.  Life cycle:  Eggs are deposited on a substratum where they develop and hatch into (planktonic) vestigial veliger larval stage and further grow as adults.
