Description
Size: Max length 5.0 cm TL (male)

Color: Light orange along the dorsal and lateral surface. The regon between the rhinophores and the oral tentacles, the surface of the oral tentacles, the club of the rhinophores, the surface of the cerata and the integument of the pericardial orominence are deep orange in color. The middle one third of the oral tentacles and the cnidosacs of the cerata are coated with silvery shining granules. The foot is colorless. The hermaphrodite gland which is visible through the foot is light orange.

The bright red tips to the cerata of this aeolid apparently warn potential predators of the presence of the cnidosac which contains the stinging nematocysts removed from the cnidarian food of Moridilla brockii. When disturbed, it puts on a spectacular 'startle' display, uncoiling the large rolled cerata and pointing them at the source of the disturbance.
