This species can reach more than 40 mm in length. The body is white and slightly translucent, with the back tinted reddish or light pink, slightly darker between the first groups of cerata and with bluish tones in some areas. There are two long orange spots on the head. The oral palps are slightly bluish at the base and opaque and tinted orange in the tip. The rhinophores are smooth and translucent at the base and rounded with short orange warts near the tip, the apex itself is white. The cerata are grouped in 8-10 groups on each side of the body, arranged more or less evenly over the dorsum. The cerata are colored blue with an orange apical end, they are long, narrow and hold the brown digestive gland but it is masked by the blue coloration of the cerata skin. The foot is wide and coloured soft pink and the anterior zone holds and a pair of fine triangular propodials palps.
This species can be found under stones or in shallow infralittoral rocky walls with plenty of hydrarians and other invertebrates. It has been reported that it feeds on anemones Aiptasia mutabilis and Sagartia sp. The spawn consists of a white, translucent spirally wound ribbon of about 25mm in diameter with eggs 125 microns of diameter.
