This species has been observed on Madagascar Island

Order : Nudibranchia
Suborder : Dexiarchia
Superfamily : Aeolidioidea
Family : Facelinidae
Distribution : Indian Ocean
Maximal size : 40 mm
Abundance :

Species characteristics :

Head and body a milky translucent orange colour

The lower three quarters of each cerata is translucent, with dense white speckling, which obscures the digestive gland duct. The upper quarter of each cerata is quite colourful, with a milky orange and white tip, and then below that a bright purple region, and below that a dull greenish brown section.

The purple and greenish brown regions are sections of the digestive gland duct visible through the transparent ceratal wall, while the orange tip is due to pigmentation on the ceratal wall.

Bibliographic data :

Head and body a milky translucent orange colour, with body darkening behind the second ceratal arch to a deeper orange where the gonads show through.
   The oral tentacles are long and tapering and about one and a half times the length of the rhinophores. (not in our specimen...) The basal half of each oral tentacle is transparent with the distal half being milky orange.
   The basal third of the rhinophores is transparent, while the upper two thirds is a milky orange. The rhinophores have scattered, rounded bumps all over them.
   The foot is translucent with a faint orange tinge, the anterior end producing long, tapering foot corners. A median band of orange runs to the tip of the tail from between the most posterior cerata
   The cerata are arranged into six pairs of multi-rowed arches each raised on a pad, and there is also a group of irregularly arranged cerata at the posterior end of the body. As in other species of the genus, the cerata are long and slender, and are held out from the body in large clumps
   Sakuraeolis kirembosa feeds on Eudendrium hydroids
