Remarks :

According Terry Gosliner : " This specimen sure looks like B. indopacifica and is very similar to the Madagascar specimen I collected with a yellow ring on the cerata"
    Synonymous : (according Worms)
               - No other name

Bibliographic data :

The body colour can range from a translucent light purple to deep reddish purple. A broad opaque white patch covers most of the head between the rhinophores and the anterior margin of the head. A smaller patch may be present just behind the rhinophores in some specimens. In all specimens observed an additional opaque white patch covers the pericardial region.
    The relatively short cerata are thick, widest in the middle and taper distally. They are almost entirely opaque white with some bluish purple pigment visible. The apex is translucent white.
    The cerata are densely clustered and continuous throughout the length of the body, without interruption in the pericardial region
    The bright red rhinophores share a common base, are perfoliate and have up to 28-32 lamellae each. The posterior portion of the rhinophores is covered by a fine dusting of opaque white pigment that extends to the apex. The anterior face lacks opaque white and is uniformly red.
    The tentacular anterior foot corners are short and are often held close to the body so they are not readily visible
    Nocturnally active nudibranch that has been found in protected to exposed rocky habitats from 1-17m
    This species was recently split from Babakina festiva (Gosliner & al., 2007). The specific name indopacifica was chosen by Gosliner, Gonzales-Duarte, & Cervera (2007) for its tropical Indo-Pacific distribution.
