Remarks :

Identification confirmed by Nathalie Yonow.
    Synonymous : (according Worms)
               - No other name

Bibliographic data :

Some specimens have extra black spots on the mantle.
   Like other Chelidonura, C. pallida feed on tiny acoel flatworms, which live on almost every coral reef substrate. Chelidonura "smell" or sense their flatworm prey with a pair of round, bristle covered lobes on either side of the head. These sensory lobes are used also to find potential mates and when tailing other individuals, a common behavior for members of this genus.
    Similar in colour to Chelidonura electra , but that species has no black markings, and the left "tail" is much fleshier.
