Bibliographic data :

Collingwood first described this species from the South China Sea. Because of its small size and lack of gills he considered it to be most probably a juvenile of a species of Gymnodoris ( Trevelyana ). He found specimens in tide pools and described it as `very active and flexible, assuming at different times the most singular of forms, resembling in turn a fox, a rabbit, a cat, according to its different attitudes.' Although no internal anatomy was described, the size, colour, lack of gills, simple rhinophores and rapid movement and flexibility, clearly characterise this species which has been found, under various names in many parts of the Indo-West Pacific
    It have a direct development
    It feeds on the polychaete Spirorbis sp which builds small white calcareous tubes
