Dear Francis & Pirjo,
Thanks for these photos of juveniles. They ceratinly have similalrities to H. infucata but I am pretty sure they are Hypselodoris kanga. One of the key differences is that in H. kanga the gills are triangular in cross section with a coloured line up the three corners, and a series of yellow spots on the ouside flat edge of each gill. Your photos show a nice series showing the development of this character. In the smallest animal [uppermost photo] the gills are not yet triangular in cross section but there is a coloured line up the upper and lower edges. In the middle photo the outer gills face has widened and has a coloured line along each edge. In the largest animal [lower photo] the spots are beginning to appear.
Best wishes
Bill Rudman
