Dear Marc,

Apart from your photos being another good record of the nudibranch feeding on this white species of Dysidea, it is also gives us a look at another colour form of Hypselodoris fontandraui.

If I had seen just the large animal with its broad median whitish band, I would have suspected this was H. bilineata, but in the small animal alongside we can see that the median 'white' line shows signs of widening near the gills. It certainly makes me wonder if H. bilineata is just a colour form of H. fontandraui.

Best wishes,
Bill Rudman
