Defensive colouration in sea slugs

Species of Jorunna are superficially very similar to Rostanga but they differ in reproductive and radular morphology. This purple 'species' is always associated with a similarly coloured sponge. However there are also other 'species' with colours matching their food sponges so it is possible there is only one variable species which changes colour to match its food sponge.
