Concerning message #21460:

I notice that David and Leanne have sent several messages about Nembrotha roseannulata and they have all shown the same colour variation. In reviewing some of my old photos I came across this one showing an interesting pairing of two different colour forms.

Dear Bruce,

Thanks for checking through your photos. This is a good example of how we learn new things all the time. I don't recall seeing this white-ringed colour form before so capturng mating with the pink-ringed animal is pretty convincing evidence they are the same species. In the close-up alongside I see traces of the pink colouration in a couple of places.

Best wishes,
Bill Rudman
