Re: Aphelodoris gigas? from Western Australia

Concerning message #19599:

Dear Bill and Bruce,
I would say its unlikely that this animal is Aphelodoris gigas. One of the features of A. gigas is that it has a white line in the centre of the rhinophores (anteriorly and posteriorly), and this appears to be lacking on this animal. There are also many other undescribed Aphelodoris species in this region. However, aphelodorids are characterized by variation in colouration, and definitely need more work!
kind regards
Nerida

Thanks Nerida,
I hope the tentative nature of my identification was obvious. I am a bit frightened by your suggestion of  'many other undescribed Aphelodoris species' in the region. The existing ones in southern Australia are already quite a struggle to separate from each other - the addition of another group along the Western Australian coast might be too much for me.

In the case of Bruce's animal, hopefully he may have a photo which shows the rhinophores more clearly

Best wishes,
Bill Rudman
