Chelidonura inornata from nthn New South Wales

Hi Bill,
Here is another slug that I collected at
Angourie Pool on our recent collecting trip to northern New South Wales, Australia [March 2002].

I suspect that it is probably a species of Chelidonura.

Thanks John,
Yes this is Chelidonura inornata. Your photo shows the ventral surface - it is probably crawling upside down along the surface film. It shows the characteristic orange-yellow patches on either side of the mouth. It is easy with digital images to remove blemishes but I haven't removed the yellow stain at the bottom left of your photo as I suspect it has been secreted by the animal. Just as Sea Hares, such as your Bursatella, secrete a red or purple secretion when disturbed, all aglajids have a yellow secretion.
Best wishes,
Bill Rudman
