Austraeolis ornata and eggs

Hi Bill,
I noticed you don't have any photos of the egg masses of Austraeolis ornata yet. I found this fairly large adult just finishing laying an egg
mass at Wollongong, NSW. When the adult was touched or disturbed, it ruffled and expanded its cerata as well as contorting/ spasming its body ... quite an impressive display for a little slug!

Thanks Rachel,
It's good to get the egg mass photo. Bob Rose (1985) reported the larvae to be planktotrophic. Your observation on it waving its cerata when disturbed, reminds me of Marina's recent message on defensive behaviour in Aeolidiella alderi.
Best wishes,
Bill Rudman
