I thought you could add these to the predator list. The pycnogonid (sea spider) Anoplodactylus evansi which ate sea hares, sacoglossans and nudibranchs in aquaria, and labrid fishes or wrasses which ate adult Aplysia parvula and juvenile Aplysia dactylomela in subtidal field experiments near Sydney, Australia.

I've added them to the list and prepared a page on Anoplodactylus evansi as promised.
These observations are the result of studies Cary has been conducting over recent years on various aspects of the biology of Sea Hares around Sydney, especially defence and chemical ecology. This particular aspect of his work has been recently published in an interesting paper I have cited below.
