What eats sea slugs?
One big gap in our knowledge is what actually eats Sea Slugs. Except in rare cases such information, where it exists, is published not in the malacological literature, where we would look, but in the literature associated with predator, for example fish biology journals, often in stomach contents lists which don't appear as keywords or any easily searchable form. I think this is a good time to add a page for predation records where we can gradually accumulate such information on who/what eats sea slugs. So here is the page. It's basically empty at present, so any records/observations, either personal observations or from the literature, would be appreciated.
All observations in the list below are linked to a message containing details.
