Sea Hares - attack & defence

April 17, 1998
From: P.M. Johnson

I'm currently writing a review article with my PhD advisor (Dr. Dennis Willows, director of the Friday Harbor Marine Lab) on defence in sea hares. If anyone as observed any sea hares being attacked by a predator under natural conditions I would love to include the details of the account in the review.

Thank you for your help.

The only example I know of is Richard Willan's unpublished report of a large multi-armed starfish Coscinasterias eating an Aplysia dactylomela in New Zealand. If Kirsten Benkendorff's report of the starfish Patiriella exigua possibly eating the egg mass of Dolabrifera dolabrifera is confirmed, that could possibly count as another example. A common feeder on Aplysia egg strings is the aeolid nudibranch Favorinus japonicus. Have a look at my list of references on chemical defence and related topics.
