What Preys on Sea Hares?
March 7, 2000
From: Claire
I have been researching sea hares for a web page I am creating. Your site has been extremely the helpful in this process. Thanks. One area I have had a hard time researching is the predators of sea hares. Any insight into this area?

Dear Claire,
If you can get hold of a copy of Johnson & Willow's review of Defense in Sea Hares which I noted last year, there is a section on predators. One difficulty is knowing which animals are serious, regular predators, and which have eaten a Sea Hare as a once-off 'experiment' or as the result of a chance meeting. In their paper they suggest sort out a few predators which have Sea Hares as a majot part of their diet. They include a large green sea anemone Anthopleura xanthogrammica, the aglajid navanax inermis, the bailer shell Melo amphora and the giant starfish Coscinasterias calamaria. But you should have a look at the paper for details about which species are eaten etc.
You should also be aware that the eggs are also a useful food item as are metamorphosing larvae about to settle out of the plankton.
Let us know when you complete your website Claire, I would like to have a look.
Best wishes,
Bill Rudman.
