Re: Flabellina verrucosa feeding on scyphistomae

From: Bill Rudman

I just got a message from Bernard Picton who suggested the scyphistoma in Chad's photo is probably Aurelia aurita so I had another search of McDonald & Nybakken's list and found the following references to feeding on Aurelia aurita 'polyps'. Clearly predation by F. verrucosa on the scyphistomae stage of Aurelai can be an important factor in Aurelia populations, at least in Sweden.

• Hernroth, Lars, & Fredrik Gröndahl. 1985. The biology of Aurelia aurita (L.) 3. Predation by Coryphella verrucosa (Gastropoda, Opisthobranchia), a major factor regulating the development of Aurelia populations in the Gullmar Fjord, western Sweden. Ophelia, 24(1): 37-45.
• Hernroth, L., & F. Gröndahl. 1985a. On the biology of Aurelia aurita (L.): 2. Major factors regulating the occurrence of ephyrae and young medusae in the Gullmar Fjord, western Sweden. Bulletin of Marine Science, 37(2): 567-576.

Cheers,
