Could F. ischitana eat C. peregrina eggs ?

June 13, 2007
From: Dominique Horst

On this occasion Flabellina ischitana seemed to be attracted to the Cratena peregrina eggs. Unfortunately I could not stay long enough to see what happened. Could F. ischitana eat C. peregrina eggs ? Is it something that is currently observed between aeolids species ?

Many thanks for your help

Dear Dom,
Species of Flabellina are thought to normally feed on hydroids. However if you look at any aeolids of the genus Favorinus on the Forum, you will see that they specialise on eating eggs of other opisthobranchs.

I would guess in this case the Flabellina was just climbing the hydroid in its daily search for food.

Best wishes,
Bill Rudman
