Eggs? of Limacea cockerelli

March 22, 2006
From: Kevin Lee

Attached is a photo of a Limacia cockerelli. When veiwing it on my computer monitor, I noticed what seems to be a circular mass of "eggs", in the upper left-hand corner of the image. Do you know if these are eggs of the L. cockerelli?

Locality: Shaw's Cove, Laguna Beach, 20 feet, California, Eastern Pacific, 11 June 2005. Length: 0.5 inch. Photographer: Kevin Lee.

And might the SeaSlug Forum have a compendium of Opisthobranch eggs on file?
Tnx, K:-)

Dear Kevin,

The identification of lone egg masses can be quite problematic.  Unless you obseverve an adult laying the ribbon, or the species is extremely common and there are lots of adults and ribbons scatterred around, you can't really give an intelligent ID.

To be honest with you I am not sure I have ever accurately documented the egg mass of Limacea cockerelli.  I am sure Jeff Goddard has, and hopefully he will lend a hand here.

Concerning a compendium of egg masses on the Forum - no there is not a 'single' compendium, but you can always use Bill's SEARCH on "eggs."

Best wishes,
Dave Behrens
