Limacia clavigera and possible egg mass

September 21, 2007
From: Joao Pedro Silva

Dear Bill,

Another one of yesterday's findings (I promise it's the last one!). Here are two photos of the same algal leaf, one of each side. I know one cannot be sure the eggs come from a particular species unless we see an individual laying them but this Limacia clavigera crawling so near makes a strong suspect. On the other hand, I've never seen L. clavigera spawning so I don't know what the egg mass looks like.

Locality: Peniche, 10 metres, Portugal, North Atlantic, 02 September 2007, Rocky bottom. Length: 15mm. Photographer: Joao Pedro Silva.

Cheers,
Joao Pedro

Dear Joao Pedro,

Thanks for your messages. They are always welcome. I am not sure if this is the egg ribbon of Limacia. One problem is that you give no indication of the size of the egg ribbon relative to the size of the slug. All I can say is the eggs are quite large, suggesting whatever slug produced them may have an abbreviated larval life, perhaps with the larvae hatching out as tiny crawling slugs rather than swimming veliger larvae..

Best wishes,
Bill Rudman
