Aldisa sanguinea from California

Hi Bill,

Found this Aldisa sanguinea on a funny looking red sponge that I don't recall seeing before. Certainly the spots on the back of the slug make sense in this context.

I'm not sure if the eggs belong to the Aldisa but they do look like the egg mass in message #15161.

Locality: Partington Canyon, 10 meters, CA, USA, Pacific, 21 July 2007, Rocky Reef. Length: 20 mm. Photographer: Clinton Bauder.

Hi Clinton,

What a perfect example of this species. Bill's close-ups show the texture of the mantle well. Note the notal tubercles are smooth, not caryophyllidic.

As far as the eggs are concerned, they certainly look like those of Aldisa. The sponge I can't help you with.

Thanks for sharing,
Dave Behrens
