Corambe pacifica from Carmel, California

Hi Bill,

Here is another cryptic kelp-dweller for you. I'm pretty certain these animals are Corambe pacifica. I found the egg ribbons first and the fact that they are quite different (being spirals rather than half-moons) from C. steinbergae is what alerted me to these slugs being a different species. As with C. steinbergae it took a bit to find them even after I'd found the eggs as they are nearly invisible on their byrozoan prey. Looking at the pictures you can see the posterior notch and the gill plume which I think make them C. pacifica though in my examples these features are more subtle than the picture in the Behrens and Hermosillo book.

Locality: Point Lobos, 15 meters, California, USA, Pacific, 13 October 2007, Macrocystis Kelp Blade. Length: 5-10 mm. Photographer: Clinton Bauder.

Hi Clinton,

Good show. Yes, they are almost invisible, from above. I love your oblique photo (right), as it shows the height of the specimens. This is exactly how I tell Branchers to look for these guys.

Thanks for sharing,
Dave Behrens
