Bill,

Dave Behrens asked me to share this photo of mating Pleurobranchaea californica. The photo was taken off San Diego, California in 265 m depth from a ROV with a Scorpio Digital (Nikon CoolPix 955) camera.

Regards.

Thanks John,

Dave Behrens in Eastern Pacific Nudibranchs notes that species has been reported from 1200 ft so your animals are certainly at the deeper part of its known range. It is interesting how in each animal the gill is held aside to facilitate mating. The reproductive organs, and openings, are on the right side just beneath the anterior part of the gill.

Best wishes,
Bill Rudman
