Peltodoris nobilis mating

December 4, 2006
From: Jim Lyle


Dear Dr. Rudman,

Southern California is currently undergoing a population boom of Peltodoris nobilis (formerly Anisidoris nobilis ). This large, yellow nudibranch seems to be everywhere along with its bright yellow egg ribbons.

On a dive this past weekend, with camera in hand, I encountered two, different-colored individuals copulating, and another laying its eggs; attached are photographs for the forum.

Locality: Palos Verdes Peninsula, 25 metres, California, USA, Pacific Ocean, 25 November 2006, Rock reef. Length: 60 mm. Photographer: Jim Lyle.

Best,
Jim

Thanks Jim,
I included a close-up to show the delicate folding of the egg string within the egg ribbon.

Best wishes,
Bill Rudman
