Dirona albolineata mating and spawning

September 10, 2007
From: Marcos Perreau Guimaraes


Hi Bill,
Diving Arena Rock, California, near the rock and at a depth of about 60', I came into a groups of dozens of Dirona albolineata, a few mating or spawning eggs. All the mating pairs I saw had one white and one brown color variation. Here a few pictures.

Locality: Arena Rock, N of Point Arena, 20 m, [60 ft], California, USA, Pacific NW, 02 September 2007, Offshore pinnacle. Length: most about 50 mm. Photographer: Marcos Perreau Guimaraes.

Cheers,
Marcos.

Hi Marcos,

Beautiful photos. It is great to get the eggs with the animal so we know their ID. Concerning the mixed mating of different colored individuals, this is likely to be just a coincidence.

Thanks for sharing,
Dave Behrens
