Dendronotus diversicolor eggs

I believe these are Dendronotis diversicolor, and not D. albus seeing the position of the white stripe on the back. I am not satisfied with the quality of these photos but offer them as they may provide some help for others in identifying the eggs of Dendronotus diversicolor. It was stunning to find huge numbers of this species on sea fir (Abietinaria) at this depth. These 3 images were taken within a 1 square foot area. May 21, 2007 - they are still at it in the same location.

Locality: North East Pearse, 78 feet, British Columbia, Canada, Pacific Ocean, 28 April 2007, mud bottom. Length: 3 cm. Photographer: Jackie Hildering.

Hi Jackie,

The validity of Dendronotus diversicolor has been in question for some time and is currently being studied by a student of Dr. Angel Valdes. As suggested elsewhere on the Forum [message #16223 ], let's not use the name D. diversicolor, until matters are resolved. Again, I believe your photo contains the eggs of two differnt species. The tight mass (not sure what species laid it) in the middle left photo is quite different from the loose ones in your photo that I believe are those of the D. albus.

Hope this helps,
Dave Behrens
