Concerning message #16504:

Hi again, Bill,

Keeping your request in mind (#16504), I revisited La Jolla Shores (California) in search of Gould's Bubbles  [Bulla gouldiana ]. On my second attempt, my trusty buddy, Jackie, led us right to a stampeding "herd". In the widest angle shot, there are at least 20 snails, visible. Five critters in a 10 inch frame. Thus, extrapolating, I estimate, in the area, the snails numbered in the thousands. Photos are attached.

Locality: La Jolla Shores, approx 25 feet, San Diego, California, USA, Eastern Pacific, 21 May 2006, sandy bottom, with patches of green algae. Length: average 2 inches. Photographer: Kevin Lee.

PS: The dive day ended on a high note as I attended David Behren's nudibranch presentation at the Birch Aquarium. Very interesting & humorous. He sure knows his nuds!

Dear Kevin,
By coincidence I am just posting messages from Mike Neubig [#16673] which illustrate what I guess is part of widespread aggregation in the San Diego area. I see the dark brown layer is covering the bottom in your photos too. Thanks very much for the photos. Species of Bulla certainly seem to be either in boom or bust populations
Best wishes,
Bill Rudman
