Bulla gouldiana aggregation, San Diego

May 25, 2006
From: Mike Neubig

Following on from my last message [#16670] I thought you might enjoy this group photo of eight Bulla gouldiana.  Also in the photo is a mucus tube derived from an individual that is off the left edge of the photo. This photo depicts a particularly dense cluster. More generally, in this region of the canyon rim, today, there would be 2 Bulla per field.

Locality: Valley-Sea-Toes, La Jolla Shores, 14m, California, USA, Eastern Pacific Ocean, 20 May 200, sandy sloping shoulder of La Jolla Canyon. Length: 20 mm typ (shell). Photographer: Mike Neubig.

Dear Mike,
It certainly looks like this is a good year from Bulla gouldiana in the San Diego region. In this photo it looks like the Bulla are grazing on a dark brown algal or bacterial layer covering the bottom. The pale grey areas, I presume, are areas they have scraped the layer off. From my experience, species of Bulla tend to feed on green algae or 'algal' layers like this.
Best wishes,
Bill Rudman
