The Lowly Salt Marsh/Mud Snail
Cerithidea californica, California Salt Marsh or Mud Snail, San Diego, California. This snail is common on muddy tidal flats and intertiday zones. They feed largely on algae and detritus. It is under pressure in some areas from introduced habitat competitors such as Ilyanassa obsoleta in the San Francisco Bay area. I had seen it around for some time in various locales around the county and snapped this photo to look it up with.
