    Action: changed name from "Haliotis sp." to "Haliotis walallensis "

    Reviewer's comments:
         "It's hard to tell from just the photo, but I think this is the "flat abalone." It appears to have 5 open pores. Reds only have 3 or 4 open pores.

    Flat abalone (H. walallensis) have a mottled yellowish and brown epipodium, with a pebbly appearing surface and lacy edge. The tentacles are greenish and slender. The shell is flattened, narrow, and marked with low ribs. There are 5 to 6 open pores, and the pore edges are moderately elevated above the shell surface. Flat abalone range from British Columbia, Canada to San Diego, California. They are found in the subtidal zone from 20 feet down to at least 70 feet. Flat abalone reach 7 inches in length, but are commonly under 5 inches. Empty shells are very common in Monterey and Carmel bays.
