Surf Grass

Phyllospadix torreyi


During minus tides the surfgrass is left dry for a short time, but is a wonderful visual cue to where sea level is located. As a photosynthetic plant it creates oxygen as a waste product of photosynthesis. Normally this is washed away by the ocean currents, but at a minus tide, surfgrass in still tidepools on sunny days is covered with bubbles of pure oxygen.

Thanks Cindy for looking into the two grasses.
@Leuba -- the grass will stay lush because it's almost always just under the water line!

Thanks so much CoralAvery for the ID. That CA Tidepools site is useful for anenomes too!
