That was pretty fun, so I decided to try another from a little further away to show the extent of this "field of bubbles." [I was kneeling next to the tidepool, holding an underwater camera below the surface, so I couldn't quite see what was in the frame.]
Wow! It worked pretty well...and there was a bonus! A nice Surfgrass Limpet (Lottia paleacea) was in the center of the photo near the top. This limpet is remarkably well adapted for life on a surfgrass blade. [For an introduction to the limpet, see the post from 7 June 2012.]
I kept taking pictures from different positions, and I ended up with one more image of the surfgrass blades, the bubbles, and the limpet:
I'll definitely keep trying to capture this beautiful underwater scene in other surfgrass meadows!
