Well, no bones except in the clownfish. Sometimes I wish I had been a marine biologist studying invertebrates. These photos remind me of the old aquarium in La Jolla, California, right next door to the Salk Institute. That little Art Deco building housed a circular array of only a dozen or so medium-sized tanks, and those tanks were filled with anemones of many colors. The effect was breathtaking. These iPhone photographs were taken at the Denver Zoo’s Tropical Discovery building.
