Trapezia Crabs Watercolors
These watercolor sketches of Trapezia crabs were drawn by Frederick Bayer, a former Smithsonian coral biologist, in 1947. Trapezia crabs live on and within corals, feeding on their tissue and mucus, and protect them from predators such as crown-of-thorns starfish. Bayer made these drawings in 1947, one year after the US military tested nuclear bombs on the coral reefs of Bikini Atoll in the Pacific. Read more about how the bombed reef has recovered.
