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, during a survey of marine fauna on the coral reefs of Bikini Atoll in the Pacific, one year after the US military tested nuclear bombs there.
