Abstract: 1. Stomach contents were examined in 65 specimens of Cyanoplax hartwegii taken from three different intertidal microhabitats near Monterey, California. 2. In the Pelvetia bed habitat, Pelvetia made up 80% of the total diet, while in the higher crevice habitat, the algae Hildenbrandia, Endocladia, Petrocelis, and Cladophora spp. comprised 90% of the diet and were eaten in relatively equal amounts. 3. In the high tidepool habitat, C. hartwegii ate a much wider variety of algae. Gigartina and Hildenbradia together made up 40% of the diet. Crustose corallines and Gigartina occured in all habitats examined, but were eaten by Cyanoplax only in the tidepools.
