A photo of a specimen of the terrestrial slug Polytoxon robustum, taken on the campus of the University of Eastern Africa, Kenya.
Land snails on agave plant. These terrestrial gastropods cope with hot and dry conditions during the day by entering a dormant state called "aestivation." A membrane of dried mucus provides attachment and insulation, and the light color of the shell helps to reflect sunlight. Photo taken by Dr. Oluwole Oyedeji, near Casablanca, Morocco.
