The most extreme disguise assumed by the Arthropod parapodium or appendage is that of becoming a mere stalk supporting an eye - a fact which did not obtain general credence until the experiments of Herbst in 1895, who found, on cutting off the eye-stalk of Palaemon, that a jointed antenna-like appendage was regenerated in its place.
