Heavier body segments have relatively lighter skin covering than smaller segments; larger, heavier animals have relatively less surface area than smaller ones. (This latter phenomenon is not apparent in the similarly sized animals used here.) This is based on the fact that whereas weight (both of segment and of body) increases by the cube, surface area increases by the square (Thompson, 1969). Muscle varies more, has a greater effect on total weight and physiology, and is more sensitive to loco- motor differences than skin and bone. Muscle consti- tutes over 40 percent TBW in the kangaroo, over 50 percent in the agouti, cavy, and jackrabbit. By contrast with these terrestrial forms, muscle ranges 232 T. I. Grand
