Oxygen consumption (VOZ) was measured as hermit crabs (Coenobita compressus) walked at controlled velocities on a motor-driven treadmill inside a small respirometer. The crabs displayed an aerobic response to exercise with a rapid increase in VQ2 reaching a steady state in about 5-6 min followed by a rapid recovery. The highest VQ2 was four times the resting rate. V^ was directly dependent on t...
