Over the next 20 hr a gradual but sig- nificant (P < , 60%, SW; P < , 75%) SW) increase in weight occurred. Chitons exposed to 125% SW lost 8-9% of their original total-body weight and showed limited volume regulation after 12 hr exposure to the hyperosmotic 4 8 12 16 20 24 28 32 36 40 44 48 HOURS FIGURE 2.
