Temporal variations in aquatic consumption (open circles) and pleopod ventila- tory rates (solid circles) among specimens of Callianassa jamaicense when ambient oxygen tension (crosses on heavy line) is dropped to anoxia and then raised to hypoxia. Each value is mean rate for five animals. Vertical lines indicate ranges; rectangles indicate standard errors; horizontal lines indicate time span over which means are taken.
