Hemolymph acid-base status of various crustaceans in freshwater (FW) and seawater (SW) under aerated conditions at temperature T. Postbranchial (a = 'arterial') hemolymph was drawn from the pericardial sinus, whereas prebranchial (v = 'venous') samples were taken from the infrabranchial sinus at the base of the walking leg. For each species, the typical mode of life (A = aquatic, T = terrestrial, X = amphibious) is indicated. ^#total CO₂, ^§this study, ^$unpublished data.
