Harbor porpoises are active divers that exchange O(2) and CO(2) with the environment during a fast single breath upon surfacing. We investigated blood O(2)-transporting properties, buffer characteristics, Cl(-) transport via the erythrocyte anion exchanger (AE1), circulating nitric oxide metabolites and hemoglobin nitrite reduction in harbor porpoises with the aim to evaluate traits that are ad...
