The ability of crocodilian haemoglobins to bind HCO 3  - has been appreciated for more than half a century, but the functional implication of this is exceptional mechanism has not previously been assessed in vivo Therefore, the goal of the present study was to address the hypothesis that CO 2 primarily binds to Hb, rather than being accumulated in plasma as in other vertebrates, during diving in caimans. Here, we demonstrate that CO 2 primarily accumulates within the erythrocyte during diving and that most of the accumulated CO 2 is bound to haemoglobin. Furthermore, we show that this HCO 3  - -binding is tightly associated with the progressive blood deoxygenation during diving, therefore, crocodilians differ from the classic vertebrate pattern, where HCO 3  - accumulates in the plasma upon excretion from the erythrocytes by the Cl - -HCO 3  - -exchanger.
