Oxygen storage in beavers.
Ten wild beavers were anesthetized with pentobarbital and total lung capacity (60.5 +/- 4.8 ml/kg), hemoglobin (12.4 +/- 1.5 g/100 ml), blood volume (6.5 +/- 0.8% body mass), and myoglobin (1.2 +/- 0.3 g/100 mg) were determined. These measured values were used to calculate total oxygen storage capacity. Even though the beaver is a good diver (15-min submersion time), its oxygen stores are not large and are about one-third the stores of a good marine diver, the harbor seal.
