Comparative Respiratory Physiology in Cetaceans
In the current study, we used breath-by-breath respirometry to evaluate respiratory physiology under voluntary control in a male beluga calf [Delphinapterus leucas, body mass range (M(b)): 151–175 kg], an adult female (estimated M(b) = 500–550 kg) and a juvenile male (M(b) = 279 kg) false killer wha...
