Heart rates and gas exchange in the Amazonian manatee (Trichechus inunguis) in relation to diving.
Jour. Compar. Physiol. B: Biochem. Syst. Environ. Physiol. 156(3): 415-423. 3 tabs. 5 figs.
–Electrocardiograms and respiratory gas measurements of unrestrained captive animals showed a constant heart rate (here defined as the "normal" rate) during dives, slight respiratory tachycardia, and marked (probably fright-induced) bradycardia when the manatees were forced to prolong their dives. Because their metabolism is low, it can remain aerobic during most dives, and changes in alveolar gas composition are slower than in other marine mammals. Metabolic acidosis is apparently compensated for by metabolic rather than respiratory alkalosis.
