Metabolism and Respiration of the Amazonian Manatee (Trichechus inunguis)

Physiological Zoology, 1980
A study was made of respiration and metabolism in Amazonian manatees (Trichechus inunguis) weighing between 20 and 170 kg. These animals had a low metabolic rate, 0.36 times that predicted by Kleiber's 1975 equation for placental mammals. They also had a low breathing frequency and minute ventilation, and high O₂ extraction and CO₂ output.

Heart rates and gas exchange in the Amazonian Manatee (Trichechus inunguis) in relation to diving

Journal of Comparative Physiology B, 1986
Unrestrained Amazonian manatees (Trichechus inunguis) maintained a constant heart rate during diving and exhibited a slight tachycardia during breathing. 'Forcing' the manatees to dive caused a marked bradycardia. They exhibited a more pronounced tachycardia during breathing after 'forced' dives and hyperventilated during recovery dives.
