Sleep in an Amazonian manatee,Trichechus inunguis

Experientia, 1992
For the first time, sleep was studied in a representative of the order of Sirenia. Slow wave sleep occupied 27%, and paradoxical sleep 1% of the total recording time in the Amazonian manatee. Trichechus inunguis. The circadian rhythmicity of sleep was pronounced.

Herpesvirus and adenovirus surveillance in threatened wild West Indian (Trichechus manatus) and Amazonian manatees (Trichechus inunguis), Brazil

Acta Tropica, 2023
African (Trichechus senegalenses), West Indian (T. manatus), WIM)], and the Amazonian manatees (T. inunguis, AMM). Whereas WIM inhabits both riverine and coastal systems in the western Atlantic, AMM is the only exclusively freshwater sirenian, endemic to the Amazon River Basin.

Temperature Regulation in the Amazonian Manatee Trichechus inunguis

Physiological Zoology, 1983
The mean core temperatures (Tc) of two Amazonian manatees (Trichechus inunguis) were 35.6 ± 0.1 C (X ± SD) and 36.1 ± 0.2 C at ambient water temperatures (Tw = 27–29 C). Based on metabolic rate (MR), the lower critical water temperature (TLC) of the larger manatee was 22-23 C. Above TLC, Tc varied with Tw, but the animal maintained Tc below TLC.

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.

Noninvasive Monitoring of Androgens in Male Amazonian Manatee (Trichechus inunguis): Biologic Validation

Journal of Zoo and Wildlife Medicine, 2009
The Amazonian manatee (Trichechus inunguis) is endemic in the Amazonian basin and is the only exclusively fresh water sirenian. Historically hunted on a large scale, this species is now considered endangered, and studies on the reproductive physiology are critical for the improvement of reproductive management of captive and wild populations of ...

Biology, conservation and status of the Amazonian Manatee Trichechus inunguis

Mammal Review, 1994
AbstractThe Amazonian Manatee Trichechus inunguis (Natterer, 1883) is the only exclusively freshwater sirenian and the smallest of the living species. Its inability to reduce peripheral heat loss limits its distribution to tropical waters. The species is endemic to the Amazonian region, being distributed throughout the Amazon basin, occurring mainly in
