Temperature Regulation in the Amazonian Manatee Trichechus inunguis
Physiological Zoology, 1983The 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, 1980A 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.

Acute necrotizing colitis with pneumatosis intestinalis in an Amazonian manatee calf
Diseases of Aquatic Organisms, 2016On 25 January 2014, a 1 mo old female Amazonian manatee Trichechus inunguis calf weighing 12 kg was rescued by air transport in Guajará, Brazil, and transferred to Mamirauá Institute's Community-based Amazonian Manatee Rehabilitation Center. The calf presented piercing/cutting lesions on the back, neck, and head, in addition to dehydration and ...

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, 1994AbstractThe 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

Acoustic tagging for counting feeding events of captive Amazonian manatees
The Journal of the Acoustical Society of America, 2012The Amazonian manatee is one of four extant species in the mammalian order Sirenia. They are restricted to the freshwater rivers, lakes and floodplains of the Amazonian river basin where they eat floating and emergent aquatic plants. Visual observation of wild manatees is nearly impossible because of the turbid water and tiny exposure of nose at gentle
