Experientia, 1992•SpringerFor 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. During
the sleep period, the manatee woke up for a short time for each respiratory act.

Abstract
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. During the sleep period, the manatee woke up for a short time for each respiratory act. Interhemispheric asynchrony of the electrocortical slow wave activity was found.
