The Antillean manatee produces broadband vocalizations with ultrasonic frequencies.
Journal of the Acoustical Society of America 147(2): EL80-EL86. 1 tab. 3 figs. doi.org/10.1121/10.0000602 Feb. 5, 2020.
–ABSTRACT: Antillean manatees produce vocalizations reported to be important for communication, but their vocal behavior throughout their geographic range is poorly understood. A SoundTrap recorder (sample rates: 288/576?kHz) was deployed in Belize to record vocalizations of wild manatees in a seagrass channel and of a young rehabilitated and released manatee in a shallow lagoon. Spectral analysis revealed broadband vocalizations with frequencies up to 150?kHz and a high proportion of calls with ultrasonic components. Ultrasonic frequency components appear prevalent in their vocal repertoire and may be important to manatee communication.
