Ancestral chromosomal signatures of Paenungulata (Afroteria) reveal the karyotype of Amazonian manatee (Trichechus inunguis, Sirenia: Trichechidae) as the oldest among American manatees [PDF]
BMC Genomics, 2023 Background Chromosomal painting in manatees has clarified questions about the rapid evolution of sirenians within the Paenungulata clade. Further cytogenetic studies in Afrotherian species may provide information about their evolutionary dynamics ...

Ultrasonographic Ocular Biometry of the Greater Caribbean Manatee (Trichechus manatus manatus). [PDF]
Vet OphthalmolABSTRACT This study aimed to characterize the ocular biometry of the Trichechus manatus manatus applying B‐mode ultrasonography across different age groups. Twenty‐two animals were assessed employing a portable ultrasound device equipped with a linear transducer. Five ocular parameters were assessed: corneal thickness (CT), anterior chamber depth (ACD),
