First Non-Invasive Monitoring of Fecal Steroids in Greater Caribbean Manatees (Trichechus manatus manatus). [PDF]

Zoo Biol
This study established the first fecal hormonal reference values (P4/E2) for the Greater Caribbean manatee. Using non‐invasive ELISA, the authors found no significant differences between mature and immature females, highlighting that long‐term monitoring and ultrasounds are essential to fully understand their complex reproductive cycles.

Ultrasonographic Ocular Biometry of the Greater Caribbean Manatee (Trichechus manatus manatus). [PDF]

Vet Ophthalmol
ABSTRACT 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),
