Congenital Ocular Findings in an Antillean Manatee (Trichechus manatus manatus). [PDF]
Vet Med SciThis study reports the first documented case of bilateral congenital cataract associated with retinal dysplasia in an Antillean manatee (Trichechus manatus manatus) calf. Ophthalmologic examination and ocular ultrasonography confirmed lens opacity at the posterior pole, which correlated with behavioural deficits consistent with visual impairment.

Evolution of canonical circadian clock genes underlies unique sleep strategies of marine mammals for secondary aquatic adaptation. [PDF]
PLoS GeneticsTo satisfy the needs of sleeping underwater, marine mammals, including cetaceans, sirenians, and pinnipeds, have evolved an unusual form of sleep, known as unihemispheric slow-wave sleep (USWS), in which one brain hemisphere is asleep while the other is ...

Comparative Cognition & Behavior Reviews, 2022 Vocal production learning is the ability to modify a vocal output in response to auditory experience. It is essential for human speech production and language acquisition. Vocal learning evolved independently several times in vertebrates, indicating evolutionary pressure in favor of this trait. This enables cross-species comparative analysis to be used

Life Expectancy in Marine Mammals Is Unrelated to Telomere Length but Is Associated With Body Size
Frontiers in Genetics, 2021 Marine mammals vary greatly in size and lifespan across species. This study determined whether measures of adult body weight, length and relative telomere length were related to lifespan.
