Ecology and Conservation of the Sirenia

2011
Dugongs and manatees, the only fully aquatic herbivorous mammals, live in the coastal waters, rivers and lakes of more than 80 subtropical and tropical countries. Symbols of fierce conservation battles, sirenian populations are threatened by multiple global problems. Providing comparative information on all four surviving species, this book synthesises

Regional Brain Morphometry and Lissencephaly in the Sirenia

Brain, Behavior and Evolution, 1990
Neuroanatomical structure was examined in the brains of West Indian manatees (Trichechus manatus) using computer-based morphometric methods. Although manatees have a small relative brain size, volume estimates of the major brain regions indicate that the telencephalon comprises 71% of total brain volume and is 90% cerebral cortex.

The modern Sirenia: their distribution and status

Biological Journal of the Linnean Society, 1973
The modern Sirenia have been little studied because of their present rarity and the difficulty of observing fully aquatic animals even though so large. These mammals are the only large aquatic herbivores. One of the three modern forms, Steller's seacow, is recently extinct; the dugong of the tropical Indo-Pacific region is now rare almost everywhere ...

Ecotoxicology of the Sirenia in the Twenty-First Century

2018
The four extant species of sirenians are unique among marine mammals because of their herbivorous diet, exclusively warm water distribution, and separate evolutionary lineage. Past ecotoxicologic studies focused largely on determining the concentrations of toxic elements and organohalogens in tissues of dugongs and West Indian manatees.
