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, 2008Neuroanatomical 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 totalbrain volume and is 90% cerebral cortex.
