Placentation in the Amazonian manatee (Trichechus inunguis) [PDF]

Reproduction, Fertility and Development, 2008
Evidence from several sources supports a close phylogenetic relationship between elephants and sirenians. To explore whether this was reflected in similar placentation, we examined eight delivered placentae from the Amazonian manatee using light microscopy and immunohistochemistry.
