Anembryonic Gestation in Wild South American Sea Lion, Otaria flavescens.
We present the first record and description of an anembryonic gestation in a wild South America sea lion, Otaria flavescens (Carnivora, Pinniped). This is the first report of an anembryonic gestation in a wild marine mammal species. This description furthers the knowledge of general aspects of the reproduction of an otariid species, which presents the particularities of delayed implantation and polygynic breeding system, and adds information on a reproductive abnormality in marine mammals.
