Définition
Sens commun
Set of aquatic vertebrate animals which have the characteristic of being viviparous: the female lets the young grow in its belly, from which they get out alive. Marine mammals living in the oceans (cetaceans), as well as various freshwater species, such as the European otter, are aquatic mammals. Their mode of operation depends on the aquatic ecosystem where they live.
