A large hall houses specimens of terrestrial mammals (skeletons and taxidermies) from all over the world: large elephants and hippos, lions, armadillos, anteaters… The concept of biogeography – the principle that the distribution of species on the planet follows geographical gradients and environmental factors – is explained by a video, while another introduces marsupials and monotremes. By playing a game, visitors can also discover evolutionary convergences between marsupials and placentals.
