Most artiodactyls live entirely on land and reside in a range of terrestrial habitats, such as savannah, forest, mountains, desert, and farmland. One artiodactyl family, Hippopotamidae, is semi-aquatic and can be found in freshwater lakes, ponds, streams, and rivers. Cetaceans, on the other hand, are exclusively aquatic and inhabit the world's oceans, as well as some freshwater rivers and streams.
