context: Cloven-hoofed animals have been very successful mammals. They now include 240 different living species [1], and different species have adapted to cold as well as scorchingly hot areas. Although the species are large in size, more and more species have been found, for example, in Southeast Asia. Many species are at risk of extinction due to poaching and loss of habitat due to deforestation or other causes. Hippos are the only ungulates that are at least partially adapted to aquatic life. The heaviest species is the African hippopotamus, weighing about 4.5 tonnes, while the lightest and smallest ungulates are dwarf deer (about 1 kg, height at withers 35 cm). The longest neck is the giraffe.
