The kultarr (Antechinomys laniger) is a species of Dasyurid marsupial from Australia. They inhabit most of arid Australia in plains, deserts, and scattered forests, though a few populations have been found in salt marshes.
Kultarrs have large back feet that allow them to hop as an adaptation to the hot climates they live in so they can quickly move across hot sands. Their large ears are filled with blood vessels that allow blood to cool, thus cooling the bodies. They normally avoid the midday heat however and hide in burrows until night. Kultarrs are carnivores that feed upon small invertebrates.
