The treeshrews (or tree shrews or banxrings) are small mammals native to the tropical forests of Southeast Asia. They make up the families Tupaiidae, the treeshrews, and Ptilocercidae, the pen-tailed treeshrews, and the entire order Scandentia. There are 20 species in 5 genera. Treeshrews have a higher brain to body mass ratio than any other mammals, including humans, though high ratios are not uncommon for animals weighing less than a kilogram.
