Scandentia is an order of small mammals. Members of this order are called scandentians, or treeshrews. They are primarily found in Southeast Asia, with the Madras treeshrew instead in mainland India. They range in size from the Bornean smooth-tailed treeshrew, at 11 cm (4 in) plus a 9 cm (4 in) tail, to the striped treeshrew, at 23 cm (9 in) plus a 13 cm (5 in) tail. They generally live in forests, and primarily eat insects and fruit. No population estimates have been made for any scandentian species, though the Nicobar treeshrew is categorized as endangered.
