Long-tongued arboreal mouse
The long-tongued arboreal mouse, ''Rhagomys longilingua'', is a South American rodent species of the family Cricetidae. It is found in a variety of habitats, including dense forest, in Bolivia and Peru at elevations from on the eastern side of the Andes.〔 The species is at least partly arboreal. It is distinguished from the Brazilian arboreal mouse (''Rhagomys rufescens''), the only other known member of ''Rhagomys'', by spiny fur and certain skull features such as the presence of beading in the interorbital region.〔
==Description==
The adult long-tongued arboreal mouse weighs in the range and has a tail that is nearly as long as the head-and-body length. The fur is short and dense, and consists of a mixture of long slender hairs and spines, giving the mouse a bristly appearance. The upper parts are olive-brown and the underparts are buffish-ochre with fewer spines. The tail is dark above and slightly paler below, with rings of scales, and hairs increasing in length towards the tip and ending with a tuft of hairs. The fore feet have five long digits with broad, blunt tips and short, narrow claws that hardly project beyond the tips of the digits. The hind feet are short and broad and have five digits with blunt, calloused tips, the hallux (big toe) being shorter than the others and having a nail rather than a claw. The female has three pairs of mammary glands.
