Robinson's Squirrel
''Sundasciurus robinsoni'', or Robinson's squirrel, is a species of rodent in the family Sciuridae. It is found in Indonesia, Malaysia and Thailand. The species ''Sundasciurus robinsoni'' has a Dorsum (anatomy), dorsum that ranges from medium brown with orange Agouti (coloration), agouti to dark brown (''S. r. vanakeni''), and its venter ranges from white to pale yellow/buff white, with a reduction in the extent of this pale coloration and a lack of distinct margins in the case of ''S. r. vanakeni''. Some populations (''S. r. balae'' and ''S. r. vanakeni'') have a grayish ventral coloration in limbs while others do not (''S. r. robinsoni''). It can be easily distinguished from other medium-sized western Sundaland ''Sundasciurus'' based on its ventral coloration and tail. All populations of ''Sundasciurus fraterculus, S. fraterculus'' except Siberut, ''Sundasciurus tahan, S. tahan'', and ''Sundasciurus altitudinis, S. altitudinis'' have a venter fur coloration homogeneously admixed ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/ricochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...
