About
The southern flying squirrel is a pocket-sized gliding rodent that weighs only a couple of ounces.
This species is noticeably smaller than its close relative, the northern flying squirrel. Adult males and females are very similar in size, with neither sex growing significantly larger than the other. Its flat, furry tail accounts for nearly half of its total body length. This low body weight helps the squirrel glide easily between tree trunks without dropping quickly to the ground.
