The Red Fox (Vulpes vulpes) can be found throughout the Northern Hemisphere. They are the largest of the "true foxes", measuring up to 20" tall and weighing up to 30 lbs. They are easily recognizable by their long tail which is longer than half their body length and red rust coloring.  They use their tail for balance, warmth, and to signal other foxes. Although hunted for sport in some areas, they are not considered endangered.
