Vulpes is a genus of the sub-family Caninae. The members of this genus are colloquially referred to as true foxes, meaning they form a proper clade. The word "fox" occurs in the common names of species. True foxes are distinguished from members of the genus Canis, such as domesticated dogs, wolves, jackals and coyotes, by their smaller size (5–11 kg), longer, bushier tail, and flatter skull. They have black, triangular markings between their eyes and nose, and the tip of their tail is often a different color from the rest of their pelt. The typical lifespan for this genus is between two and four years, but can reach up to a decade.
The range of the genus is very wide, present in a wide variety of habitats, from the desert to the Arctic, and from high altitudes in the mountains to open plains. True foxes are opportunistic and thrive in anywhere they can find food and shelter. They are also widespread in suburban and urban areas, where they can take advantage of human food supplies; however, they prefer to stay away from large industrial areas. In certain areas, foxes tend to do better where humans are present, including in many agricultural landscapes, forests and patchy woodlands.
