Wolves have several key adaptations to help them survive: they have strong hind limbs, feet with five specialized toes and sturdy teeth to facilitate survival in harsh conditions. Wolves have key physical characteristics to help catch and consume prey. They may also last up to two weeks without feeding, during which time their metabolisms slow to a crawl.
Wolves are built much like sports cars: they have lean, lightweight frames and slender builds, which makes them fast and aerodynamic. These predators can run at great speeds, thanks to their powerful hind legs and muscular system, and cover great distances on foot. Wolves are classified as digitigrades, which means that only their toes touch the ground when they walk. This essentially turns their feet into small springs, which makes them even faster. Wolves’ front paws have five toes, which are specially adapted for tearing through hides and thick skins of grazing mammals, which are their primary sources of food. Wolves have massive canine teeth to puncture and cut through flesh and pick meat off bones, and they have molars capable of crushing through animal bones. Lastly, wolves have large and simple stomachs that are suited for storing food rather than facilitating rapid digestion. Wolves may eat 20 pounds of food at once then go for two weeks before feeding again.
