Physical Adaptations

Grey Wolves have great stamina. They can run for a long time without getting tired. They also have special hair to keep out moisture. On rainy or snowy days, this lets them go longer. On their paws, they have claws and pads for traction. This helps when it's rainy, snowy, icy or wet. In a chase, these wolves can run up to 40 miles per hour. That's almost 2 times faster than the speed limit in our neighborhoods. This helps because they don't want to lose their prey in a chase. Grey Wolves also have keen hearing and smelling. Their sense of smell is almost 100 times keener than ours. Because of this, they are able to locate and track prey better.

Behavioral Adaptations

Each wolf has a distinct howl. They use this for identification. Another form of communication is barks, yelps, whines and growls, like a dog. This is used for communication. Wolves are nocturnal. They move at night and cover great distances.
