A wolf's ears are also important. A wolf can hear high-pitch sounds that humans can't hear. A wolf hears from miles away by swiveling its ears until it finds the source of the sound. The way a wolf communicates is they use their tail, howl, scent, and ears. Wolves howl to gather their pack.
Wolves mark their territories by urinating on rocks and trees.
I've learned many fascinating things about the wolf's body. I've learned wolves can jump one story high. I've learned how it eats, and what it eats. Also I've learned how the wolf brings back food for it's pups, and more. I've also seen great pictures of wolves which I probably would never have seen.
