Well Tamara,
the wolg and the coyote are not the same animal, and it's known name is : Coyote, and Prairie Wolf is just another way to put it's name. It is from the canine family, but the wolf differs from the coyote in many ways such as:
*The size, the wolf is bigger than the coyote
* the body structure, wolves have thick fur that covers the abdomen, coyotes have short fur
* the color and shape
* hunting Technics, coyotes are more Scavengers than Hunters
* Habitats, where they live, wolves usually live in cold areas,
hope i Helped you, Tamara!
Your faithfully,
Cutest Wittle Wolfy
