Coyote and gray wolf share the same Kingdom (Animalia), Phylum (Chordata), Class (Mammalia), Order (Carnivora), Family (Canidae), Genus (Canis). Other pairs have different families or genera. For example, Coyote (Canidae) and American badger (Mustelidae) differ in family; European otter (Mustelidae) and leopard (Felidae) differ in family; American badger (Mustelidae) and leopard (Felidae) differ in family.
