The gray wolf originally ranged throughout Missouri, but with settlement the species was gradually exterminated. While there is no evidence of a breeding population in the state, wolves are listed as a protected species in Missouri, and they occasionally wander into Missouri from northern states.
About Mammals in Missouri
More than 70 species of wild mammals live in Missouri: opossums; shrews and moles; bats; rabbits; woodchuck, squirrels, beaver, mice, voles, and other rodents; coyote, foxes, bear, raccoon, weasels, otter, mink, skunks, bobcat, and other carnivores; deer and elk; and more. Most of us recognize mammals easily — they have fur, are warm-blooded, nurse their young, and breathe air.
