Malocclusion in an Arctic Wolf (Canis lupus arctos) from northeast Greenland
I document the first case of malocclusion in an Arctic Wolf (Canis lupus arctos) from Greenland. All canine teeth of a wolf found dead on the tundra of northeast Greenland showed evidence of heavy anterior wear resulting from occlusion with the opposite teeth. Additional heavy wear on the incisors i...
