Mule Deer Doe posing near Sundance Lodge Recreation Area south of Laurel, Montana. The mule deer (Odocoileus hemionus) is named for it’s large ears that resemble those of a mule. The species name hemionus is Greek and means “mule” while the Genus Odocoileus refers to the hollowed out chewing surfaces of the molars that add a mechanical advantage when chewing food. Odous is Greek for tooth and koilos is Greek meaning hollow. The differences between white-tailed and mule deer are the size of their ears (mule deer have larger ears), the color of their tails (mule deer tails have a black tip), and antler anatomy (mule deer antlers are bifurcated or forked while white-tail antlers branch from a main beam). Mule deer are typically larger than white-tails. Canon 7D, 400mm L lens, ISO 400, 1/1000 second @ f/8.
