A lynx is any of four medium-sized wild cats. All are members of the genus Lynx, but there is considerable confusion about the best way to classify felids at present, and some authorities classify them as part of the genus Felis. The Caracal, despite sometimes being called Persian Lynx or African Lynx, does not belong to this genus. Lynx have short tails and characteristic tufts of black hair on the tip of the ears. They have a ruff under the neck, which has black bars (not very visible), resembling a bow tie. They have large paws padded for walking on snow and long whiskers on the face. The body color varies from medium brown to gold-ish to beige-white; and occasionally, is marked with dark brown spots, especially on the limbs. All species of lynx also have white fur on their chests, bellies and on the insides of their legs which are extensions of the chest and belly fur. Also, the lynx's coloring, fur height and paw size varies by its climate range- in the Southwest US, the fur and color are short-haired, dark and the paws are smaller and less padded, as the lynx ranges to its colder Northern climes, the fur gets progressively thicker (for warmth), the color gets lighter (for camouflage) and its paws enlarge and become more padded for snowy environments.
