A lynx is any of the four species (Canada lynx, Iberian lynx, Eurasian lynx, bobcat) within the medium-sized wild cat genus Lynx. The name lynx originated in Middle English via Latin from the Greek word λύγξ, derived from the Indo-European root leuk- ('light, brightness') in reference to the luminescence of its reflective eyes.
Lynx have a short tail, characteristic tufts of black hair on the tips of their ears, large, padded paws for walking on snow and long whiskers on the face. Under their neck they have a ruff which has black bars resembling a bow tie, although this is often not visible.
