lynx...

A lynx  is any of the four species within the Lynx genus of medium-sized wildcats. The name "lynx" originated in Middle English via Latin from the Greek word "λύγξ" derived from the Indo-European root "*leuk-", meaning "light, brightness",[4] in reference to the luminescence of its reflective eyes.[4] There is considerable confusion about the best way to classify felids at present, and some authorities[who?] classify them as part of the genus Felis. Neither the caracal, sometimes called the Persian lynx or African lynx, nor the jungle cat, called the swamp lynx, is a member of the Lynx genus
