Eyeshine, like in thie Aye-aye (lemur), is produced when light is reflected off the tapetum lucidum, a special layer of tissue behind the retina that helps provide night vision for many nocturnal animals. Humans and other primates lack the tapetum lucidum. Photo: Tom Junek via Wikimedia Commons (CC 3.0)
