The tapetum lucidum (Latin for 'bright tapestry, coverlet'; /təˈpiːtəmˈluːsɪdəm/tə-PEE-təm LOO-sih-dəm; pl.: tapeta lucida)[1] is a layer of tissue in the eye of many vertebrates and some other animals. Lying immediately behind the retina, it is a retroreflector. It reflects visible light back through the retina, increasing the light available to the photoreceptors (although slightly blurring the image). The tapetum lucidum contributes to the superior night vision of some animals. Many of these animals are nocturnal, especially carnivores, while others are deep sea animals.
Similar adaptations occur in some species of spiders.[2] Haplorhine primates, including humans, are diurnal and lack a tapetum lucidum.[Note 1]
