what is the function of the tapetum lucidum in animals?
superior night vision
tapetum lucidum









































the tapetum lucidum (latin: "bright tapestry; coverlet", plural tapeta lucida) is a layer of tissue in the eye of many vertebrates. 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. most primates, including humans, lack a "tapetum lucidum", and compensate for this using perceptive recognition methods.









































section::::function and mechanism.









































presence of a "tapetum lucidum" enables animals to see in dimmer light than would otherwise be possible. the "tapetum lucidum", which is iridescent, reflects light roughly on the interference principles of thin-film optics, as seen in other iridescent tissues. however, the "tapetum lucidum" cells are leucophores, not iridophores.
