The dark blue, teal, and gold tapetum lucidum from the eye of a cow Retina of a mongrel dog with strong tapetal reflex. The tapetum lucidum (Latin for 'bright tapestry, coverlet'; / t ə ˈ p iː t əm ˈ l uː s ɪ d əm / 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.

The eye of a bird is larger compared to the size of the animal than for any other group of animals, although much of it is concealed in its skull. The ostrich has the largest eye of any land vertebrate, with an axial length of 50 mm (2.0 in), twice that of the human eye. [1] Bird eye size is broadly related to body mass.
Choroid dissected from a calf's eye, showing black RPE and iridescent blue tapetum lucidum. The RPE was known in the 18th and 19th centuries as the pigmentum nigrum, referring to the observation that the RPE is dark (black in many animals, brown in humans); and as the tapetum nigrum, referring to the observation that in animals with a tapetum lucidum, in the region of the tapetum lucidum the ...
Line art or line drawing is any image that consists of distinct straight lines or curved lines placed against a background (usually plain). Two-dimensional or three-dimensional objects are often represented through shade (darkness) or hue . Line art can use lines of different colors, although line art is usually monochromatic.
Tapetum (Latin for carpet or tapestry) can refer to: Tapetum (botany), tissue within the sporangium (especially the anther), which provides nutrition for growing spores . The innermost wall of microsporangium; Tapetum lucidum, a reflective tissue layer associated with the retina of some vertebrates
Many prey and predator animals have naturally retroreflective eyes by having a reflective layer called the Tapetum lucidum behind the retina, since this doubles the light that their retina receives. Double-ended cat's eye is Shaw's original design and marks road centre-line
The eyes of slow lorises are forward-facing, which gives stereo vision. Their eyes are large [41] [84] and possess a reflective layer, called the tapetum lucidum, that improves low-light vision. It is possible that this layer blurs the images they see, as the reflected light may interfere with the incoming light. [85]
