When I did a dissection of a cow's eye in Biology, we came across this term. The tapetum lucidum, which is not found in the human eye, functions to reflect light onto the retina. It especailly helps with night vision since it can reflect light even at very low intensities. It is shiny, glittering with a bluish colour.A specialized surface reflects the light within the eye and is found in the eyes of animals that live under conditions of low-intensity light. Not found in humans.

Is tapetum lucidum present in humans eye?
I learned this today while dissecting a cow's eye in my lab class. Human's don't have the tapetum lucidum layer. This is present in animal eyes. It's what causes them to glow in the dark. There sometimes is a rare occurrence when it does happen in humans, which causes them to lose their sight. I don't remember the name of the disease that my professor said it is though.
What is the function of the choroid coat?
The tapetum lucidum (reflective material) reflects light back into the retina. This allows the animal to see at night. (Although this allows for better night vision than that of humans, it distorts the clarity because the light is reflected so much.) The tapetum lucidum is also responsible for the "glowing" eyes of animals, such as cats, when a small amount of light reflects off the tapetum lucidum in an otherwise dark room.
The layer of cells many nocturnal animals have behind the retina?
Tapetum Lucidum , at least i give the answer..
What is the iridescent portion of the choroid layer found in nocturnal animals?
The tapetum lucium. The tapetum is a reflective structure that lies beneath the retina. It acts like a mirror; reflecting light back through the retina so the retina gets more opportunities to capture light. Animals that are active at night have a tapetum. Dogs, Cats, Horses, and Cows all have tapetums. It causes the yellow or green glow you see when light hits an animal's eyes.
In thin skin what is absent?
Stratum lucidum
What is the function of the tapetum lucidum in a cow?
The tapdeum lucidum is a reflective membrane in the cow's eye that allows it to see better in low light (such as at dawn or dusk).
Which part of a cat's eye reflects light?
the tapetum lucidum is what reflects the light
What is the reflective layer in the lining of the eye called?
The reflective layer in the lining of the eye is called the tapetum lucidum.
What does a cats tapetum lucidum help it do?
See better in the dark
How do animals eyes glow in the dark?
Animals eyes do not glow, their eyes only reflect light. This reflection of light, which appears to make the animal's eye glow, is called eyeshine and it is caused by the tapetum lucidum, which is a layer of tissue in the eyes of many vertebrate animals. The tapetum lucidum allows the animal to see better in low-light situations (such as after dark) by reflecting the light back into the retina. When a photo is taken of an animal that has tapetum lucidum in it's eyes, the light reflected from the flash of the photo often makes the eyes appear to glow. The same thing occurs when light is flashed into the eyes of animals that contain tapetum lucidum after dark.

What do eye eyes do at night?
Bears eyes dont glow because they dont have the tapetum lucidum that make there eys glow. A large number of animals have the tapetum lucidum, including deer, dogs, cats, cattle, horses and ferrets. Humans don't, and neither do some other primates. Squirrels, kangaroos and pigs don't have the tapeta, either.

Tapetum lucidum
What is the raccoon's eye color in the dark?
The tapetum lucidum is a layer of tissue in the eye of many vertebrates. It is located immediately behind the retina and it reflects visible light back through the retina, increasing the light available. In raccoons the eye shine is yellow.
Why do animals eyes shine in the dark?
Some animal's eyes shine in the dark because of the presence of the tapetum lucidum* in the choroid layer (the middle layer) of the eye. This layer helps to reflect light, presumably allowing them to see better in the dark. This is why most animals which could be considered nocturnal have noticeably shinier eyes than, for example, humans, who do not have any evidence of the tapetum lucidum* in their choroid layer.*Please note; I'm not entirely sure about the spelling of tapetum lucidum. It could be spelled tapetum lucidium, tapetum ludicium, or any other variant, so don't go strictly by this answer! Most dictionaries have just tapetum.
