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.
Raccoons are thought to be color blind or at least poorly able to distinguish color, though their eyes are well-adapted for sensing green light. [ 116 ] [ 117 ] [ 118 ] Although their accommodation of 11 dioptre is comparable to that of humans and they see well in twilight because of the tapetum lucidum behind the retina , visual perception is ...
The eyes of some bivalve mollusks, such as the scallop (Pecten) use a concave mirror, the argentea, at the back of the eye, to create an image on the retina. The deep-sea ostracod Gigantocypris has eyes with parabolic reflectors. The compound eyes of long-bodied decapod crustaceans, such as shrimps and lobsters, use mirrors in square boxes [1]
A raccoon's eyes brightly reflect a camera flash. The light from the eyes of some animals (such as cats, which modern science has determined have highly reflective eyes) could also be seen in "darkness". Adherents of intromission theory countered by saying that if emission theory were true, then someone with weak eyes should have their vision ...

Adult raccoons weigh about 35 pounds and measure 3 feet long from nose to tail. Raccoons are most active morning, evening, and night. The masks on their faces reduce glare and assist in night vision.
Animal colouration is the general appearance of an animal resulting from the reflection or emission of light from its surfaces. Some animals are brightly coloured, while others are hard to see. Some animals are brightly coloured, while others are hard to see.
While the spectrum of eye colors is as vast as the human experience itself, one of them is the rarest eye color in the world that only a small percentage of the population possess.
