A light-reflecting layer on a wolf’s eye called the tapetum lucidum (Latin for “bright tapestry”) causes a wolf’s eyes to glow in the dark and may also facilitate night vision. While a wolf’s color perception and visual acuity maybe be inferior to a human’s, a wolf’s eyes are extremely sensitive to movement.
........Aún cuando no puede ver en la oscuridad absoluta, posee detrás de su retina un tejido reflectante llamado "tapetum lucidum" que le permite distinguir lo que lo rodea, cuando la luz es tan reducida que impide la visión para el hombre y a otros animales menos dotados en este aspecto que los felinos.
These cats are typically active and playful, even as adults, and are often described as more dog-like in behavior than other cats. They are sometimes less active at night than most cats, possibly because the lack of a tapetum lucidum gives them poor night sight relative to other cats.
an alligator has a tapetum lucidum at the back of each eye, which reflects light back into the photoreceptor cells to make the most of low light. the colour of eyeshine differs from species to species, but in alligators glows red. the length of the alligator can be approximated by judging the distance between the eyes, making this alligator very long. photo by larry lynch
The eyes of some animals appear to shine in the dark. This is due to the tapetum lucidum, a layer of material that helps animals see in the dark—like cats, who can see six to eight times better than humans in dim lighting: https://curiosity.com/video/why-do-some-animals-eyes-shine-in-the-dark-brain-stuff/?utm_source=pinterest&utm_medium=social&utm_campaign=112414shinyeyespin
Red Eye by Larry Lynch: Like cats, an alligator has a tapetum lucidum at the back of each eye - a structure that reflects light back into the photoreceptor cells to make the most of low light. The colour of eyeshine differs from species to species. In alligators, it glows red - one good way to locate alligators on a dark night. The greater the distance between its eyes, the longer the reptile, in this case, very long.via telegraph.co.uk #Alligator #Vision #Larry_Lynch #telegraph_co_uk
