Eyeshine or tapetum lucidum is when an animal's eyes glow in the dark.
When light goes into the animal's eye, it hits a web of cells called the tapetum behind the light collector. These cells reflect the light like a mirror. The light goes through the animal's light collector twice, once on the way in and once on the way out. This helps the animal see in the dark.[1]
Most animals with eyeshine are animals with fur, but bullfrogs and some spiders have eyeshine too.
Different animals' eyes glow different colors:
- Alligator - red-orange
- Deer - green
- Cat - gold or green
- Barred owl - bright red[2]
