Why do some animals' eyes seem to glow in the dark? 👀✨
That's thanks to a reflective layer in the back of the eye called the tapetum lucidum, which in Latin means "tapestry of light" or "bright tapestry." It acts like a mirror, bouncing light back through the retina and helping animals see more clearly at night.
It might look a little mysterious, but it's actually one of nature's many brilliant adaptations for life after dark.
