Los ojos que brillan en la oscuridad de la noche son para muchos una historia de miedo. Pero, ¿por qué los ojos de los lobos brillan en la oscuridad?

Wolves have a special light-reflecting surface right behind their retinas called the tapetum lucidum that helps animals see better in the dark. When light enters the eye, it’s supposed to hit a photoreceptor that transmits the information to the brain. But sometimes the light doesn’t hit the photoreceptor, so the tapetum lucidum acts as a mirror to bounce it back for a second chance. Cool!
