From digestive secrets to high-speed travel, here are ten reasons why reindeer are the coolest animals on the planet.
The Eyes That Shift With Seasons
Reindeer are the only mammals known to change their eye color to adapt to the shifting light of the changing seasons. During the golden days of summer, their eyes appear a shimmering gold color to reflect the constant, intense Arctic sunlight. This clever biological trick helps them navigate the bright landscape without damaging their sensitive retinas or losing sight of potential predators lurking nearby.
However, once the deep winter “polar night” descends, their eyes undergo a radical transformation and turn a deep, mystical blue. This shift happens because the pressure in the eye increases, packing the collagen fibers in the tapetum lucidum more tightly together. It is an incredible evolution that allows them to capture every single stray photon of light in the darkness, making their night vision legendary.
According to studies from University College London, this color change is vital for spotting lichen and predators when the sun never rises. Can you imagine your eyes physically changing hue just because the clocks turned back? It is one of those facts about reindeer that sounds like science fiction but is actually a genius survival tactic for the brutal, dark months of the Far North.
