Cheetahs wear naturally occurring sunglasses
The black tear streaks on this cat’s face absorb the Sun’s rays to deflect glare away from the eyes. This is vital for maintaining the cat’s visual contact with faraway prey. Black fur absorbs light of every wavelength and reflects none. Conversely, lions have white stripes beneath their eyes to increase the amount of light that enters them as white is a highly reflective shade. Cheetahs hunt by day and lions are mostly active at night, and both species have evolved to deal with sunlight with facial colouration.
“Patterned fur breaks up the cheetah’s outline and enables it to sneak through vegetation without becoming visible”
