How cool is this? Apparently tigers have eyespots on their back as a form of mimicry to warn off any potential predators/attackers (not that tigers have many).
A daily occurrence that leaves tigers particularly vulnerable is when they lower their heads to get a drink of water. By having these eyespot markings on their fur, potential attackers may think twice about an ambush.
Below you can see another example of these fascinating eyespots. Nature is amazing!
