This Lizard’s Tongue Is Its Secret Weapon

What animal flashes its tongue to scare off predators?

Meet the northern blue tongue skink, a reptile that’s mastered the art of the fake-out. When danger approaches, it opens its mouth, hisses loudly, and sticks out its electric-blue tongue in a startling move known as a “deimatic display”. This bluff is designed to confuse predators just long enough for the skink to scurry to safety. It's an incredible example of how animals evolve visual and auditory adaptations for survival.
