Blue-tongue Lizard

Check out this short video of this Blue-tongue's defence strategy: https://youtu.be/mUP8jEPGlYw which is described as so: "The blue tongue's main defence strategy is bluff: It faces the threat and opens its mouth. The blue tongue inside the pink mouth is an unexpected and vivid sight, designed to frighten off the attacker. The lizard also hisses loudly and flattens its body which makes it look wider and bigger." (http://www.outback-australia-travel-secrets.com/blue-tongue-lizard.html )
