Whenever the Australian frilled lizard (a member of the dragon family) feels threatened, it stands on its hind legs, opens its mouth and expands a flap of skin that creates a circle around its head. If that doesn’t intimidate its predator, it turns and scurries off with its frill still wide open.
This circle of frill, not only helps in the warding-off-others department, but it also can be used to help the lizard regulate its body temperature. Because of these attributes, I think the frilled lizard is truly inspiring: Can you imagine if you could scare others off like this on those days when you’re simply not in the mood to talk? That would be a sight to see!
