Lizard Shoots Blood Out Of Eye As Defense Mechanism (VIDEO)

This is one lizard that you wouldn't want to make angry.

While it may look harmless enough using its quick tongue to snatch up helpless ants, which make up 90% of its diet according to National Geographic, it brings out the big guns when threatened with becoming someone's dinner.

No, that bright red substance that this horned lizard can literally shoot from its eye in a pressurized jet isn't poisonous; it's just plain, old blood. But that blood is enough to freak out most foes.

See what happens when this lizard uses its secret weapon on a coyote in this video from National Geographic.
