Horned lizards shoot blood from their eyes, which is weird! A horned lizard is a one-reptile wrecking crew with a bizarre self-defense strategy who sits motionless in the desert sun, eyeing a young coyote skulking nearby.
Their unusual defense mechanism involves the flooding of their ocular sinuses, tissues found below their eye, with blood. When a horned lizard feels threatened by a predator, its final defense response is to shoot blood from these flooded sinuses and out its eye sockets. As a result, the predator is often frightened and flees.
