The lizard known for shooting blood from its eyes as a defense mechanism is the Horned Lizard, also commonly referred to as the Horned Toad (genus Phrynosoma). This unique and fascinating behavior is a form of self-defense against predators.
When threatened, the Horned Lizard can intentionally rupture tiny blood vessels near its eyes. The blood is then forced out through the corners of its eyes, and the stream of blood can be directed towards the predator. This serves as a deterrent, as the blood has a foul taste and can be irritating to predators, providing the lizard with a chance to escape.
It's worth noting that while this defense mechanism is effective against some predators, it may not work against all, and the loss of blood can be a stressful experience for the lizard
