2. Blood squirters
The Texas horned lizard will squirt blood out of its eyes when faced with a predator. The two muscles around the major blood vessel in its eye contract and cut off blood to the heart and allowing it to build up in the head. The pressure builds in the ocular sinus until the membrane is ruptured, shooting a jet stream of blood that can reach up to 4 feet! It doesn’t harm the reptile and it can be repeated multiple times without harming the lizard.
