The Texas Horned Lizard is a scary-looking creature. Brown, plump and perfectly camouflaged in its native sandy environment, its first line of defense is its spiky demeanor. If the sharp spikes and horns don’t ward of predators, the lizard steps it up a notch and squirts a well-aimed stream of blood out of its eyes.
The stream of blood, which can go as far as 5 feet, is mixed with a foul-tasting chemical that wards off predators. But as with the hairy frog, this odd weapon comes at a cost: The lizard may release a third of its total blood supply this way, amounting to two percent of its body mass.
