The short-tailed horned lizard is a small lizard with sharp horns on its head. It inhabits dry areas of Mexico and defends itself from enemies in an unusual way—by squirting blood from its eyes.
The short-tailed horned lizard differs from its relatives by its very short tail and a special defense method using blood from its eyes. It helps control ant populations in nature and serves as food for snakes and birds.
