Here’s a young regal horned lizard (Phrynosoma solare) just after squirting me, my phone, and my camera with blood from its eyes. They do this to scare off mamilian predators, which I guess means me. I must admit it worked, as unlike the a bite from the little guy, it got me to put him down to wipe the stuff off my glasses. If coyotes wore glasses, this defense would be air-tight.
