Here's one reason. It's Hernan the Horned Lizard! Although many people call him "horny toad," he's not a toad, as you can see by his scaly skin and tail. Horned lizards like Hernan are protected in Texas. It's illegal to collect them or hurt them. Hernan loves the hot, dry Scrub. And he loves ants. In fact, ants are about all he eats. When people kill the ants with pesticides, they kill Hernan too.
