While the ant suffers predation by birds, amphibians, reptiles, insects, spiders and other organisms, it must see the horned lizard, the so-called “horny toad,” as a dragon. The colony that faces a horned lizard feeding on the ants near the entrance to the nest may mount a swarming attack against the menacing ogre. “A [horned] lizard besieged but determined to stay will remain motionless as dozens of ants crawl over its scaly armor, biting and stinging as they go,” said Taber. Unfortunately for the ants, the horned lizards have “an immunity or defense against ant venom in the form of a detoxifying substance in their blood plasma…, and when mobbed they simply hunker down with closed eyes until the ants leave.” The horned lizards then simply resume feeding. The ant colony may suffer considerable losses to a persistent lizard.

We need to import more of them, I think.
