Horned Toad Lizard

The horned toad lizard lives in the North American desert. Now there is a reason for it having horns on its back. Well for one reason it makes it harder for other creatures to chomp it. And another reason is this: tiny, itsy-bitsy drops of dew are lead into its mouth by the horns. They make a trail that leads to a corner of its mouth. And it's a pretty fast creature too. It is a good sprinter. And on the plus side, it can camouflage.
