Dangerous Creatures: Desert Environments

   Water. That’s the challenge in the desert.
   The Australian outback. In this isolated area, some primitive mammals have changed very, very little.
   The green toad has special features that help it cope with a lack of water.
   Get along where you are when you can. But if times get really rough, if you’re a locust, you know you can just fly away.
   How to avoid the daytime desert heat? Why, go underground, of course!
   Some creatures don’t need to look for water. Their bodies take care of that for them.
   Video: From a hawk’s point of view, the desert is a good place to live. There’s a lot of room to fly, and saguaro cacti make fine perches to sit on. And prey can be easily spotted from great distances. From a rabbit’s viewpoint, there aren’t many places to hide.
   Advice: Lots of desert creatures have special skins that prevent moisture from escaping. When I’m in the desert, I wish I had this skin as well!

Next: There’s more life in a desert environment than you might expect. In the American Southwest, you might find a cougar.
