Drought is tough on insect eaters
The color-changing lizards commonly known as chameleons are always fun to watch. Especially fascinating is how these agile, long-tailed lizards switch from dull brown when perched on a wood post to bright green when they move to a leaf.
These lizards are anoles (pronounced ah-NO-lees).... | <urn:uuid:550b2f0c-3cdc-4f2a-955a-9b57c130937e> | 2.546875 | 973 | Nonfiction Writing | Science & Tech. | 49.911748 | 95,596,012 |
