PULLMAN, Wash. – There’s something about a chameleon’s darting eyes, long tongue, curled tail and ability to climb that makes it a fascinating animal to watch. Especially when it’s changing colors.
And the latest research suggests that how a chameleon changes has more to do with light than scientists once thought.
That’s what I learned from my friend Paul Verrell, a biologist at Washington State University who studies animal behavior and works with reptiles. He said not all chameleons change colors. They also don’t necessarily use their colors to hide from predators.
