The answer is false. Based on the research that I just did, it seems that their leaf-like appearance is only used for camouflage. There was no mention of it being used to find food, but they do have a very keen sense of direction.

It bears repeating that reptiles potentially dangerous to man account for only a small proportion of Nevada’s herpetofauna. Of the twenty-five snake species found here, only the six rattlesnakes pose any possible threat. Similarly, of twenty lizard species native to Nevada, only the Gila monster is venomous. The vast majority of reptiles found in Nevada (and elsewhere) are completely harmless!
