Did You Know?
Lizards, including the colorful collared lizard, are one of the most frequently seen animals at Arches. When not chasing flies or basking in the sun, they are often seen doing what appears to be push-ups. This odd dance might enhance their stereoscopic vision, helping them see what's looking back at them.
