Skinks are small: most can only grow to be 12cm long. Some can grow to be 35cm. A trait of skinks is a love of digging and burrowing. Underground they are mostly safe from predators. Sometimes they dig tunnels for easy navigation. They also use their tongues to sniff the air and track their prey. When they encounter their prey, they chase it down until they corner it or manage to land a bite and then swallow it whole. Some skinks live in trees. If they do, then they usually have longer fingers.
