Adapted to Survive

Individuals are great climbers and are often found in trees and bushes.

During winter, individuals go into a deep sleep called brumation (a type of dormancy in reptiles not as deep as hibernation); this adaptation allows them to endure the cold season.

Individuals can raise their body off the ground if threatened.
