Depending on the species and circumstances, a nonpoisonous snake may react in one of several ways when threatened: it may lay on its back and play dead, hiss, open its mouth in a threatening manner, coil and strike, or bite (non-poisonous snakes have several rows of short recurved teeth) Snakes are cold-blooded and must move to a suitable surrounding environment to regulate their body temperature.
