Those species with well-developed parotid glands at the back of the head, such as the Mole, Spotted, and Spiny Salamanders ( Ambystoma spp.), often adopt a posture where the head is bent down, thus presenting the attacker with a distasteful portion of the body. The distribution on the body of the toxin-secreting glands and warning coloration correlates well with the defensive posture adopted by the species in question.

35,36 Salamanders commonly practice tail autonomy as a defensive behavior (see tail displays in reptiles). Toads commonly inflate their lungs, puffing up the body and presenting a larger image to the predator, and at the same time often lift the body from the ground, tilting toward the predator. Death feigning and tonic immobility are widespread among frogs: some fold the limbs tightly against the body and lie motionless on their backs, and others assume a rigid posture with their limbs outstretched. This predatory pressure has led to the evolutionary development of antipredator mechanisms that often combine toxic secretions with unusual defensive postures and warning coloration. Salamanders, newts, and anurans (frogs and toads) are attacked and eaten by many different types of predators including birds, reptiles, mammals, and other amphibians.
