动物对身体约束的普遍反应是强直不动。作者观察了吊带蛇（Thamnophis elegans）在野外的行为，以确定其不动的频率作为对处理的反应。大多数蛇在释放后逃跑，但其余的保持不动，有时仰卧（旋后），长达10分钟。不动最常见于怀孕的蛇，它们在被捕获前不动的可能性也比其他蛇大。在被捕获之前或之后不能移动，可能是怀孕蛇的运动能力有限的结果。然而，缺乏对蛇和它们的天敌之间相互作用的观察，阻碍了研究人员对抗捕食者价值的理解，如果有的话，补品不动。
A common response of animals to physical restraint is tonic immobility. The authors observed, the behavior of garter snakes, Thamnophis elegans, in the field to determine the frequency of immobility as a response to handling. Most snakes fled after release, but the remainder remained immobile, sometimes on their backs (supination), for up to 10 min. Immobility was seen most often in pregnant snakes, which also were more likely than other snakes not to have moved before capture. Failure to move, either before or after capture, might be a consequence of the limited locomotory ability of gravid snakes. However, the lack of observations of interactions between snakes and their natural predators impedes researchers' understanding of the antipredator value, if any, of tonic immobility.
