对大多数动物来说，反捕食者的行为至关重要，需要准确的时间和迅速的动作。虽然快速的反应时间和可预测的，上下文相关的，逃生启动距离是大多数逃生系统的共同特征，以前的工作已经强调了逃生方向的不可预测性，以防止捕食者学习重复的，固定的模式。最终的不可预测性将来自随机的逃逸轨迹。虽然这种策略会剥夺捕食者的任何预测能力，但它也会导致一些逃离威胁的轨迹。先前的研究表明，逃逸轨迹实际上通常是远离威胁的，尽管具有很高的可变性。然而，支配这种变化的规则在很大程度上是未知的。在这里，我们证明了t个人蟑螂（美洲大蠊，一个被研究的模型猎物物种）保持每次逃跑不可预测的运行沿着一组首选的轨迹之一，在固定的角度从威胁刺激的方向。这些结果提供了一个新的范例，了解逃避反应的行为策略，强调需要重新审视蟑螂和类似动物模型中控制逃跑方向的神经机制，以及驱动不可预测的进化力量，或“多变”，反捕食者行为。
Anti-predator behaviour is vital for most animals, and calls for accurate timing and swift motion. While fast reaction times and predictable, context-dependent, escape initiation distances are common features of most escape systems, previous work has highlighted the need for unpredictability in escape directions, in order to prevent predators from learning a repeated, fixed pattern. Ultimate unpredictability would result from random escape trajectories. Although this strategy would deny any predictive power to the predator, it would also result in some escape trajectories towards the threat. Previous work has shown that escape trajectories are in fact generally directed away from the threat, although with a high variability. However, the rules governing this variability are largely unknown. Here, we demonstrate tha t individual cockroaches (Periplaneta americana, a much studied model prey species) keep each escape unpredictable by running along one of a set of preferred trajectories at fixed angles from the direction of the threatening stimulus. These results provide a new paradigm for understanding the behavio ural strategies for escape responses, underscoring the need to revisit the neural mechanisms controlling escape directions in the cockroach and similar animal models, and the evolutionary forces driving unpredictable, or “protean”, anti-predator behaviour.
