Abstract

When encountering predators, prey animals often expose themselves by loud vocalization, by repeated movements or by revealing conspicuous colors. The more elaborate displays were often considered to be warning signals directed to other prey, and the less obvious displays to be intention movements. During the last decade, there has been increasing evidence that, in fact, prey display is aimed at the predator, apparently to deter further pursuit. This communication between two seemingly unlikely partners, prey and predator, appears to be based upon a common interest - satisfying the predator's need for further information.

摘要

当遇到捕食者时,猎物动物通常会通过大声发声、重复动作或展示显眼的颜色来暴露自己。更精心制作的展示通常被认为是针对其他猎物的警告信号,而不太明显的展示则被视为意图动作。在过去的十年中,越来越多的证据表明,事实上,猎物的展示是针对捕食者的,显然是为了阻止进一步的追捕。这种来自两个看似不太可能的伙伴——猎物和捕食者之间的交流,似乎是基于一种共同的利益——满足捕食者对进一步信息的需求。
