由群体效应引起的紧急行为是集体动物群体最引人注目的方面之一。调查这种行为对于了解个人如何与邻居互动非常重要。虽然有许多实验使用集体动物来研究社会学习或个人与社会之间的冲突，例如鱼与学校之间的冲突，但关于群体效应的报道很少。在这项研究中，我们表明，一群士兵蟹可以自发地进入水池，这通常是避免的，形成密集的一群在水池边缘的一部分。此外，我们发现，所观察到的行为可以解释的集体行为模型的基础上的固有噪声，即个人的不同速度在一个有向群体。我们的研究结果表明，固有的噪音，这是广泛存在于集体动物，可以有助于形成和/或维护的一个群，密集的群可以进入池通过增强的固有噪音。
Emergent behavior that arises from a mass effect is one of the most striking aspects of collective animal groups. Investigating such behavior would be important in order to understand how individuals interact with their neighbors. Although there are many experiments that have used collective animals to investigate social learning or conflict between individuals and society such as that between a fish and a school, reports on mass effects are rare. In this study, we show that a swarm of soldier crabs could spontaneously enter a water pool, which are usually avoided, by forming densely populated part of a swarm at the edge of the water pool. Moreover, we show that the observed behavior can be explained by the model of collective behavior based on inherent noise that is individuals’ different velocities in a directed group. Our results suggest that inherent noise, which is widely seen in collective animals, can contribute to formation and/or maintenance of a swarm and that the dense swarm can enter the pool by means of enhanced inherent noise.
