Mantis shrimp of the species occupy small burrows in shallow waters throughout the Caribbean. These animals use path integration, a vector-based navigation strategy, to return to their homes while foraging. Here, we report that path integration in is prone to error accumulated during outward foraging paths and we describe the search behavior that employs after it fails to locate its home following the route provided by its path integrator. This search behavior forms continuously expanding, non-oriented loops that are centered near the point of search initiation. The radius of this search is scaled to the animal's positional uncertainty during path integration, improving the effectiveness of the search. The search behaviors exhibited by bear a striking resemblance to search behaviors in other animals, offering potential avenues for the comparative examination of search behaviors and how they are optimized in disparate taxa.
鼓虾物种生活在加勒比海的浅水中，占据着小洞穴。这些动物在觅食时使用基于向量的路径整合导航策略返回自己的巢穴。在这里，我们报告说，在向外觅食的过程中，路径整合容易出现误差累积，并且我们描述了 在未能按照路径积分器提供的路线找到家时所采用的搜索行为。这种搜索行为形成了不断扩大的、无方向的循环，以搜索起始点为中心。搜索半径与动物在路径整合过程中的位置不确定性成比例，从而提高了搜索的有效性。 表现出的搜索行为与其他动物的搜索行为非常相似，为比较不同分类群的搜索行为及其优化方式提供了潜在途径。
