寄居蟹可能通过与其他螃蟹交易或在捕食事件中获得新壳。捕食事件是通过与腹足类动物和同种动物死亡相关的气味进行化学定位的。螃蟹对这两种线索的反应都是一样的。本文报道了寄居蟹（Clibanarius vittatus）对腹足动物肉和同种血淋巴中的化学物质有三种不同的反应方式：(1)螃蟹不反应（23%），(2)螃蟹逃跑（40%），(3)螃蟹调查邻近的贝壳（37%）。改变壳的大小可以改变螃蟹的行为。通过减少壳的大小来改变壳的大小，导致高（大约）。80%)通过调查回应。给螃蟹自由选择空壳（86%）作为对化学刺激的反应而逃跑。在一系列实验中，研究人员测试了小螃蟹在化学刺激下的行为，然后让它们接触到多余的空壳。24小时后评估化学刺激行为。
Hermit crabs may acquire shells by trading with other crabs or at predation events that make new shells available. Predation events are located chemically through odors associated with the death of gastropods and the death of conspecifics. Crabs respond identically to either source of cues. Here we report that hermit crabs, Clibanarius vittatus from the field respond in one of three distinct ways to chemicals from gastropod flesh and from conspecific hemolymph: (1) crabs do not respond (23%), (2) crabs flee (40%), and (3) crabs investigate neighboring shells (37%). Changing the size of the shell can cause crabs to change behavior. Altering shell size by clipping down shells resulted in high (approx. 80%) response by investigation. Crabs given a free choice of unoccupied shells fled (86%) in response to chemical stimulation. In a series of experiments small crabs were tested for chemically‐stimulated behavior and then given access to excess empty shells. Chemically‐stimulated behavior was assessed after 24...
