鱼群中的小鱼用一系列的行为来辨别梭子鱼的跟踪模式。捕食者的识别最初是基于模型的形状和大小，通过小鱼在捕食者检查期间收集的标记信息来确认识别。小鱼的行为表明，鱼群把最现实的模型视为最大的威胁。相反，在最不现实的模型中，重复秸秆中反捕食者反应的习惯化最为明显。讨论了捕食实验中模型设计的启示。
Minnows in shoals used a spectrum of behaviours to discriminate stalking models of pike. Predator recognition was initially based on model shape and size, with identification being confirmed using information on markings gathered by minnows during predator inspection visits. Minnow behaviour indicated that shoals regarded the most realistic model as the greates threat. Conversely, habituation of the anti-predator response in repeated stalks was most evident with the least realistic model. Implications for the design of models used in predation experiments are discussed.
