If debilitated prey items can be caught more efficiently than healthy ones, there is a selective advantage for predators to detect any weakness in their prey. This study investigates whether three-spined sticklebacks (Gastcrosteus aculeatus L.) accustomed to feeding on one or the other of two types of waterfleas differing in their swimming pattern capture the unfamiliar type when given a choice. Such sequential oddity selection might serve as a mechanism for the detection of sick prey.
