轉(zhuǎn)移注意力是魔術(shù)教科書和軍事策略中最古老的把戲,，如今,，一項發(fā)表在《當(dāng)代生物學(xué)》（Current Biology）上的研究表明,，魚類可能也會使用這招。
據(jù)美國《科學(xué)》雜志在線新聞報道,，雄大西洋帆鰭鱸一直喜歡體型較大的雌魚,，然而當(dāng)研究人員讓這些雄魚在一些“觀眾”——一群能夠看到卻無法干涉的位于玻璃后面的雄魚——的面前挑選配偶時，這些雄魚在很大程度上卻會忽略那些大的雌魚,，轉(zhuǎn)而接近那些小魚,。研究人員相信，這些雄大西洋帆鰭鱸假裝對那些小雌魚感興趣其實是為了迷惑競爭對手,。（生物谷Bioon.com）

Summary
A fundamental question in animal communication is whether the information provided is honest or deceptive [1, 2]. This problem has received much attention, both in theoretical [1, 3] and experimental [4] work. Here we show that male Atlantic mollies (Poecilia mexicana), when observed during mate choice by another male, reduce their mating activity and no longer prefer mating with one of two females presented, which can be interpreted as an attempt to avoid unintended interception of information by the rival male. Most importantly, focal males directed their first sexual interaction (after they were presented with the rival male) toward the initially nonpreferred female, suggesting that males deceive other males about their mating preferences. Deception by the choosing male may be an adaptation to avoid sperm competition, because surrounding males may use public information and copy the focal male's mate choice.
