Fish are socially intelligent creatures who do not deserve their reputation as the dim-wits of the animal kingdom, according to a group of leading scientists. 

    Rather than simply being instinct-driven, the group says fish are cunning, manipulative and even cultured. 

    The three experts from the universities of Edinburgh, St Andrews and Leeds said there had been huge changes in science's understanding of the psychological and mental abilities of fish in the last few years. 

    Writing in the journal Fish and Fisheries, biologists Calum Brown, Keven Laland and Jens Krause said fish were now seen as highly intelligent creatures. 

    They said: "Gone (or at least obsolete) is the image of fish as drudging and dim-witted pea-brains, driven largely by 'instinct', with what little behavioural flexibility they possess being severely hampered by an infamous 'three-second memory'. 

    "Now, fish are regarded as steeped in social intelligence, pursuing Machiavellian strategies of manipulation, punishment and reconciliation, exhibiting stable cultural traditions, and co-operating to inspect predators and catch food." 

    Recent research had shown that fish recognised individual "shoal mates", social prestige and even tracked relationships. 

    Scientists had also observed them using tools, building complex nests and exhibiting long-term memories. 

    The scientists added: "Although it may seem extraordinary to those comfortably used to pre-judging animal intelligence on the basis of brain volume, in some cognitive domains, fishes can even be favourably compared to non-human primates." 

    They said fish were the most ancient of the major vertebrate groups, giving them "ample time" to evolve complex, adaptable and diverse behaviour patterns that rivalled those of other vertebrates. 

    "These developments warrant a re-appraisal of the behavioural flexibility of fishes, and highlight the need for a deeper understanding of the learning processes that underpin the newly recognised behavioural and social sophistication of this taxon," said the scientists. 

    一批杰出的科學(xué)家認(rèn)為，魚(yú)是具有社會(huì)智商的動(dòng)物，它們不應(yīng)被稱為動(dòng)物王國(guó)中的笨蛋。 

    研究組的科學(xué)家們說(shuō)，魚(yú)類不是簡(jiǎn)單地憑本能行事，它們很機(jī)靈，有控制能力，甚至很有教養(yǎng)。 

    三位來(lái)自愛(ài)丁堡、圣·安德魯斯和利茲大學(xué)的專家說(shuō)，科學(xué)界在最近幾年里對(duì)魚(yú)的心理和心智能力的認(rèn)識(shí)發(fā)生了巨大的變化。 

    生物學(xué)家富勒姆·布朗、凱文·萊蘭和延斯·克勞斯在《魚(yú)類和漁業(yè)》雜志上發(fā)表文章說(shuō)，目前魚(yú)被認(rèn)為是非常聰明的動(dòng)物。 

    他們說(shuō)：“過(guò)去魚(yú)類被看作單調(diào)乏味、腦袋只有豌豆大的笨蛋，只會(huì)受‘本能’驅(qū)使，僅有的一點(diǎn)兒行動(dòng)靈活性也被它那臭名昭著的‘三秒鐘記性’嚴(yán)重阻礙了。如今這種說(shuō)法已經(jīng)一去不返了（或者至少是過(guò)時(shí)了）。” 

    “現(xiàn)在，魚(yú)被認(rèn)為充滿著社會(huì)智商，運(yùn)用馬基雅維利式的策略，諸如操縱、懲罰和順從，表現(xiàn)出固有的文化傳統(tǒng)，并通過(guò)合作來(lái)勘查敵情和捕捉食物。” 

    最近的研究表明魚(yú)可以識(shí)別各自的魚(yú)群伙伴，社會(huì)威望，甚至相關(guān)的人際關(guān)系。 

    科學(xué)家們也觀察到它們會(huì)使用工具，修筑結(jié)構(gòu)復(fù)雜的窩，還表現(xiàn)出長(zhǎng)期的記憶力。 

    科學(xué)家們補(bǔ)充說(shuō)：“盡管對(duì)于那些習(xí)慣于以腦容量來(lái)事先判斷動(dòng)物智商的人來(lái)說(shuō)這看起來(lái)非常特別，但是在某些認(rèn)知領(lǐng)域，魚(yú)甚至可以和人類以外的靈長(zhǎng)類動(dòng)物相媲美。” 

    他們說(shuō)魚(yú)是最古老的主要脊椎動(dòng)物，他們有"足夠多的時(shí)間"來(lái)進(jìn)化出復(fù)雜多樣并且有適應(yīng)能力的行為模式，與其他脊椎動(dòng)物相抗衡。 

    科學(xué)家們說(shuō)：“這些進(jìn)化就是重新評(píng)價(jià)魚(yú)類行為靈活性的有力依據(jù)，并且突出了有必要進(jìn)一步了解魚(yú)類剛被認(rèn)可的行為和社交復(fù)雜性的進(jìn)化過(guò)程。”
