短文解析
本文介紹了幾種會(huì)放電的魚(yú)。放電的魚(yú)中，最為人所知的就是電鰩，它們腦部有一些細(xì)胞含有電板，觸摸電板的兩極就會(huì)放電，電擊的強(qiáng)度取決于魚(yú)的大小。還有一種著名的放電魚(yú)就是電鰻，電鰻的放電強(qiáng)度還要大一些。電鰻的電流是從頭部傳到尾部的，放電器官是變化的肌肉。尼羅河中的鯰魚(yú)和其他非洲淡水魚(yú)的導(dǎo)電途徑是從尾到頭，雖然電流強(qiáng)度不如前兩種魚(yú)，但也不怎么令人舒服。放電的能力為這些魚(yú)提供了防衛(wèi)和進(jìn)攻的本領(lǐng)，可以擊退強(qiáng)敵。
