電(dian)鰩科(ke)(Torpedinidae)、單鰭電(dian)鰩科(ke)(Narkidae)、無(wu)鰭電(dian)鰩科(ke)(Temeridae)魚類的統稱(cheng)，以(yi)能發電(dian)傷人(ren)而聞名。見于世界熱(re)、溫帶水(shui)域。種類多，多棲於(wu)淺水(shui)，但深(shen)海電(dian)鰩屬(shu)(Benthobatis)等(deng)可(ke)生活於(wu)1,000公尺(3,300呎(chi))以(yi)下的深(shen)水(shui)。活動緩(huan)慢，底棲，以(yi)魚類及無(wu)脊椎動物為食。如不被觸及則對人(ren)無(wu)害，經濟價值微不足道。

軟骨魚(yu)綱電(dian)(dian)鰩目(mu)是板腮(sai)(sai)類魚(yu)的(de)一個目(mu)，此目(mu)的(de)魚(yu)腮(sai)(sai)裂和口都(dou)在(zai)(zai)腹位，有(you)五(wu)個腮(sai)(sai)裂，身體平扁卵(luan)圓(yuan)形，吻不(bu)突(tu)出，臀(tun)鰭(qi)(qi)消失，尾鰭(qi)(qi)很小(xiao)，胸鰭(qi)(qi)寬大，胸鰭(qi)(qi)前緣和體側相連(lian)接(jie)。在(zai)(zai)胸鰭(qi)(qi)和頭之間的(de)身體每(mei)側有(you)一個大的(de)發(fa)電(dian)(dian)器官，能發(fa)電(dian)(dian)，以電(dian)(dian)擊敵人或獵(lie)物(wu)，卵(luan)胎生，分(fen)布在(zai)(zai)熱帶和亞熱帶近海(hai)，半埋在(zai)(zai)泥沙中等待獵(lie)物(wu)，一般(ban)體形較小(xiao)，沒有(you)食用價值。根(gen)據(ju)背鰭(qi)(qi)的(de)多少，分(fen)為三科：
電(dian)(dian)(dian)(dian)(dian)(dian)鰩(yao)最大(da)的(de)(de)(de)(de)個(ge)(ge)體可以達到2米,很(hen)少在(zai)0.3米以下。背腹扁平,頭(tou)和胸(xiong)部(bu)(bu)(bu)在(zai)一起(qi)。尾(wei)部(bu)(bu)(bu)呈粗棒狀,像(xiang)團扇。電(dian)(dian)(dian)(dian)(dian)(dian)鰩(yao)棲居在(zai)海底,一對小眼長在(zai)背側面(mian)(mian)(mian)前(qian)方的(de)(de)(de)(de)中間(jian)。在(zai)頭(tou)胸(xiong)部(bu)(bu)(bu)的(de)(de)(de)(de)腹面(mian)(mian)(mian)兩(liang)側各有一個(ge)(ge)腎(shen)臟形蜂窩(wo)狀的(de)(de)(de)(de)發電(dian)(dian)(dian)(dian)(dian)(dian)器。它(ta)們排列成六角柱體，叫“電(dian)(dian)(dian)(dian)(dian)(dian)板(ban)(ban)”柱。電(dian)(dian)(dian)(dian)(dian)(dian)鰩(yao)身上共有2000個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)(dian)板(ban)(ban)柱，有200萬塊“電(dian)(dian)(dian)(dian)(dian)(dian)板(ban)(ban)”。這些電(dian)(dian)(dian)(dian)(dian)(dian)板(ban)(ban)之(zhi)間(jian)充滿(man)膠質(zhi)狀的(de)(de)(de)(de)物質(zhi)，可以起(qi)絕緣作用(yong)。每個(ge)(ge)“電(dian)(dian)(dian)(dian)(dian)(dian)板(ban)(ban)”的(de)(de)(de)(de)表面(mian)(mian)(mian)分布有神經末梢，一面(mian)(mian)(mian)為(wei)負電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)，另一面(mian)(mian)(mian)則為(wei)正電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)方向(xiang)是從(cong)(cong)正極(ji)流(liu)到負極(ji)，也就是從(cong)(cong)電(dian)(dian)(dian)(dian)(dian)(dian)鰩(yao)的(de)(de)(de)(de)背面(mian)(mian)(mian)流(liu)到腹面(mian)(mian)(mian)。在(zai)神經脈沖的(de)(de)(de)(de)作用(yong)下，這兩(liang)個(ge)(ge)放電(dian)(dian)(dian)(dian)(dian)(dian)器就能把神經能變成為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)能，放出電(dian)(dian)(dian)(dian)(dian)(dian)來(lai)。單(dan)個(ge)(ge)“電(dian)(dian)(dian)(dian)(dian)(dian)板(ban)(ban)”產生(sheng)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓很(hen)微(wei)弱，可是，由于數量很(hen)多，就能發出很(hen)強(qiang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓來(lai)。電(dian)(dian)(dian)(dian)(dian)(dian)鰩(yao)的(de)(de)(de)(de)每一個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)(dian)板(ban)(ban)，只(zhi)是肌纖維的(de)(de)(de)(de)變態(tai)。發電(dian)(dian)(dian)(dian)(dian)(dian)器官是從(cong)(cong)某些鰓肌演(yan)變而來(lai)的(de)(de)(de)(de)。在(zai)演(yan)變發生(sheng)過程中解除(chu)了腮肌原(yuan)來(lai)的(de)(de)(de)(de)職務，而承擔(dan)了新的(de)(de)(de)(de)作用(yong)——發電(dian)(dian)(dian)(dian)(dian)(dian)。
自我保護
發(fa)電器最主要的(de)(de)樞紐，是器官的(de)(de)神(shen)經部分，電鰩能隨(sui)意放電，放電時間和強度，它完全能夠自己(ji)掌握。電鰩可以發(fa)電,并靠發(fa)出的(de)(de)電流(liu)擊斃水中的(de)(de)小魚、蝦及其他的(de)(de)小動物(wu),是一種捕食(shi)和打(da)擊敵害的(de)(de)手段。
世界上(shang)有好(hao)多種(zhong)電(dian)(dian)(dian)鰩(yao)(yao),其發(fa)電(dian)(dian)(dian)能力各(ge)不相同。非洲(zhou)電(dian)(dian)(dian)鰩(yao)(yao)一次(ci)發(fa)電(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)壓(ya)在220伏左右,中等(deng)大(da)小的(de)(de)(de)電(dian)(dian)(dian)鰩(yao)(yao)一次(ci)發(fa)電(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)壓(ya)在70～80伏,像較小的(de)(de)(de)南美電(dian)(dian)(dian)鰩(yao)(yao)一次(ci)只(zhi)能發(fa)出(chu)37伏電(dian)(dian)(dian)壓(ya)。由于電(dian)(dian)(dian)鰩(yao)(yao)會發(fa)電(dian)(dian)(dian)，人們叫它做活的(de)(de)(de)發(fa)電(dian)(dian)(dian)機、活電(dian)(dian)(dian)池、電(dian)(dian)(dian)魚等(deng)。
電(dian)(dian)鰩(yao)可以放出50安培的電(dian)(dian)流，電(dian)(dian)壓(ya)達60～80伏，有海中(zhong)“活電(dian)(dian)站”之稱。電(dian)(dian)鰩(yao)每(mei)秒鐘(zhong)能放電(dian)(dian)50次，但(dan)連續放電(dian)(dian)后(hou)(hou)，電(dian)(dian)流逐(zhu)漸減弱，10～15秒鐘(zhong)后(hou)(hou)完(wan)全消失，休息(xi)一會后(hou)(hou)又能重新恢復放電(dian)(dian)能力。
電鰩的(de)放電特性啟發(fa)人們(men)發(fa)明和創(chuang)造了能貯(zhu)存電的(de)電池。人們(men)日常生活中所用的(de)干電池，在正(zheng)負(fu)極間的(de)糊狀填充物(wu)，就是(shi)受電鰩發(fa)電器里的(de)膠狀物(wu)啟發(fa)而改進的(de)。
早(zao)在(zai)古希(xi)臘和(he)(he)羅(luo)馬時代，醫生們常常把病(bing)人(ren)放(fang)到(dao)電鰩(yao)身上，或者(zhe)讓病(bing)人(ren)去碰一下正在(zai)池中(zhong)放(fang)電的電鰩(yao)，利用電鰩(yao)放(fang)電來治(zhi)療風濕(shi)癥和(he)(he)癲狂癥等病(bing)。就是到(dao)了今天，在(zai)法(fa)國和(he)(he)意大(da)利沿海(hai)(hai)，還可能看(kan)到(dao)一些患有風濕(shi)病(bing)的老年人(ren)，正在(zai)退潮(chao)后(hou)的海(hai)(hai)灘上尋找(zhao)電鰩(yao)，當做自(zi)己的“醫生”呢。
放電原因
1989年，在法國科學城舉(ju)辦了一次饒(rao)有趣味的(de)“時鐘(zhong)(zhong)”回(hui)顧展(zhan)覽，一座用帶(dai)電(dian)(dian)(dian)魚放(fang)出的(de)電(dian)(dian)(dian)來驅動(dong)的(de)時鐘(zhong)(zhong)，引(yin)起了人(ren)們極大的(de)興趣。這種帶(dai)電(dian)(dian)(dian)魚放(fang)電(dian)(dian)(dian)十分有規律，電(dian)(dian)(dian)流的(de)方向一分鐘(zhong)(zhong)變換一次，因而被(bei)人(ren)稱為“天然報時鐘(zhong)(zhong)”。常見(jian)的(de)帶(dai)電(dian)(dian)(dian)魚有電(dian)(dian)(dian)鰻、電(dian)(dian)(dian)鰩、電(dian)(dian)(dian)鯰等(deng)。其中電(dian)(dian)(dian)鰩電(dian)(dian)(dian)力第二強了。 它放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)壓可達300～500伏，足(zu)以(yi)把附近的(de)魚電(dian)(dian)(dian)死，人(ren)和牲畜(chu)碰上，全(quan)身也會麻痹。據計算，1萬條電(dian)(dian)(dian)鰩的(de)電(dian)(dian)(dian)能(neng)聚集在一起，足(zu)夠使1列(lie)電(dian)(dian)(dian)力機(ji)車運(yun)行幾分鐘(zhong)(zhong)。
放電原理
原來(lai)，電(dian)(dian)(dian)(dian)鰩(yao)是活的(de)(de)(de)(de)(de)(de)“發電(dian)(dian)(dian)(dian)機(ji)”。它尾部兩側(ce)的(de)(de)(de)(de)(de)(de)肌肉(rou)(rou)，是由(you)有(you)(you)規則地排列著的(de)(de)(de)(de)(de)(de)6000～10000枚肌肉(rou)(rou)薄(bo)片(pian)組(zu)成(cheng)，薄(bo)片(pian)之間有(you)(you)結締組(zu)織相隔，并有(you)(you)許多神經直通中(zhong)樞(shu)神經系(xi)統(tong)。每枚肌肉(rou)(rou)薄(bo)片(pian)像(xiang)一(yi)(yi)個小(xiao)電(dian)(dian)(dian)(dian)池，只能產生(sheng)150毫伏的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓，但(dan)近萬個“小(xiao)電(dian)(dian)(dian)(dian)池”串聯(lian)起來(lai)，就(jiu)可以(yi)產生(sheng)很高的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓。電(dian)(dian)(dian)(dian)鰩(yao)尾部發出的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流，流向(xiang)頭部的(de)(de)(de)(de)(de)(de)感受(shou)器，因(yin)此(ci)在它身(shen)體周(zhou)圍形成(cheng)一(yi)(yi)個弱電(dian)(dian)(dian)(dian)場。電(dian)(dian)(dian)(dian)鰻中(zhong)樞(shu)神經系(xi)統(tong)中(zhong)有(you)(you)專門的(de)(de)(de)(de)(de)(de)細(xi)胞來(lai)監視電(dian)(dian)(dian)(dian)感受(shou)器的(de)(de)(de)(de)(de)(de)活動，并能根據監視分析的(de)(de)(de)(de)(de)(de)結果(guo)指揮電(dian)(dian)(dian)(dian)鰻的(de)(de)(de)(de)(de)(de)行(xing)(xing)為(wei)(wei)(wei)，決定采取(qu)捕食行(xing)(xing)為(wei)(wei)(wei)或避讓行(xing)(xing)為(wei)(wei)(wei)或其它行(xing)(xing)為(wei)(wei)(wei)。有(you)(you)人做(zuo)過這么一(yi)(yi)個實驗：在水池中(zhong)放置兩根垂直的(de)(de)(de)(de)(de)(de)導(dao)線(xian)，放入(ru)電(dian)(dian)(dian)(dian)鰩(yao)，并將水池放在黑暗(an)的(de)(de)(de)(de)(de)(de)環境里(li)，結果(guo)發現(xian)電(dian)(dian)(dian)(dian)鰻總(zong)在導(dao)線(xian)中(zhong)間穿梭，一(yi)(yi)點(dian)兒(er)也不會碰導(dao)線(xian)；當導(dao)線(xian)通電(dian)(dian)(dian)(dian)后(hou)，電(dian)(dian)(dian)(dian)鰩(yao)一(yi)(yi)下子就(jiu)往后(hou)跑(pao)了(le)。這說明電(dian)(dian)(dian)(dian)鰻是靠(kao)“電(dian)(dian)(dian)(dian)感”來(lai)判(pan)斷(duan)周(zhou)圍環境的(de)(de)(de)(de)(de)(de)。
電(dian)(dian)鰩放完體(ti)內(nei)蓄存的電(dian)(dian)能后(hou)，要經過一段(duan)時間的積聚，才能繼續放電(dian)(dian)。
世界(jie)上已知的發電魚(yu)類達數十種呢，其他會放(fang)電的魚(yu)類還(huan)有電鯰(nian)、電鰻(man)等。
吸力超強電(dian)鰩這(zhe)個新品種(zhong)是已知最大的(de)(de)(de)電(dian)鰩家(jia)(jia)族單鰭電(dian)鰩科(ke)的(de)(de)(de)成員(yuan)，它(ta)之所以能進入年度十大發現新物種(zhong)排(pai)名榜(bang)中，是因為它(ta)的(de)(de)(de)屬名非常與(yu)眾(zhong)不同且很(hen)有趣。科(ke)學(xue)家(jia)(jia)拍攝的(de)(de)(de)電(dian)鰩覓食錄像中顯示，這(zhe)種(zhong)魚可(ke)在(zai)水中像吸塵器一樣捕食獵(lie)物，或(huo)許能跟用(yong)(yong)來吸取地毯、家(jia)(jia)具(ju)和(he)其他容易落灰塵的(de)(de)(de)現代(dai)家(jia)(jia)居用(yong)(yong)品表面的(de)(de)(de)雜物的(de)(de)(de)電(dian)動吸塵器相媲美(mei)。因此科(ke)學(xue)家(jia)(jia)按照伊萊(lai)克斯(electrolux)真空吸塵器的(de)(de)(de)名字(zi)給它(ta)命名。
