電鰩科(Torpedinidae)、單鰭電鰩科(Narkidae)、無(wu)鰭電鰩科(Temeridae)魚類的統(tong)稱，以(yi)能(neng)發電傷人而聞名(ming)。見(jian)于世界熱(re)、溫帶水(shui)域(yu)。種類多(duo)，多(duo)棲於(wu)淺水(shui)，但深(shen)海電鰩屬(shu)(Benthobatis)等(deng)可生活於(wu)1,000公(gong)尺(3,300呎)以(yi)下(xia)的深(shen)水(shui)。活動(dong)緩慢，底棲，以(yi)魚類及(ji)無(wu)脊椎動(dong)物為食。如不被(bei)觸及(ji)則對(dui)人無(wu)害，經濟價值(zhi)微不足道。

軟骨魚(yu)綱電(dian)(dian)(dian)鰩目(mu)是板腮(sai)類魚(yu)的一(yi)個目(mu)，此目(mu)的魚(yu)腮(sai)裂(lie)和口都在腹(fu)位，有(you)五個腮(sai)裂(lie)，身(shen)體(ti)平(ping)扁卵圓形，吻不(bu)突(tu)出，臀(tun)鰭(qi)消失(shi)，尾鰭(qi)很小，胸(xiong)鰭(qi)寬(kuan)大，胸(xiong)鰭(qi)前緣(yuan)和體(ti)側相連接。在胸(xiong)鰭(qi)和頭之(zhi)間的身(shen)體(ti)每(mei)側有(you)一(yi)個大的發(fa)電(dian)(dian)(dian)器官，能發(fa)電(dian)(dian)(dian)，以電(dian)(dian)(dian)擊敵人或獵物(wu)，卵胎生，分(fen)布在熱(re)帶和亞熱(re)帶近(jin)海(hai)，半埋在泥沙中(zhong)等待獵物(wu)，一(yi)般(ban)體(ti)形較小，沒有(you)食(shi)用價值。根據(ju)背鰭(qi)的多少，分(fen)為(wei)三科：
電(dian)(dian)(dian)鰩最大的(de)(de)(de)個(ge)(ge)(ge)體(ti)可以達到2米(mi),很(hen)少在(zai)0.3米(mi)以下。背腹扁平,頭(tou)(tou)和胸(xiong)部在(zai)一(yi)(yi)起。尾部呈(cheng)粗棒狀,像團扇。電(dian)(dian)(dian)鰩棲居在(zai)海底,一(yi)(yi)對小(xiao)眼長在(zai)背側(ce)面(mian)前方(fang)的(de)(de)(de)中(zhong)間。在(zai)頭(tou)(tou)胸(xiong)部的(de)(de)(de)腹面(mian)兩側(ce)各有(you)一(yi)(yi)個(ge)(ge)(ge)腎臟形蜂窩狀的(de)(de)(de)發電(dian)(dian)(dian)器(qi)。它們排列成六角柱(zhu)體(ti)，叫“電(dian)(dian)(dian)板(ban)”柱(zhu)。電(dian)(dian)(dian)鰩身上共有(you)2000個(ge)(ge)(ge)電(dian)(dian)(dian)板(ban)柱(zhu)，有(you)200萬塊“電(dian)(dian)(dian)板(ban)”。這些電(dian)(dian)(dian)板(ban)之間充滿膠(jiao)質(zhi)狀的(de)(de)(de)物質(zhi)，可以起絕緣作(zuo)用。每個(ge)(ge)(ge)“電(dian)(dian)(dian)板(ban)”的(de)(de)(de)表面(mian)分布有(you)神(shen)(shen)經(jing)末梢，一(yi)(yi)面(mian)為(wei)負電(dian)(dian)(dian)極(ji)，另(ling)一(yi)(yi)面(mian)則為(wei)正(zheng)電(dian)(dian)(dian)極(ji)。電(dian)(dian)(dian)流的(de)(de)(de)方(fang)向是(shi)從正(zheng)極(ji)流到負極(ji)，也就(jiu)是(shi)從電(dian)(dian)(dian)鰩的(de)(de)(de)背面(mian)流到腹面(mian)。在(zai)神(shen)(shen)經(jing)脈沖(chong)的(de)(de)(de)作(zuo)用下，這兩個(ge)(ge)(ge)放電(dian)(dian)(dian)器(qi)就(jiu)能把(ba)神(shen)(shen)經(jing)能變(bian)成為(wei)電(dian)(dian)(dian)能，放出(chu)電(dian)(dian)(dian)來(lai)。單個(ge)(ge)(ge)“電(dian)(dian)(dian)板(ban)”產(chan)生的(de)(de)(de)電(dian)(dian)(dian)壓(ya)很(hen)微弱，可是(shi)，由于(yu)數量很(hen)多，就(jiu)能發出(chu)很(hen)強的(de)(de)(de)電(dian)(dian)(dian)壓(ya)來(lai)。電(dian)(dian)(dian)鰩的(de)(de)(de)每一(yi)(yi)個(ge)(ge)(ge)電(dian)(dian)(dian)板(ban)，只(zhi)是(shi)肌纖維的(de)(de)(de)變(bian)態。發電(dian)(dian)(dian)器(qi)官是(shi)從某(mou)些鰓肌演變(bian)而來(lai)的(de)(de)(de)。在(zai)演變(bian)發生過程(cheng)中(zhong)解除了腮肌原來(lai)的(de)(de)(de)職務，而承擔了新的(de)(de)(de)作(zuo)用——發電(dian)(dian)(dian)。
自我保護
發(fa)電(dian)(dian)器(qi)最(zui)主(zhu)要的(de)(de)(de)(de)(de)樞紐，是器(qi)官的(de)(de)(de)(de)(de)神(shen)經(jing)部分，電(dian)(dian)鰩能隨意放(fang)電(dian)(dian)，放(fang)電(dian)(dian)時間和強度，它完(wan)全能夠自己掌握(wo)。電(dian)(dian)鰩可(ke)以發(fa)電(dian)(dian),并靠發(fa)出的(de)(de)(de)(de)(de)電(dian)(dian)流(liu)擊(ji)(ji)斃水中的(de)(de)(de)(de)(de)小魚、蝦及其他的(de)(de)(de)(de)(de)小動物,是一種捕食和打(da)擊(ji)(ji)敵害的(de)(de)(de)(de)(de)手段。
世界上(shang)有好多種(zhong)電(dian)(dian)(dian)鰩(yao),其(qi)發電(dian)(dian)(dian)能力各不(bu)相同。非(fei)洲電(dian)(dian)(dian)鰩(yao)一次(ci)發電(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)壓(ya)在220伏(fu)(fu)左右,中等大小(xiao)的(de)(de)電(dian)(dian)(dian)鰩(yao)一次(ci)發電(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)壓(ya)在70～80伏(fu)(fu),像(xiang)較小(xiao)的(de)(de)南美電(dian)(dian)(dian)鰩(yao)一次(ci)只能發出37伏(fu)(fu)電(dian)(dian)(dian)壓(ya)。由于電(dian)(dian)(dian)鰩(yao)會發電(dian)(dian)(dian)，人們(men)叫它做活的(de)(de)發電(dian)(dian)(dian)機、活電(dian)(dian)(dian)池、電(dian)(dian)(dian)魚等。
電鰩(yao)可以放(fang)(fang)出50安培的電流，電壓達60～80伏(fu)，有海(hai)中“活電站”之稱。電鰩(yao)每(mei)秒(miao)鐘(zhong)能(neng)(neng)放(fang)(fang)電50次，但連續放(fang)(fang)電后，電流逐漸減弱，10～15秒(miao)鐘(zhong)后完全消失，休(xiu)息一會后又能(neng)(neng)重新恢復放(fang)(fang)電能(neng)(neng)力。
電(dian)鰩的放(fang)電(dian)特性啟(qi)(qi)發人們(men)發明和創造(zao)了能貯(zhu)存電(dian)的電(dian)池(chi)。人們(men)日常生活中所用的干電(dian)池(chi)，在正負極間的糊狀填充物，就是受電(dian)鰩發電(dian)器里的膠狀物啟(qi)(qi)發而改進的。
早在(zai)(zai)(zai)古希臘和羅馬時代，醫生們常常把(ba)病人放到(dao)電(dian)鰩(yao)(yao)身(shen)上，或者讓病人去(qu)碰一下正(zheng)在(zai)(zai)(zai)池中放電(dian)的(de)(de)電(dian)鰩(yao)(yao)，利(li)用電(dian)鰩(yao)(yao)放電(dian)來治(zhi)療風(feng)濕癥(zheng)和癲狂(kuang)癥(zheng)等病。就(jiu)是到(dao)了今天，在(zai)(zai)(zai)法國和意(yi)大(da)利(li)沿海，還(huan)可能看到(dao)一些患(huan)有(you)風(feng)濕病的(de)(de)老年人，正(zheng)在(zai)(zai)(zai)退(tui)潮后(hou)的(de)(de)海灘上尋找電(dian)鰩(yao)(yao)，當(dang)做自己的(de)(de)“醫生”呢(ni)。
放電原因
1989年，在(zai)(zai)法國科學城(cheng)舉辦了(le)(le)一(yi)(yi)次(ci)饒有(you)趣(qu)味(wei)的(de)(de)“時鐘(zhong)(zhong)”回顧(gu)展覽，一(yi)(yi)座用(yong)帶電(dian)魚(yu)(yu)放(fang)(fang)出的(de)(de)電(dian)來驅動的(de)(de)時鐘(zhong)(zhong)，引起(qi)了(le)(le)人們極大(da)的(de)(de)興趣(qu)。這種帶電(dian)魚(yu)(yu)放(fang)(fang)電(dian)十分(fen)有(you)規律，電(dian)流的(de)(de)方向一(yi)(yi)分(fen)鐘(zhong)(zhong)變換一(yi)(yi)次(ci)，因而(er)被(bei)人稱為“天(tian)然(ran)報(bao)時鐘(zhong)(zhong)”。常見的(de)(de)帶電(dian)魚(yu)(yu)有(you)電(dian)鰻、電(dian)鰩、電(dian)鯰(nian)等。其中(zhong)電(dian)鰩電(dian)力第二強了(le)(le)。 它放(fang)(fang)電(dian)電(dian)壓可(ke)達300～500伏(fu)，足以(yi)把(ba)附近的(de)(de)魚(yu)(yu)電(dian)死(si)，人和牲畜碰上，全身也(ye)會麻痹。據計(ji)算，1萬(wan)條電(dian)鰩的(de)(de)電(dian)能聚集(ji)在(zai)(zai)一(yi)(yi)起(qi)，足夠(gou)使1列(lie)電(dian)力機(ji)車運行幾(ji)分(fen)鐘(zhong)(zhong)。
放電原理
原來，電(dian)(dian)(dian)(dian)(dian)(dian)鰩是活的(de)(de)(de)“發電(dian)(dian)(dian)(dian)(dian)(dian)機”。它尾部兩側的(de)(de)(de)肌肉，是由有(you)規則(ze)地(di)排列(lie)著的(de)(de)(de)6000～10000枚肌肉薄片組(zu)(zu)成(cheng)，薄片之間有(you)結(jie)締(di)組(zu)(zu)織相隔，并有(you)許多神(shen)經(jing)直通(tong)中(zhong)樞(shu)神(shen)經(jing)系(xi)統。每枚肌肉薄片像一個(ge)小電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，只(zhi)能(neng)(neng)產生150毫伏的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓，但(dan)近萬個(ge)“小電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)”串聯起來，就可以產生很高的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓。電(dian)(dian)(dian)(dian)(dian)(dian)鰩尾部發出的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流，流向頭部的(de)(de)(de)感(gan)(gan)受器，因此在(zai)它身(shen)體(ti)周圍(wei)形成(cheng)一個(ge)弱電(dian)(dian)(dian)(dian)(dian)(dian)場。電(dian)(dian)(dian)(dian)(dian)(dian)鰻(man)中(zhong)樞(shu)神(shen)經(jing)系(xi)統中(zhong)有(you)專門的(de)(de)(de)細胞來監視電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)受器的(de)(de)(de)活動，并能(neng)(neng)根據監視分析(xi)的(de)(de)(de)結(jie)果指揮(hui)電(dian)(dian)(dian)(dian)(dian)(dian)鰻(man)的(de)(de)(de)行為，決定采取(qu)捕食行為或避讓行為或其(qi)它行為。有(you)人做過這么一個(ge)實(shi)驗：在(zai)水(shui)池(chi)中(zhong)放(fang)(fang)置兩根垂(chui)直的(de)(de)(de)導(dao)線(xian)，放(fang)(fang)入電(dian)(dian)(dian)(dian)(dian)(dian)鰩，并將水(shui)池(chi)放(fang)(fang)在(zai)黑暗的(de)(de)(de)環境里，結(jie)果發現電(dian)(dian)(dian)(dian)(dian)(dian)鰻(man)總在(zai)導(dao)線(xian)中(zhong)間穿梭，一點兒也不會碰導(dao)線(xian)；當導(dao)線(xian)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)后，電(dian)(dian)(dian)(dian)(dian)(dian)鰩一下(xia)子就往后跑了(le)。這說(shuo)明電(dian)(dian)(dian)(dian)(dian)(dian)鰻(man)是靠“電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)”來判斷(duan)周圍(wei)環境的(de)(de)(de)。
電(dian)鰩放完體內蓄(xu)存(cun)的電(dian)能后(hou)，要經過一段時間的積聚，才能繼(ji)續(xu)放電(dian)。
世界上已知的(de)發電(dian)魚(yu)類達數十種呢，其(qi)他會(hui)放電(dian)的(de)魚(yu)類還有電(dian)鯰、電(dian)鰻等。
吸(xi)(xi)力(li)超強(qiang)電(dian)鰩這(zhe)個新品(pin)種(zhong)是已知最(zui)大的(de)(de)電(dian)鰩家族單(dan)鰭(qi)電(dian)鰩科(ke)的(de)(de)成員，它(ta)之所以能進入年度(du)十大發現新物種(zhong)排名榜中(zhong)，是因為它(ta)的(de)(de)屬(shu)名非常與眾不同且(qie)很有(you)趣。科(ke)學家拍攝(she)的(de)(de)電(dian)鰩覓(mi)食錄像(xiang)中(zhong)顯(xian)示，這(zhe)種(zhong)魚可在(zai)水(shui)中(zhong)像(xiang)吸(xi)(xi)塵(chen)器一樣捕(bu)食獵物，或許能跟用來吸(xi)(xi)取地毯(tan)、家具和(he)其(qi)他容(rong)易落灰塵(chen)的(de)(de)現代(dai)家居用品(pin)表面的(de)(de)雜物的(de)(de)電(dian)動吸(xi)(xi)塵(chen)器相媲美。因此科(ke)學家按(an)照伊萊克斯(electrolux)真空吸(xi)(xi)塵(chen)器的(de)(de)名字(zi)給它(ta)命名。
