'Electrophorus voltai,' one of the two newly discovered electric eel species. (CNN)A newly-identified eel living in the Amazon basin can deliver record-breaking electric jolts, according to a study published Tuesday. 星期二在亞馬遜發現了新的電鰻物種 Researchers at Smithsonian's National Museum of Natural History have identified two new species of electric eel in the Amazon rainforest, tripling the known number of electric eel species. 史密森尼國家自然歷史博物館的研究人員在亞馬遜熱帶雨林中發現了兩種新的電鰻,使已 知數量的電鰻物種增加了兩倍。 One of the new species -- Electrophorus voltai -- can discharge up to 860 volts of electricity, significantly more than the 650 volts generated by the known electric eel species, Electrophorus electricus, the study published in journal Nature Communications found. 發表在Nature Communications雜誌上的研究發現,其中一種新物種 - Electrophorus voltai - 可以釋放高達860伏的電力,遠遠超過已知電鰻物種Electrophorus electricus 產生的650伏電壓。 These electric eels -- which are actually a type of fish with an eel-like appearance -- can grow to up to eight feet (2.4 meters) and highlight how much is yet to be discovered in the Amazon rainforest, study leader David de Santana, a research associate at Smithsonian's National Museum of Natural History, said in a press release. 這些電鰻 - 實際上是一種具有鰻魚般外觀的魚類 - 可以長到8英尺(2.4公尺)。 "They're really conspicuous," de Santana said. "If you can discover a new eight-foot-long fish after 250 years of scientific exploration, can you imagine what remains to be discovered in that region?" The long-recognized electric eel species, 'Electrophorus electricus.' What are electric eels? 什麼是電鰻? For 250 years, scientists have known that electric eels live in the Amazon basin. They just haven't known how many species were lurking there. 250年來,科學家們已經知道電鰻生活在亞馬遜河流域。他們只是不知道有多少物種潛伏 在那裡。 Scientists long thought the electric eels found in swamps, streams, creeks and rivers across South America were all the same species. The new study shows that the eels actually belong to three different species. 科學家們一直認為,在南美洲的沼澤,溪流,小溪和河流中發現的電鰻都屬於同一物種。 新的研究表明,鰻魚實際上屬於三種不同的物種。 All three species look pretty much the same externally and use their electricity to navigate, communicate, hunt and for self-defense. But when scientists analyzed 107 samples, they found that the three species had different genetic material, unique skull shapes, and different levels of voltage. 這三種物種在外部看起來幾乎相同,並使用它們的電力來導航,交流,捕獵和自衛。但是 當科學家分析了107個樣本時,他們發現這3個物種具有不同的遺傳物質,獨特的顱骨形狀 和不同的電壓水平。 Based on their research, de Santana and his team believe that the three species began to evolve from their common ancestor about 7.1 million years ago. 根據他們的研究,de Santana和他的團隊認為這三個物種在大約710萬年前開始從它們的 共同祖先進化而來。 See electric eels' leaping shock attack See electric eels' leaping shock attack 01:05 The eels' voltage may have been influenced by the conductivity of the waters they lived in, the research found. Electrophorus voltai, for instance, lived in the clear waters of the highlands which did not conduct electricity well. According to de Santana, the species' stronger voltage may be an adaption to the poor conductivity of the water. There are about 250 species of fish that are able to generate electricity, but electric eels are the only ones that use electricity to hunt and for self-defense. 大約有250種魚能夠發電,但電鰻是唯一使用電力進行捕獵和自衛的魚類。 In 1799, scientists used electric eels as the inspiration behind the first battery design, and have also inspired ideas about how to improve technology and treat disease. 1799年,科學家們將電鰻用作第一次電池設計的靈感,並激發了關於如何改進技術和治療 疾病的想法。 The newly discovered electric eel species could have evolved unique systems to produce electricity -- perhaps a different system than the first discovered species -- which could lead to more discoveries, de Santana said. "It could really have different enzymes, different compounds that could be used in medicine or could inspire new technology," he said. de Santana說,新發現的電鰻物種可能已經進化出獨特的系統來發電 - 可能是與第一個 發現的物種不同的系統 - 這可能會帶來更多的發現。 5.完整新聞連結 (或短網址): https://is.gd/3pklSW 6.備註: 雷師皓翁,爾等仙卿,儲勳夙世,累行昨生,故得玉府登庸,瓊宮簡錄。今玆勳行,視夙 昨多,爾其悉力,雷司委心火部。日復日,歲復歲,勳崇行著,性霽神融,克證高真,即 階妙道。惟是雷部鬼神,晝勞夕役,動有捶楚,大則考戮屑雲雕雪,無有已時,檄龍命鴉 ,此息彼作,彼所因故爾其耳焉。 -- 七魄興輪無上伊甸瑜珈雖然是以看來較為平和的方式以蟬蛻和生乳取代血肉等腥穢之物 作為密義源起供養;然而聚歛於上的是冥界的深冤與大樂奔瀉的淨慈,行者於閉關修持 之時若生起退失動搖之心,則神識旋即離散且肉身消殞;即便如此還是願意受灌頂嗎? https://imgur.com/cEVD0kE ---妖道七祖《攝一切魔根本瑜珈論/誓命問品第一》---
