I-Electric Account - Igama elisungulwe ngokomlando lamaqembu amaqabunga angajwayelekile athinta izisulu ngokukhishwa kukagesi. Namuhla zihlobene noGenes Electrophororus, lapho kunezinhlobo ezintathu zezinhlanzi ezihlala ezindaweni zokugcina zaseNingizimu Melika. Ama-blows anamandla kakhulu abangela i-electrophorus voltai: I-Voltage ingafinyelela kuma-volts angama-860. Ukushaywa kuphazamisa ukuqinisekiswa kwemisipha nokukhubazeka okwesikhashana isisulu, ukuvumela ukuba ukuthathe ngaphandle kokuhlose okunembile futhi okuyinkimbinkimbi okuhlose amanzi emfuleni.
Kwesinye isikhathi izikhundla eziphelele zalezi zinduna ziyazingela futhi zidedelwa zihlelekile, kugcizelela umphumela obulalayo wamanje nokushaya inqwaba yezinhlanzi ezincane. Ukuziphatha okumangazayo okurekhodwe ithimba lakwaDolothists eliholwa nguDavid de Santana (David de Santana) kusuka kuSmithson Museum of Natural History. Balandise ngakho esihlokweni esishicilelwe kumagazini kanye nokuziphendukela kwemvelo.
Eminyakeni embalwa edlule, ngesikhathi sososayensi base-Amazon, ososayensi baseBrazil baqala ukubona ukuthi kwelinye lamachibi amancane endawo, izinduna zikagesi zabuthana ngenani elingaphezu kwekhulu - lokhu kwabhekwa njengokujwayelekile ngokuphelele kwalaba bantu. Ezungeza umhlambi wezinhlanzi ezifuywayo, anciphise umbuthano, angqongqoze ukuhlaselwa okuhlanganisiwe ngamaqembu amancane, aphoqa ngamaqembu amancane, abaphoqa ukuba baphume izisulu eziningi futhi bahlanganyele nabo.
Ukuqashelwa kwavela ngokungajwayelekile kakhulu uma kungenxa yokuthi ukuzingela kweqembu kuyinto evuthayo yezinhlanzi. Ngokusho kukaDe Santana, kusukela ezinkulungwaneni zezinhlobo azikho ngaphezu kweziyisishiyagalolunye zibonisa ukuziphatha okunjalo. Ngakho-ke, ososayensi baseBrazil bacela usizo kozakwabo abaholwa ngochwepheshe abavelele abavela eSmithson Museum futhi bahlela uhambo olusha nolulungiselelwe. Lo msebenzi ukuqinisekisile lokho okwenziwe yibo.
Iningi le-electrophorus voltai usuku luhlala seddiments futhi lushaye phansi ekujuleni kwamanzi anodaka. Kodwa-ke, kusihlwa, acushiwe futhi avunwa ngemihlambi emikhulu, ukubhukuda okubanzi aze azungeze umhlambi ofanele wezinhlanzi ezincane, agxile ekujuleni kobuso. Amaqhinga afanayo asebenzisa imikhomo ye-humpback olwandle, noma kunjalo, ama-erox abe esevela ehlasela "athi" amasheya kagesi ". Emaqenjini abantu abangu-2- 10, bahlelwa ngokuhlanganiswa, abakhubazekile inqwaba yokukhiqiza, wonke umuntu anamathela ngokushesha. Okulandelayo, inqubo iyaphindwa: lapho izitho zikagesi zeqembu lokuqala le-Acne sezikhishwe, kukhona ithuba lokulandelayo.
Sekukonke, abacwaningi babhale amacala angama-72 eqembu elinjalo "ukuzingela ngemivimbo kagesi". Ababhali baphawula ukuthi ukuziphatha okunjalo kusabonakala kuphela ku-electrophorus voltai - futhi kuphela echibini elincane e-Amazon River Iriri. Ngakho-ke, akukaziwa ukuthi kusatshalaliswa kanjani, futhi uma kungenjalo, pho kungani kuvela lapha.
Mhlawumbe inkinga ngokuntuleka kokuphangwa okukhulu ngokwanele kulokhu kudonswa kukagesi: Ukusetshenziswa kukagesi kunhlanzi ngayinye encane - injabulo enkulu kakhulu ye-Acne, ngakho-ke ukuzingela kwamaqembu kukuvumela ukuthi usebenzise izinsiza ezisebenza kahle. UDe Santana nozakwabo sebevele bakhiphe amadokhumenti adingekayo ukuqoqa amakhophi amaningana kulezi zinhlanzi nokuhamba eJalimane, lapho ososayensi behlela khona ukuhlola indlela yabo yokuziphatha kweqembu.
