Belukha Ingabe umkhomo onamazinyo ongavamile futhi esinye sezilwane ezincelisayo ezinkulu kunazo zonke eMhlabeni. Ingabonakala kalula ngombala wayo ohlukile nokuma komzimba. Imikhomo yokuzalwa eluhlaza okwesibhakabhaka noma mpunga, iba mhlophe ngokuthomba. Inhloko ebabazekayo ibukeka kakhulu njengehlengethwa elinokumomotheka okuphawulekayo nokubukeka okukhaliphile, okubuzayo. Ukungabi khona kwesiphetho se-dorsal kanye nekhanda eligudlukayo kunika isithombe somuntu osongwe.
Umsuka wezinhlobo nencazelo
Isithombe: Belukha
Igama elithi Delphinapterus leucas livela kwelesiGrikhi elithi "delphis" - ihlengethwa. Igama elithi “Apterus” ngokwezwi nezwi lihumusha ngokungabi nangamaphiko, okukhombisa ngokushesha ukungabi bikho kwephiko elibonakalayo lomhlane emkhomeni i-beluga. Igama lezinhlobo "leucas" livela kwele Greek "leucos" - elimhlophe.
Ngohlobo, i-Delphinapterus leucas ingezezingxabano eziphakeme kakhulu. Lesi silwane esincelisayo sasolwandle sohlelo lwama-cetaceans singokomndeni we-narwhal. Okuwukuphela kommeleli wohlobo lweBelukha ngu (Delphinapterus de Lacépède, 1804).

Izincazelo zokuqala zemikhomo ye-beluga zenziwa ngasekupheleni kwekhulu le-18. Umcwaningi uPeter Pallas, ngenkathi eseRussia, wezwa ngalesi silwane esingajwayelekile futhi waqopha nokulandisa kofakazi bokuzibonela. Ngemuva kwalokho, ngesikhathi evakashele eGulf of Ob, isazi semvelo saba nenhlanhla yokuzibonela futhi sichaze ngokuningiliziwe umkhomo omhlophe ngo-1776. Lesi silwane safakwa ezincwadini zemibhalo yezilwane futhi sahlukaniswa ngo-1804.
I-Beluga whale ibhekwa njengokutholwa kwangempela kososayensi bezinto eziphilayo kuwo wonke amazwe futhi isabhekwa njengesilwane esingafundiwe ngokuphelele. Izingxabano ngobunye bezinhlobo zemikhomo emhlophe zavela phakathi nekhulu lama-20. Abanye ososayensi bezinto eziphilayo bazama ukuhlukanisa lo mkhoma onamazinyo ube yizinto eziphilayo, kuyilapho abanye begcizelela ukuthi kube nesilinganiso esisodwa.
Ukucabanga ngemvelaphi yezinhlobo nezimpikiswano mayelana nokwakheka kohlobo lwesilwane kwaqhubeka kwaze kwaba sekuqaleni kwekhulu lama-21. Namuhla, kufinyelelwe esivumelwaneni ngodaba lokuba yilolu hlobo lwale nhlobo. Umkhomo omhlophe uchazwa ngokuthi wuhlobo olulodwa kuphela lwe-beluga whale.
Iqiniso elijabulisayo: Ososayensi bakholelwa ukuthi imikhomo yokuqala yavela ezilwaneni ezincelisayo zasemhlabeni ezabuyela emanzini eminyakeni eyizigidi ezingama-55-60 edlule. Abamele bokuqala bomndeni we-narwhal bavele kamuva - eminyakeni eyizigidi eziyi-9-10 edlule engxenyeni esenyakatho-mpumalanga yePacific Ocean.
Ukubukeka nezici
Isithombe: Isilwane esincelisayo saseBeluga
Umkhomo i-beluga ubizwa nge-dolphin yasolwandle. Ikhanda elincane elihle elinenqubo egqamile, impumulo enwetshiwe nomlomo "omomothekayo" ngokungangabazeki ukhaphela isihlobo samahlengethwa emkhomeni. Inhloko ehambayo yomkhomo i-beluga yehlukanisa nezinye izihlobo ngokulandelana. Lesi sici sigcinwe ezinhlotsheni ngenxa yama-vertebrae, angazange afane, njengabanye abameleli be-cetaceans.
Ngenxa yalesi sici, umkhomo onamazinyo unamahlombe aphume ngaphandle, isifuba esibanzi nomzimba onamathela emsileni. Isikhumba siyashelela, siyacwebezela, sinwebeka. Ubude bomzimba womkhomo omdala bufinyelela kumamitha ayisithupha. Umkhomo omhlophe unamaphiko angaphambili amancane ngokungalingani uma uqhathanisa nomzimba. Ubude bazo bungu-1% wobude bomzimba obuphelele - amasentimitha angama-60, ububanzi bawo bungamasentimitha angama-30. Amaphiko amancane anxeshezelwa ububanzi bomsila. Ububanzi bayo buyimitha, futhi kwesinye isikhathi bube ngaphezulu.
Izici zokwakheka nezomzimba womkhomo zivumelaniswa nempilo yase-Arctic. Isisindo sowesilisa osekhulile singahluka kusuka ku-1600 kuya ku-2000 kilogram. Amaphesenti amakhulu esisindo angamafutha angaphansi kwesikhumba. Emikhomeni emhlophe, ingafinyelela uhhafu wesisindo somzimba, kanti kweminye imikhomo ingama-20% kuphela.
Ukuzwa kuthuthukiswa kahle ezilwaneni. Izici ezihlukile ze-echolocation zivumela i-beluga whale ukuthi ithole izimbobo zokuphefumula ngaphansi kwesembozo solwandle. Umhlathi omuhle womkhomo omhlophe uqukethe amazinyo angama-30 kuye kwangama-40. Zinesimo esimise okwekhanda, esenzeka ngenxa yokushayisana kwamazinyo komunye nomunye. Lokhu kungenxa yokulunywa kwe-wlique oblique. Imihlathi ephume kancane namazinyo atshekile avumela umkhomo we-beluga ukuba ulume isisulu sawo.
Le mikhomo ibhukuda kancane. Ijubane lisuka ku-3 kuye ku-9 km ngehora. Kodwa-ke, umkhoma i-beluga ungafinyelela ngesivinini esiphezulu samakhilomitha angama-22 ngehora bese uwubamba imizuzu eyi-15. Banokuhamba okuhle. Bangakwazi ukuqhubekela phambili nangemuva.
Bangena emanzini angajulile lapho amanzi emboza umzimba. Imvamisa ama-belugas awacwili kakhulu, cishe amamitha angama-20. Kodwa-ke, futhi bayakwazi ukudilika ekujuleni okwedlulele. Ngaphansi kwezimo zokuhlolwa, umkhoma we-beluga oqeqeshiwe wenza ama-dives amaningana waba ngamamitha angama-400. Omunye umkhoma wacwila kumamitha angama-647. I-dive ejwayelekile ihlala ngaphansi kwemizuzu eyi-10, kepha ingahlala ngaphansi kwamanzi imizuzu engaphezu kwengu-15.
Uhlala kuphi uBeluga?
Isithombe: whale beluga
Umkhomo onamazinyo uhlala emanzini asenyakatho:
- Ulwandle;
- Izilwandle;
- Amabhayi;
- AmaFjords.
Ingena emanzini angajulile olwandle lwase-Arctic, aqhubeka nokufudunyezwa yilanga. Kunezimo lapho imikhomo ye-beluga ivela emlonyeni wemifula. Lokhu kwenzeka ehlobo. Imikhomo iyondla, ixhumane futhi izalane. Ukushisa kwamanzi ngalesi sikhathi kusuka ku-8 kuye ku-10 degrees Celsius.
Imikhomo yaseBeluga itholakala olwandle oluse-arctic nolungaphansi komhlaba eCanada, eGreenland, eNorway, eRussia nase-Alaska. Kunabantu abahlukene eGulf of St. Lawrence naseLwandle lwase-Okhotsk empumalanga yeRussia. Kuwo wonke amabanga abo, kunabantu abahlukahlukene abahlala ezindaweni ezihlukene zolwandle olusenyakatho.
Imikhomo yaseBeluga ihlala eWhite naseKara Seas. Bavame ukuvakashela izindawo ezincane ezingasogwini, kepha bangangena emanzini amamitha angamakhulu ambalwa befuna ukudla. Umkhomo wamazinyo utholakala ngasogwini lwaseRussia, eCanada, eGreenland nase-Alaska. Kubonakala empumalanga Hudson Bay, Ungava Bay, naseSt. Lawrence River.
Umkhomo i-beluga uchitha izinyanga zasebusika ngasogwini lwaseGreenland, futhi lapho kuqala ukushisa, uhamba ngomkhumbi uye ogwini olusentshonalanga lweDavis Strait. Kunobufakazi bokuthi imikhomo yahlangatshezwa ngasogwini lwaseScotland e-Edinburgh Strait. Kuze kube maphakathi nekhulu leminyaka elidlule, umkhoma i-beluga ungene emifuleni emikhulu i-Ob, Yenisei, Lena, Amur, kwesinye isikhathi inyuka ngomfula amakhulu ngamakhilomitha.
Imikhoma yaseBeluga ivame kakhulu emanzini asogwini oLwandle i-Arctic, kepha ayatholakala nasemanzini angaphansi komhlaba. Imikhomo ifudukela eningizimu ngemihlambi emikhulu lapho amanzi eqala ukuba yiqhwa.
Udla ini umkhoma i-beluga?
Isithombe: Beluga animal
Imikhoma yaseBeluga idla ngokuhlukile. Zidla izinhlobo ezingaba yikhulu, ezitholakala kakhulu olwandle. Ukudla komkhomo i-beluga kuqukethe kuphela ukudla kwasolwandle.
Izinsalela zama-crustaceans kanye nezingenamgogodla zitholakala esiswini semikhomo ye-beluga:
- Ama-octopus;
- I-Cuttlefish;
- Izinkalankala;
- AmaMolluscs;
- Izikelemu.
Umkhomo onamazinyo uthanda inhlanzi.
Ukudla kufaka:
- UCapelin;
- Ikhodi;
- I-herring;
- Shungela;
- I-Flounder.
Ngokuya ngemininingwane etholwe ngokugcina ama-belugas ekuthunjweni, badla amakhilogremu ayi-18 kuye kwangama-27 okudla ngosuku. Lokhu kungu-2.5-3% wesisindo sabo somzimba esiphelele.
Imikhoma yaseBeluga ivame ukuzingela emanzini angajulile. Intamo eguquguqukayo imvumela ukuba enze izindlela ezinzima ngenkathi ezingela. Ukubheka kukhombisa ukuthi umkhoma i-beluga ungadonsela amanzi emlonyeni wawo uwukhiphele ngaphandle kwengcindezi enamandla, njengoba kwenza ama-walrus. Indiza enamandla igeza phansi. Ukumiswa esihlabathini nokudla kukhuphukela phezulu. Ngakho-ke, umkhomo ungaphakamisa inyamazane yolwandle.
Umkhoma waseBeluga uzingela izikole zezinhlanzi. Sebebuthene eqenjini lemikhomo emi-5 noma ngaphezulu, ama-belugas ahambisa izinhlanzi ezikoleni emanzini angajulile, bese ehlasela. Umkhomo awukwazi ukuhlafuna ukudla. Uyigwinya yonke. Amazinyo aklanyelwe ukubamba ngokuphepha noma ukukhipha inyamazane ngenkathi uzingela.
Esiswini semikhomo ye-beluga, izazi zezilwane ziphinde zathola izingcezu zezinkuni, isihlabathi, amatshe kanye nephepha. Kungenzeka ukuthi, lezi zinto zingena emzimbeni wemikhomo ngenkathi zizingela emanzini angajulile. Imikhomo ayikwazi ukugwinya ukudla kuphelele. Izinsiza zabo zokugwinya azivumelaniswanga nalokhu futhi bangavele baminyanise. Ngakho-ke, imikhomo i-beluga ibamba izinhlanzi ezincane, noma inciphise bese iyidwengula.
Izici zobuntu nendlela yokuphila
Isithombe: Belukha
I-Belugas yizilwane ezifuywayo. Bahlangana ngamaqembu abantu abangamakhulu amaningana. Kunezimo lapho ikoloni le-belugas lifinyelela izilwane ezincelisayo ezingaphezu kwenkulungwane. Imikhoma yaseBeluga idinga umoya. Imikhomo ichitha cishe amaphesenti ayishumi esikhathi sayo ebusweni.
Umkhomo unamakhono athuthukile okuxhumana. Imikhomo yaseBeluga ixhumana ngobubanzi obuphezulu futhi isebenzisa i-echolocation. Imisindo ekhiqizwayo inokhahlo futhi inomsindo omkhulu. Zifana nokukhala kwezinyoni. Ngenxa yalokhu imikhomo ye-beluga yabizwa ngokuthi "ama-canaries olwandle". Amazwi abo azwakala njengokukhala, ukushaya ikhwela nokumemeza. Umkhomo onamazinyo ubhekwa njengomunye wemisindo ephezulu kakhulu ngokohlelo lwayo lwezinto eziphilayo. Usebenzisa amazwi ngenkathi edlala, ekhwelana futhi exhumana.
Imikhomo yaseBeluga nayo isebenzisa ulimi lomzimba ukuxhumana nokuxhumana. Banikeza amasiginali, bagedle amazinyo abo, baphikelele ngokubhukuda bezungeze izihlobo zabo, ngazo zonke izindlela bezidonsela ukunaka kubo noma entweni ebathandayo.
Izazi zezinto eziphilayo zifakazele ukuthi imikhomo i-beluga isebenzisa ukuxhumana lapho ikhulisa inzalo yayo. Ziyazinakekela, zidlise futhi zivikele amaphuphu azo. Ukuze kuvikelwe inzalo yazo, zingena emilonyeni yemifula emikhulu, lapho zihlala khona kuze kube amasonto ambalwa. Ngalesi sikhathi, bayancibilika futhi bakhulise amaphuphu abo.
Imikhomo emhlophe yizilwane ezinelukuluku kakhulu ezinengqondo ephilayo futhi ezisheshayo. Ngingena ekuxhumaneni nabantu. Bahamba nemikhumbi, kwesinye isikhathi abayikhokhela ngempilo yabo.
Isakhiwo senhlalo nokuzala
Isithombe: I-Beluga whale cub
Ukukhwelana kwenzeka phakathi kukaFebhuwari noMeyi. Abesilisa baheha ukunakwa kwabesifazane ngokudlala ngothando, ukugijima, ukudlala nokudilika. Ngasikhathi sinye, benza imisindo ephezulu, bachofoze futhi bashaye ikhwela. Emzabalazweni wabesifazane, abesilisa bakhombisa amandla abo nokuphakama kwezimbangi zabo. Abesilisa basebenzisa ukushaywa kwemisila emanzini, ukunikina ikhanda, imisindo esabisayo enzima, nokushukuma komzimba. Basika umphikisi ngokuthambeka okubukhali komzimba, bavimbe umgwaqo futhi bakhombise ngazo zonke izindlela ukuthi indawo ivaliwe.
Isinqumo sokushada senziwa ngowesifazane. Ukuphululwa kwemikhomo emhlophe kungumbono omuhle. Lezi zithandani ziyadlala, zibhukuda ngokuvumelanayo futhi zithinte izidumbu. Inzalo ivela phakathi kukaMashi noSepthemba. Ukukhulelwa kuthatha izinsuku ezingama-400-420. Izazi ze-Zoologists zinesiqiniseko sokuthi imikhomo emhlophe yabesifazane iyakwazi ukunciphisa ukubeletha nokuzalwa kwamathole. Lokhu kucabanga kwenziwa ngesisekelo sokuthi ukubeletha eqenjini kwenzeka cishe ngesikhathi esifanayo. Njengoba inqubo yokukhulelwa kunzima ukuvumelanisa, kwavela umbono wokuvinjelwa kombungu.
Amathole omkhomo amhlophe asanda kuzalwa anesisindo esingama-80 kilograms. Umbala wezingane uluhlaza okwesibhakabhaka noma ompunga. Amathole ahlala nonina okungenani iminyaka emibili. Sonke lesi sikhathi baphakelwa ubisi. Ukuncelisa ubisi ngesikhathi somkhomo kuthatha iminyaka engu-1.5 kuye kwengu-2. Izingane ezisanda kuzalwa ziphakathi kwabesifazane ababili: umama nomzanyana osemusha. Ithole liyanakekelwa, livikelwe futhi likhuliswe ukuze liphefumule umoya.
Imikhomo ifinyelela ekuvuthweni ngokobulili ngeminyaka engu-4-7. Isikhathi sabo sokuphila esiphezulu yiminyaka engama-50. Kukholakala ukuthi abesifazane bahlala ngokwesilinganiso kuze kube yiminyaka engama-32, abesilisa kuze kube ngama-40.
Izitha zemvelo zama-belugas
Isithombe: Imikhomo yaseBeluga olwandle
Ngokwemvelo, imikhomo ye-beluga inezitha eziningi. Njengomthetho, lezi yizilwane ezinkulu ezidla ezinye ngaphansi kwamanzi nasogwini. Uhlobo lwesilwane esidla ezinye, ubukhulu nenombolo kuya ngendawo yokuhlala yomkhomo i-beluga. Phakathi kwazo kukhona imikhomo ebulalayo, amabhere asezindaweni ezibandayo noshaka baseGreenland.
I-Belugas isisulu esilula samabhere we-polar. Umkhomo omhlophe usondela eduze kweqhwa lapho kutholakala khona amabhere okuzingela. Kwesinye isikhathi amabhere eza eqhweni elifudukayo ngokukhethekile ukuzingela, futhi kwesinye isikhathi ahlala kuwo izinsuku ezimbalwa. Ama-polar bear azingela imikhomo ye-beluga futhi ahlasele esebenzisa uzipho namazinyo.
Iqiniso elithakazelisayo: I-beluga whale inezinketho eziningana zokuzivikela - ukufihla, ikhono lokucasha eqhweni nangemuva kwesizwe esikhudlwana esikwaziyo ukuxosha ukuhlaselwa ngumzingeli.
I-Orcas inendlela ehlukile yokuzingela. Lapho umhlambi wemikhomo emhlophe uqala ukufuduka, umkhoma obulalayo ujoyina iqembu futhi alihambise kakhulu, ahlasele futhi ondle njalo. IBelugas ivame ukuzwa imikhomo ebulalayo, ngakho-ke lokhu kwenza kube nzima ukubahlasela. Ngenxa yokuhamba okuphansi kwemikhomo ebulalayo eqhweni, ama-belugas akwazi ukuphunyuka kulabo ababasukelayo.
Oshaka baseGreenland bajaha isikole futhi bahlasela hhayi kuphela ngesikhathi sokufuduka, kepha nasezindaweni abahlala kuzo. Kodwa-ke, imikhomo emhlophe iyakwazi ukumelana ngokuhlanganyela. Imvamisa, izilwane zibhajwe eqhweni lase-Arctic bese ziyafa, zibe yizisulu zamabhere asezindaweni eziphakeme, imikhomo ebulalayo kanye nabantu bendawo.
Abantu bahlala bengusongo olukhulu nosongo ekusindeni kwezinhlobo. Ukuzingela ngezinga lezimboni lesikhumba somkhomo namafutha kunciphise kakhulu inani lezilwane. Izingozi ezinkulu zale mikhomo imfucumfucu enobuthi neyezimboni, udoti, nokushintsha kwesimo sezulu nezemvelo ezindaweni zazo zokuzalela nezindawo ezihlala kuzo.
Ososayensi baphawula ukuthi ukungcola komsindo kuthinta ama-belugas. Ukukhula okubukhali nokuthuthuka kwemikhumbi, ukwanda kokugeleza kwezivakashi zasendle kuphazamisa ukuzala okujwayelekile futhi kuholele ekwehleni kwenani lamathole, futhi ngenxa yalokho, ukwehliswa komhlambi.
Inani labantu kanye nesimo sezinhlobo
Isithombe: Animal beluga
Ukulinganiswa kobuningi bama-belugas kuyahlukahluka kakhulu. Umehluko ezinombolweni ungamashumi ezinkulungwane. Leli iphutha elikhulu kakhulu ngezinhlobo ezingavamile ezinjalo.
Isibalo sabantu emhlabeni njengamanje sisuka ezilwaneni eziyi-150,000 kuya kwezingu-180,000. Izindawo ezingama-whale ezinamazinyo ezingama-30 sezihlonziwe - eziyi-12 zitholakala eRussian Federation. Iqembu elikhulu kunawo wonke lemikhomo - elingaphezu kuka-46% - lihlala njalo lisogwini lwaseRussia.
Izindawo zabantu abaningi:
- IBristol Bay;
- ULwandle iBering Eastern;
- ULwandle lwaseChukchi;
- ULwandle iBeaufort;
- Umhlaba OseNyakatho;
- ENtshonalanga Greenland;

- Iziqhingi zaseShantar.
Izazi zaseCanada ichthyologists zinama-belugas angama-70,000 kuya ku-90,000 esifundeni sawo. Inani labantu basentshonalanga yeHudson Bay libhekwa njengelikhulu kunawo wonke emanzini aseCanada - cishe abantu abangama-24,000. Imikhomo yaseBeluga ehlala kule ngxenye yetheku ibhekwa njengemelana nezinto zangaphandle, yize kunendawo enolaka nokungenelela komuntu empilweni yomkhomo onamazinyo.
Abantu abafudukayo babalwa ngasikhathi sinye ngabamele amazwe ahlukene - iDenmark, iNorway, iRussia, iCanada neGreat Britain. Inombolo yabo ekuqaleni ihluke kakhulu kunaleyo eqedwayo. Lezi zibalo zikhombisa ukulahleka kwamaqembu ekuhlaselweni yizidlakela nemisebenzi yabantu.
Iqembu lezilwane elikhulu kakhulu lihlala ema-zoo, ama-aquariums, ama-aquariums kazwelonke kanye namahlengethwa. Ososayensi badidekile ngokuthi bangaki abantu abangase baboshwe. Ngokokunye ukulinganisela, kungaba kusuka ezilwaneni eziyikhulu noma ngaphezulu kuphela endaweni yaseRussia, futhi cishe ngabantu abangama-250 bakwamanye amazwe omhlaba.
Ukuvikelwa kwama-belugas
Isithombe: IBelukha Red Book
Umkhomo onamazinyo omhlophe ubhalwe kuRed Data Book njengezilwane ezisengozini yokuqothulwa. Uhlu lwezinsongo lubandakanya ukudoba kwezimboni, izinto zangaphandle nodoti wabantu. Abantu bomdabu base-Arctic e-Alaska, eCanada, eGreenland naseRussia bazingela imikhomo ye-beluga. Inani lezilwane ezibulewe cishe liyi-1000 ngonyaka. E-Alaska, kwabulawa abantu abangu-300 kuya ku-400, eCanada kusukela kwabangu-300 kuya ku-400. Kuze kube unyaka ka-2008, i-International Union for Conservation of Nature (IUCN) yahlukanisa umkhomo i-beluga "njengobuthakathaka". Ngo-2008, i-IUCN yayibeka “njengengcuphe eseduze” ngenxa yokwehla ubuningi kwezinye izingxenye zebanga.
Imikhomo yaseBeluga, njengezinye izinhlobo eziningi zase-Arctic, ibhekene noshintsho lwendawo yokuhlala ngenxa yokushintsha kwesimo sezulu kanye nokuncibilika kweqhwa lase-Arctic. Akukacaci ngokuphelele ukuthi kungani imikhomo i-beluga isebenzisa iqhwa, kodwa kucatshangwa ukuthi lena indawo yokukhosela emikhomeni ebulalayo. Izinguquko ebunzimeni beqhwa lase-Arctic zidale ukulahleka okukhulu phakathi kwabantu. Ukushintsha kwesimo sezulu kungazelelwe kungabamba imifantu yeqhwa esetshenziswa imikhomo ukuthola umoya-mpilo, ekugcineni ibulale imikhomo ngokuminyana.
ICongress yaseMelika yaphasisa Umthetho Wokuvikela Izitho Zasemanzini ezivimbela ukulandela nokuzingela zonke izilwane ezincelisayo zasolwandle emanzini asogwini lwase-US. Umthetho uchitshiyelwe kaningana ukuvumela abantu bomdabu ukuba bazingele ukudla, babambe inani elilinganiselwe labantu okwesikhashana ocwaningweni, kwezemfundo nasekubonisweni komphakathi. Umkhomo wezentengiselwano ubeke imikhomo engcupheni yokuqothulwa ezindaweni ezifana neCook Bay, Ungava Bay, iSt. Lawrence River nentshonalanga yeGreenland. Ukuqhutshwa komkhumbi wendabuko okuqhubekayo kungasho ukuthi abanye abantu bazoqhubeka nokuncipha
Belukha - isilwane esiyingqayizivele esedlule uchungechunge oluyinkimbinkimbi lokuziphendukela kwemvelo. Ososayensi bakwazile ukuthola ukuthi okhokho bomkhomo omhlophe wesimanjemanje bake bahlala olwandle olufudumele, nangaphambi kwalokho ebusweni bomhlaba. Leli qiniso lifakazelwa yimivubukulo etholakala enyakatho yeCalifornia, kanye namathambo esilwane sangaphambi komlando esatholakala eVermont, e-USA. Izinsalela ziphumule ekujuleni kwamamitha ama-3 ngaphansi komhlaba futhi kude nolwandle oluseduze ebangeni lama-250 km. Ukuhlaziywa kwe-DNA kunikeze ukufana nekhodi lomkhomo wesimanje we-beluga. Lokhu kufakazela ukuthi okhokho bakhe balushiya ulwandle, base bebuyela endaweni ehlala emanzini.
