Umkhomo i-humpback noma njengoba lesi silwane sibizwa nangothando, iminke ehlomile ende iyisilwane esincelisayo esikhulu sasemanzini esihlala olwandle nasolwandle emhlabeni jikelele. Umkhomo obizwa ngokuthi i-humpback whale ubhekwa njengomunye wemikhomo ehamba phambili kakhulu eyenza imibukiso yangempela, igxume iphume kukholamu lamanzi bese izwakala kakhulu emanzini. Ngemidlalo yabo ye-acrobatic, imikhomo ithole idumela njengemikhomo emnandi.
Umsuka wezinhlobo nencazelo
Isithombe: Umkhomo i-Humpback
I-Megaptera novaeangliae Umkhomo noma i-humpback whale isilwane esincelisayo sasemanzini esikhulu kakhulu somndeni womkhomo onemigqa, okungaphansi kwemikhomo ye-baleen. Uhlobo lwe-Humpback. Imikhomo yizilwane ezincelisayo, futhi izidlo zasendulo ezingadliwayo-mesonychia zibhekwa njengokhokho bazo. Izilwane zifana ngandlela thile nezimpisi ezinezinselo nezinzipho ezibukhali kuzo. Ngakho-ke izihlobo eziseduze zemikhomo emhlabeni wanamuhla zingabhekwa njengezingezona izinhlanzi, kepha kunalokho izimvubu.
Okufana kakhulu nemikhomo yanamuhla emhlabeni wasendulo yizilwane ezincelisayo zomndeni wakwaProtocetid, ezazihola impilo yama-amphibiotic, kepha zazivele zifana ngokwengeziwe nemikhomo yanamuhla. Ukuvuleka kwamakhala kwalezi zilwane kwenyuselwa phezulu, futhi lezi zilwane zase zivele zinomsila ocishe ube ufishi.
Ividiyo: Umkhomo We-Humpback
Isigaba esilandelayo ekuguqukeni kwemikhomo kwakungu-basilosaurs - lezi zidalwa zaziphila eminyakeni engaba yizigidi ezingama-38 edlule. Zazicishe zilingane nemikhomo yesimanje futhi zazinonqenqema lwamafutha olungaphambili olwalunomthwalo wokuthwebula. Ukuwohloka kwamaphethelo kwaphawulwa kulezi zilwane ngenxa yokushintshela kwazo cishe ngokuphelele kokuphila emanzini. Izitho zisakhula kahle, kepha zincane kakhulu futhi azikwazi ukusetshenziselwa ukunyakaza.
Isigaba esilandelayo ekuziphendukeleni kwama-cetaceans kwakuyimikhomo enamazinyo, eyayihlala emzimbeni wamanzi weplanethi yethu kusukela e-Oligocene Ephakathi kuya maphakathi neMiocene. Cishe eminyakeni eyizigidi ezingama-34-14 edlule, lezi zidalwa zazisebenzisa i-echolocation, zabhukuda kahle emanzini futhi zalahlekelwa ukuxhumana nomhlaba. Izinhlobo zasendulo zemikhomo yama-humpback, iMegaptera miocaena, yayihlala emhlabeni wethu ngasekupheleni kweMiocene.
Izinsalela zalezi zilwane ziyaziwa ePleistocene naseLate Pliocene. UGorbach wachazwa okokuqala nguMatrin Jacques Brisson njengo "baleine de la Nouvelle Angleterre" okusho ukuthi "Umkhomo waseNew England" ngo-1756 encwadini yakhe ethi "The Animal Kingdom". Kamuva uGeorg Barovski waqamba kabusha lesi silwane, ehumusha igama laso esiLatin Baleana novaeangliae.
Isazi se-ichthyologist saseFrance uBernard Germain Hélien de la Ville, u-Count Laceped ushintshe ukuhlukaniswa kanye negama lalezi zinhlobo zemikhomo. Ubuye wachaza enye yezinhlobo zasendulo zemikhomo yasendulo, iMegaptera miocaena, eyayiphila ngasekupheleni kweMiocene.
Ukubukeka nezici
Isithombe: Ubukeka kanjani umkhomo i-humpback
I-minke ehlomile ende ingenye yezidalwa ezinkulu kakhulu emhlabeni wethu. Isisindo somuntu omdala cishe singamathani angama-30. Ubude bomzimba bungamamitha ayi-15 kwabesifazane no-12.5-13 kwabesilisa. Kodwa-ke, kunabantu abakhulu ikakhulukazi ubude babo obufinyelela kumamitha ayi-19 futhi bunesisindo esifinyelela kumathani angama-50. Ukwehliswa ngokocansi kuvuna abesifazane. Ngaphandle, abesifazane bahluka kwabesilisa kuphela ngosayizi nangesakhiwo sendawo eyehlisiwe. Umzimba womkhomo uminyene futhi mfushane. Umzimba unwetshwe ngaphambili, umzimba ujiyekile ngemuva futhi ucindezelwe kancane ezinhlangothini.
Ikhanda likhulu futhi liphela ngempumulo eyindilinga. Umhlathi ongezansi ukhule kahle, uqinile futhi uya phambili ngandlela thile. Ukhakhayi lubanzi. Amehlo mancane. Amakhala akulezi zinhlobo atholakala phezulu kwekhanda futhi enza ukuqhuma. Ekhanda, kusukela ku-blowhole kuya empumulweni, kunemigqa emi-4 yeziqu zesikhumba ezifana nezinsumpa.
Emgqeni ophakathi kuneziqu eziyi-6-8, ezinhlangothini ezisuka ku-6 kuye ku-15. Phambi komhlathi ophansi kukhona ukukhula okuncane kakhulu ngobubanzi obufinyelela kumasentimitha angama-32. Konke ukukhula kuyizintambo zezinwele ezishintshiwe, kusuka ngakunye, kusuka kokukhulayo, kukhula izinwele. Usayizi nendawo yeziqu, kanye nombala wemikhomo, kukodwa. Umkhomo unesisu esikhulu esixegayo.
Isisu sinezimphetho zomphimbo omude osuka esilevini uye enkabeni. Ngesikhathi sokudla, le mifula ikhula kakhulu, ngenxa yokuthi umkhomo ungagwinya umthamo omkhulu wamanzi. Kukhona amafolda angaba ngu-20 esewonke, amafolda ombala omhlophe.
Iqiniso elithandekayo: Umkhomo we-humpback unongqimba oluminyene kakhulu lwamafutha angaphansi, avumela isilwane ukuthi sihlale ngaphandle kokudla isikhathi eside futhi sihlale emanzini abandayo.
Amaphiko asesifubeni made kakhulu; ubude bawo bulingana no-30% wobude bomzimba womkhomo. Ngenxa yamaphiko amade kangaka, umkhomo uyakwazi ukubhukuda kahle bese ugxumela phezulu ngaphezu kwamanzi. I-fin etholakala ngemuva incane, ingamasentimitha angaba ngu-32 kuphela.Umngcele ongemuva we-fin uvame ukugoba ngesikela. Umngcele wangaphakathi we-fin awujulile.
Umsila unomphetho omkhulu futhi omkhulu onqenqemeni olucijile. Imikhomo yama-humpback ingaba nemibala ehlukahlukene. Ingemuva nezinhlangothi zomkhomo kuvame ukuba mnyama noma mpunga ngombala. Kunemisele emhlophe esifubeni nasezinhlangothini. Amaphiko atholakala ngaphezulu kwesifuba amnyama noma anemishwe, imvamisa ilula noma imhlophe ngaphansi. Umsila umnyama ngenhla, kusuka ngezansi ungakhanya noma ubonakale.
Kunama-vertebrae ayi-7 entanyeni. Izitho zangaphakathi zivikela amathambo angama-14 we-thoracic, i-10 lumbar vertebrae ne-21 caudal vertebrae. Umkhomo i-humpback ukhipha umthombo omkhulu omise okwe-v, ukuphakama komthombo kungafinyelela kumamitha amathathu.
Uhlala kuphi umkhoma?
Isithombe: Umkhomo i-Humpback eDominican Republic
Imikhomo ebizwa ngokuthi i-humpback izihambi zangempela. Zihlala kuwo wonke amalwandle omhlaba nezilwandle eziseduze. Zifuduka njalo futhi zihlala ikakhulukazi ezindaweni ezihlala ama-krill. Futhi ukufuduka kwezinkathi ezithile kuyaphawulwa. Lezi zilwane zasolwandle azikwazi ukutholakala kuphela emanzini ase-polar.
Ezilwandle zomhlaba, ochwepheshe bakhomba inani elikhulu labantu abayi-3 kanye nemihlambi ehlukanisiwe eyishumi yemikhomo ehlala ifuduka. Abantu basentshonalanga basuka e-Iceland naseLabrador baya emanzini aseNew England naseziQhingini zase-Antian.
Abantu baseMpumalanga bahlala oLwandle iBarents, emanzini aseNorway, nasentshonalanga ye-Afrika. Imihlambi yaseNtshonalanga nasempumalanga ingaqhamuka ngesikhathi sokufuduka. Bangakwazi ukulala emhlambini owodwa eduze kwama-Antilles. I-Pacific Ocean esenyakatho nayo iyikhaya lemihlambi ehlakazekile esuka eChukotka iye ogwini lwaseCalifornia, ogwini lwaseMexico, eHawaii naseJapan. Imfuyo eningi njengemihlanu ikhethe amanzi abandayo ase-Arctic aseNingizimu Nenkabazwe njengekhaya labo.
Ukubekwa kwale mihlambi imi kanje:
- umhlambi wokuqala utholakala ngasogwini lwaseNingizimu Melika kusuka entshonalanga;
- umhlambi wesibili uhlala emanzini asogwini lwaseNingizimu Melika ohlangothini olusempumalanga;
- owesithathu usemanzini aseMpumalanga Afrika naseduze nesiqhingi saseMadagascar;
- owesine uhlala emanzini aseNtshonalanga ye-Australia;
- omunye umhlambi uhlala ngasogwini lwaseMpumalanga ye-Australia.
Ensimini yezwe lethu, imikhomo yalezi zinhlobo ihlala olwandle lwaseJapane, eChukchi, eBerengovo naseBarents. Kuyiqiniso, muva nje inani lemikhomo yalezi zinhlobo lehle kakhulu, ezindaweni ezihlala kulezi zilwane kuya ngokuya kuncipha. Kusele imikhoma embalwa kuphela e-Barents Sea.
Iqiniso elithandekayo: Ukuze zikhululeke kuma-parasites, imikhomo i-humpback ivame ukungena emlonyeni wemifula yamanzi angenasawoti, lapho ikhululwa khona kuma-parasites ahlala emzimbeni womkhomo. Izimuncagazi azikwazi ukuhlala emanzini amasha bese ziyafa.
Manje uyazi lapho uhlala khona umkhoma. Ake sibone ukuthi lesi sidalwa esincelisayo sidlani.
Udlani umkhomo i-humpback?
Isithombe: Umkhomo omkhulu we-humpback
Imikhomo ebizwa ngokuthi i-humpback yizilwane ezidla ezinye futhi idla kakhulu kuma-crustaceans amancane, i-krill nezinhlanzi.
Ukudla okujwayelekile kwalezi zidalwa kufaka:
- i-krill;
- ama-crustaceans amancane;
- izimbaza;
- imfanzi neplankton;
- i-herring;
- capelin;
- ikhodi;
- chum;
- i-salmon ebomvana nezinye izinhlobo zezinhlanzi;
- izimila zasolwandle.
Izimpumputhe zondla ukuhlunga. Lezi zilwane zinamapuleti amakhulu omkhomo womkhomo, acishe ufane nesihlungo, esikhula emhlathini ongenhla. Lezi zingcwecwe ziqoqa ama-plankton, ulwelwe nezinhlanzi ezincane. Isilwane simane sivule umlomo waso omkhulu bese simunca amanzi amaningi kanye nama-plankton nezidalwa eziphilayo ezikuwo.
Ngemuva kokuba umkhomo uvale umlomo, amanzi ayahlungwa phakathi kwamapuleti womkhomo. Amafolda entamo ayeluliwe phambilini ayacindezelwa, ulimi lomkhomo luyakhuphuka. Ukudla kuhlala emabhulashini atholakala onqenqemeni lwangaphakathi lwethambo lomkhomo futhi kamuva kuginywe. Amanzi ayaphuma.
Iqiniso elithandekayoUmkhomo uyisidalwa esikhulu kakhulu futhi udinga ukudla okuningi. Isisu somkhomo singafinyelela ku-850 kg wezinhlanzi.
Imikhomo ithola ukudla kwayo ngezindlela ezahlukahlukene. Kwesinye isikhathi imikhomo izingela ndawonye izikole zonke zezinhlanzi. Imikhomo eminingi ibhukuda ngasikhathi sinye isiyingi bese ishaya amanzi ngezimpiko zayo, yakha indandatho enamagwebu lapho izinhlanzi zingakwazi ukubhukuda zilahleke esikoleni esisodwa esinyene.
Kulokhu, imikhomo iyashintshana ngokuntywila ngokujulile enkabeni yesikole sezinhlanzi futhi izama ukubamba inyamazane enkulu ngangokunokwenzeka. Lapho uzingela izinhlanzi ezingezansi nama-crustaceans, ama-humpbacks, ukukhipha amanzi, kwakha ifu legwebu emanzini avela ku-blowhole, lokhu kudiliza izinhlanzi phansi. Ngemuva kwalokho, umkhoma ucwila phansi, ugwinye ukudla.
Kwesinye isikhathi imikhomo iyodwa iyamangaza izinhlanzi ngokushaya okucijile komsila ebusweni bamanzi, kuyilapho umkhomo ubhukuda wenze isiyingi. Inhlanzi emangele ayiqondi ukuthi idinga ukubhukuda kuphi futhi iphinde ingene esikoleni, ngemuva kwalokho umkhomo ubambe isisulu sawo ngokungazelelwe.
Izici zobuntu nendlela yokuphila
Isithombe: Umkhomo i-Humpback olwandle
Impilo ye-humpbacks incike kakhulu ekufudukeni kwabo kwesizini. Ngenkathi yokukhwelana nasendaweni yazo ejwayelekile, imikhomo izama ukuhlala endaweni esogwini ekujuleni okungajulile. Bahlala kaningi ezindaweni zokuhlala i-krill. Endaweni efanayo, izilwane zikhuluphele zakha ungqimba oluqinile lwamafutha angaphansi kwesikhumba. Ngesikhathi sasebusika, imikhomo idla kancane kakhulu futhi ilahlekelwe isisindo sayo esifinyelela ku-30%.
Ebusika, imikhomo ifudukela ezindaweni ezinesimo sezulu esifudumele. Imikhomo ivame ukudlula ngasogwini lwaseMexico, eJapan naseColombia. Ngesikhathi sokufuduka, imikhomo ibhukuda izinkulungwane zamakhilomitha, kuyilapho umkhondo wemikhomo ulayini oqondile. Imikhomo ihamba kancane, ngesikhathi sokufuduka ijubane le-humpback lingaba ngu-10-15 km / h.
Imikhomo ebizwa ngokuthi i-humpback kubhekwe ukuthi ihlekise kakhulu futhi idlale kakhulu. Ama-backbacks ajwayele ukudala ukusebenza okuphelele ngokuziphonsa emanzini amamitha ambalwa, bese ebuyela emanzini ngokujabula. Ngesikhathi esifanayo, ama-humpbacks azungezwe amafu okufafaza. Lokhu kuziphatha ezilwaneni akubangelwa yimvelo yazo yokudlala. Imikhomo ayizijabulisi ngale ndlela, kodwa imane ilahle ama-parasites ahlala emzimbeni wayo. Imikhomo ayikwazi ukuhlala ngaphansi kwamanzi ngaso sonke isikhathi ngendlela ephefumula ngayo umoya.
Ehlobo, imikhomo icwilisa imizuzu engu-5-8. Ebusika, ngo-10-15 ezimweni ezingavamile, zingaba ngaphansi kwamanzi kuze kube isigamu sehora. Ama-Humpbacks ahlala ekhipha imithombo yamanzi ahlungiwe ngaphezulu ngezikhathi zemizuzwana emi-5-17. Imithombo emise okwe-V efinyelela kumamitha ayi-5 ukuphakama. Imikhomo ebizwa ngokuthi i-humpback inomoya opholile nobungane. Isakhiwo senhlalo yemikhomo asithuthukisiwe; imikhomo ngokuvamile igcina imihlambi emincane noma iyodwa. Imindeni ayakhiwa ngemikhomo, owesifazane kuphela onakekela inzalo. Isikhathi esiphilwa yimikhomo yama-humpback yiminyaka engama-40-50.
Isakhiwo senhlalo nokuzala
Isithombe: Umkhomo we-Humpback ovela eRed Book
Isikhathi sokukhwelana semikhomo i-humpback siwela ebusika. Phakathi nayo yonke inkathi yokukhwelana, kuzwakala ukucula okukhulu kwamadoda. Ngakho-ke baheha abesifazane, futhi babeke imingcele yezinto zabo kwabanye abesilisa. Kwesinye isikhathi ukucula kungaba yindlela ejwayelekile yokuxhumana.
Ngesikhathi sokukhwelana, imikhomo iba ngaphezu kobusika emanzini afudumele, kanti abesifazane abalungele ukukhwelana bahlala emanzini azolile avikelwe emimoyeni emanzini angajulile. Abesilisa bahlala besondele. Njengoba ikhethe insikazi, eyesilisa iyayijaha, ingavumeli abanye abesilisa ukuba basondele kuyo. Imvamisa kuba nokulwa phakathi kwabesilisa abalwela insikazi.

Ngemuva kokukhuluphala, imikhomo ibuyela emanzini afudumele. Ilapho, ngemuva konyaka cishe wokukhulelwa, kuzalwa izinyane elilodwa kwabesifazane. Umkhomo osanda kuzalwa unesisindo esiphakathi kuka-700 kg no-1.5 ton. Ukukhula kwezinyane ngesikhathi sokuzalwa kungamamitha ama-5. Insikazi yondla izinyane ngobisi ngonyaka wokuqala.
Iqiniso elithandekayo: Imikhomo eyizinsikazi yizona kuphela izilwane ezincelisayo ezikwaziyo ukuthwala nokondla ithole ngobisi ngesikhathi lapho yona ingenakho ukudla. Ngesikhathi sobusika ezindaweni ezishisayo, imikhomo cishe ayidli, futhi abesifazane bondla amawundlu abo ngobisi, olukhiqizwa emithonjeni yamafutha.
Ithole likhula ngokushesha okukhulu, kuthi ekugcineni kokulincelisa libe ngamamitha ayi-9 ubude. Ngalesi sikhathi, insikazi iyeka cishe zonke izinqolobane futhi yehlisa kakhulu isisindo. Ngesikhathi sokufuduka, izinyane liyabhukuda eduze kukanina. Imikhomo ifinyelela ekuvuthweni ngokobulili ngeminyaka eyisithupha. Insikazi izala izinyane elilodwa kanye njalo eminyakeni embalwa. Kwesinye isikhathi abesifazane bangakhulelwa ngesikhathi sokuncelisa, kepha lokhu kungaphansi kwezimo ezinhle kuphela.
Izitha zemvelo zemikhomo yama-humpback
Isithombe: Umkhomo i-Humpback
Imikhomo ebizwa ngokuthi i-humpback, ngenxa yobukhulu bayo obukhulu, ayinazo izitha endle. Ezitheni zemvelo zemikhomo, kungabonakala kuphela i-killer whale, engahlasela amawundlu emikhomo. Kodwa-ke, lezi zidalwa ezinkulu zinobuthi kakhulu ngama-parasites amancane.
Ama-parasites ajwayelekile ahlala emikhomeni afaka:
- ama-copepods;
- izintwala zomkhomo;
- ama-baleen crustaceans;
- izibungu eziyindilinga;
- ama-trematode;
- ama-nematode, ama-side-scrapers, njll.
Kepha isitha esikhulu salezi zidalwa ezinkulu sasiyindoda futhi sihlala siyindoda. Sekuyisikhathi eside imikhomo iyisizathu sokukhishwa ngemikhomo, futhi ngekhulu lama-20, cishe ama-90% alezi zilwane aqothulwa, manje ngenxa yokuzingela, sekuvinjelwe imikhomo. Kepha kuze kube manje, imikhomo eminingana iyabulawa minyaka yonke. Inyama yomkhomo yaziswa kakhulu, kanti nomkhomo whale nawo ubaluleke kakhulu, lapho kwenziwa khona izinto eziningi.
Ngokwethulwa kokuvinjelwa kokuzingela, inani lemikhomo seliqale ukusinda kancane kancane. Namuhla, ukukhathazeka okukhulu kubangelwa ukungcoliswa kwemizimba yamanzi okuhlala kuyo imikhomo. Ngenxa yokuguquka kwesimo sezulu kanye nokungcoliswa kwamanzi, ukungena kwamakhemikhali ayingozi emanzini, izinhlanzi kanye nama-crustaceans amancane, okuwukudla kwemikhomo, kuyafa. Ngaphandle kwalokho. imfucumfucu engaboli iyabambeka emgudwini wokugaya womkhomo, okungadala ukuthi isilwane sife.
Inani labantu kanye nesimo sezinhlobo
Isithombe: Ubukeka kanjani umkhomo i-humpback
Ngenxa yokuthi sekuyisikhathi eside abantu bezingela ngonya imikhomo yama-humpback, inani lalezi zidalwa ezimangalisayo lisengozini yokuqothulwa. Izibalo ziyadabukisa: kubantu abayi-150-120 abayizinkulungwane, kusala kuphela abantu abayizinkulungwane ezingama-30 kuya ku-60 emhlabeni wethu. Ngasikhathi sinye, inani lemikhomo ebizwa ngeNyakatho ye-Atlantic lehla lisuka ku-15,000 laya ku-700.
Umkhomo waseNyakatho Pacific ekuqaleni wawunabantu abangaba ngu-15 000, kodwa ngo-1976 inani labantu lase lehlele ku-1,500, nakuba ngo-1997 inani labantu lase lenyuke futhi laya ku-6,000. ENingizimu Nenkabazwe ngonyaka we-1965, kwakukhona abantu abayizinkulungwane eziyikhulu, okwamanje kunamakhanda ayizinkulungwane ezingama-20. ENorth Indian Ocean ngeminyaka yama-80s. kwakukhona abantu abangu-500 kuphela.
Ngemuva kokwethulwa kokuvinjelwa kokudoba, inani labantu ababuya emuva laqala ukusimama kancane kancane. Ngo-1990, lezi zinhlobo zazinesimo Esisengozini Yokuqothulwa Encwadini Ebomvu - izinhlobo ezazisengcupheni yokuqothulwa zashintshwa zaba sengozini (izinhlobo ezinabantu bazo abasesimweni esibucayi).
Usongo olukhulu emikhomeni okwamanje ludalwa yisimo esingesihle semvelo, ukungcoliswa kwamanzi nokuguquka kwesimo sezulu. Futhi, imikhomo i-humpback imvamisa iphelela emanethini okudoba, lapho ingeke iphume khona, futhi ishayisane nemikhumbi.Kwezindawo zokuzalela imikhomo, kunezinto eziningi ezivimbela lezi zilwane ukuba zikhiqize ngokuphepha, kufaka phakathi inani elikhulu lemikhumbi yokudoba, nenqwaba yezikebhe nezikebhe.
