Ngaba uyawazi umnenga waseMazantsi? Ewe, siyakuxelela ukuba yi-cetacean yosapho lweminenga ye-baleen, enobungakanani obukhulu kunye nobunzima obunzima, oyenza ibe sesinye sezona zilwanyana zibalaseleyo emhlabeni kwaye ihlala kumanzi abandayo kakhulu, kodwa ukuba ufuna yazi ngakumbi, qhubeka ufunda le post.
Umnenga oLungileyo waseMzantsi, ngaba uyahlalisana?
Umnenga osezantsi unomdla kakhulu kwaye uyadlala xa ujikeleze abantu. Kukho iimeko apho baye bafuna ukuthwala iinqanawa ezincinci kunye ne-kayak emqolo. Kuqhelekile ukuba basebenzisane ngendlela yobuhlobo kunye namahlengesi kunye neminenga ye-humpback.
Ezinye iinyani malunga ne-Southern Right Whale
- Ummandla: Antarctica
- Iindawo zokuhamba: Antarctic Peninsula, Falkland Islands, South Georgia Islands, Tristan da Cunha
- Igama: umnenga osemazantsi (Eubalaena australis).
- Ubude: 15 yeemitha.
- Ubunzima: 47 iitoni.
- Ukusasazwa: Amanzi akwi-subtropical kunye ne-sub-Antarctic kwi-hemisphere esemazantsi.
- Isimo soLondolozo: inkxalabo encinci.
- Ukutya: iicopepods kunye nekrill.
- Imbonakalo: ingwevu emnyama okanye emnyama, ngamanye amaxesha inamabala amhlophe ngaphantsi.
Iyondla njani?
Umnenga osekunene wasezantsi, njengoko sele sitshilo, ngowentsapho yeminenga ye-baleen. Ukuze zitye, ziginya amanzi azele ngumlomo zize zivale imilomo yazo ukuze ziwakhuphe ngeepleyiti ezikhethekileyo ezaziwa ngokuba ziibarbs, ezikwaziyo ukusefa amanzi nokugcina ukutya. Ukutya okuvaleleke kwi-baleen koko kufakwa kamva.
Nangona kunjalo, iminenga esemazantsi inomahluko kwiminenga yabo kwaye oko kukuthi, idada phakathi kwezikolo zekrill kunye nemilomo evulekile, kwaye ikwazi ukuhluza i-krill ngeli xesha ihamba phambili, ngaphandle kokuginya imilomo emikhulu yamanzi. .
Ukukhawuleza kangakanani ukuqubha?
Ngokutsho kophando, i-whale elungileyo iyacotha, kuba i-avareji iqubha ngesantya seekhilomitha ezi-5 ngeyure.
Anjani amasiko okuthandana ngaphambi komtshato?
Abasetyhini bafikelela ekukhuleni ngokwesondo malunga ne-9 leminyaka ubudala. Zizala qho emva kweminyaka emi-3 okanye emi-4 kuphela. Ixesha lazo lokuzala liqala phakathi kuJulayi ukuya kuAgasti.
Imazi ingqongwe ngamadoda anothando. Imazi iyakujikelezisa ijongise emqolo ukuze igcine amalungu ayo angasese ephakame, ngaphandle kwamanzi, kwaye ingafikeleli kwiinkunzi de izive ikulungele ukuzala. Ukudibanisa akusoloko kuphunyezwa ngenxa yeempawu ezikhethekileyo zendoda yendoda, eyi-3 yeemitha ubude kwaye iqhutywe.
Iinkunzi, xa zingalwi, ziyatyhalana ukuze zifikelele kwimazi. Xa sele ilungile, imazi inika ufikelelo oluninzi kumadoda. Iinkunzi ziya kuthi ke zivelise igaloni yamadlozi, eyomeleleyo ngokwaneleyo ukodlula amadlozi eenkunzi ezandulelayo. Ixesha lokumitha lithatha unyaka wonke kwaye xa lizelwe, ithole linobunzima obumalunga ne-1.500 yeekhilogram.
Uphila ixesha elingakanani iSouthern Right Whale?
Kukho ingcamango yokuba i<em>southern right whale iphila ngokomlinganiselo malunga neminyaka engama-50 endle, kodwa inkcazelo ekhoyo inqabile yaye kukho imizekelo yeentlobo ezifanayo eziphila ukuya kutsho kwiminyaka eli-100 ubudala.
Ngokutsho koko kuye kwaphawulwa, kukho malunga ne-10.000 XNUMX iminenga ekuthiwa yi<em>southern right whales ehlabathini.
Ngaba iSouthern Right Whale inamarhamncwa endalo?
Into eyaziwayo kukuba i-southern right whale ihlaselwa ngamangabangaba asePatagonia. Iingabangaba zenza inani elikhulu lamanxeba kuzo, zishiya imingxuma emikhulu kwisikhumba seminenga. Kwakhona, ngenxa yoku konzakala, iminenga ichitha ixesha layo elininzi ibaleka amangabangaba, nto leyo ethetha ukuba ichitha ixesha elincinane isondla amathole. Amathole awo asengozini kwiminenga ebulalayo nookrebe abakhulu abamhlophe.
Iinyaniso ezili-10 ezingundoqo malunga ne-southern right whale
Iminenga ibaluleke kakhulu kwiilwandlekazi. Kunokuthiwa ziinjineli ze-ecosystems, kuba zisebenzisana ngeendlela ezininzi ukugcina ubomi elwandle busempilweni, ngokusasazwa ngokutsha kwezondlo kwiilwandle kwiindlela ezahlukeneyo.
Umnenga ongasentla wenza umsebenzi ofanayo. Kodwa namhlanje ikhaya labo elikumanzi azwenibanzi kuMzantsi weAtlantiki lisongelwa kushishino lokuloba. Kweli candelo leposi siza kukuxelela iinyani ezilishumi malunga ne-southern right whale eya kuba nomdla kuwe.
1.- Igama layo ngu-Eubalaena australis: Yintlobo ye-cetacean yosapho lwe-Balaenidae, indawo yayo yokuhlala ifumaneka kumazantsi e-hemisphere, phakathi kwe-20 ° kunye ne-60 ° latitude kuMzantsi Pacific, eMzantsi Atlantic kunye noLwandlekazi lwaseIndiya.
2.- Ngomnye weminenga emikhulu: Banomlinganiselo ophakathi kwe-13 kunye ne-15 yeemitha ubude kwimeko yamadoda kwaye malunga neemitha ezili-16 kwabasetyhini. Ubunzima bazo bumalunga neetoni ezingama-40 kwaye ekuzalweni sele benobude obuziimitha ezi-3 ukuya kwezi-5, ukusuka empumlweni ukuya emsileni.
3.- Zinerhashalala eluswini zazo ezaziwayo kuba zisebenza okweminwe, ngazo umnenga ngamnye unokubonwa ubomi bawo bonke. Ezi calluses ziindawo eziphakamileyo zesikhumba, ezingaphezulu kwe-5 centimeters ubukhulu, ezibonakala kwiindawo ezahlukeneyo zentloko yazo.
4.- Zizilwanyana ezanyisayo ezolile kakhulu, zinomdla kwaye zicotha kakhulu ukudada. Ukuze banxibelelane benza imitsi baze babethe amanzi ngamaphiko abo.
5.- Kucingelwa ukuba banokuphila phakathi kwe-50 kunye ne-100 yeminyaka ubudala.
6.- Abanamazinyo, kodwa i-baleen ende, engamaphepha e-keratin ajinga kumhlathi ongaphezulu womnenga. Ezi barbs zizo ezivumela ukuba zondle ngokuhluza, njengoko sesichazile ngaphambili.
7.- Ukutya kwabo okuphambili yi-krill kunye neentlanzi ezincinci.
8.- Isinye kwisithathu sayo yonke iminenga elungileyo ehlabathini isebenzisa amatheku akhuselweyo eValdés Peninsula, eArgentina, njengendawo yokuhlala yokukhwelana nokuzala amantshontsho awo phakathi kwenyanga kaMeyi ukuya kuDisemba.
9.- Le minenga ingabonwa eArgentina, kwi-Valdés Peninsula, e-Australia, eMzantsi Afrika, eChile, e-Uruguay, e-Tristán de Acuña, exhomekeke kwi-British phesheya kwezilwandle naseNew Zealand.
10.- Ngokungafaniyo neNorth Atlantic kunye neNorth Pacific right whales, esengozini yokuphela, i-southern right whale iye yakwazi ukubuyisela kwiinkulungwane zokuzingela ngokurhweba.
