Keith - intlanzi okanye sisilwanyana esincancisayo? iinyani ezinika umdla malunga iminenga

Keith - intlanzi okanye ezanyisayo? Lo mbuzo mayingakhathazeki izazinzulu elide ngaphambi kokufika bezenzululwazi. Ingakumbi, le ngxaki owayezama isigqibo ingcamango yingqondi enjalo, njengoko uAristotle. Kwaye weza efanayo kwisigqibo sokuba bexesha zethu. Kodwa sonke ukuze.

Keith - oku abemi abaninzi obubalaseleyo isibhakabhaka anzongonzongo. Ekubeni ubukhulu bayo kwaye ubabalo nanto yi nasiphi na isidalwa ephilileyo, singasathethi amandla akhe amangalisayo ukucula iingoma. Kodwa yintoni enye Sazi ngale ezi zidalwa emangalisayo?

Ngubani na lo mnenga?

Ngoko ke yintoni na intsingiselo sentlanzi enkulu? Ngokutsho isichazi-magama, sisilwanyana esincancisayo esikhulu ehlala elwandle. Oko kukuthi, ngokuchaseneyo elidlulileyo, ukufumana isisombululo umba onjalo bofanelana bephinyelene lula kakhulu. Kodwa ukuba kwenzeka njani ukuba inzala i womnenga wamandulo wayefuna ukutshintshiselana umhlaba olwandle?

Kaloku, yonke inyaniso, izazinzulu asazi. Nangona kunjalo, kuyaziwa ukuba kwiminyaka yezigidi-60 eyadlulayo iminyanya zonke iintlanzi, kuqala waya kufuna ukutya yabo emva emanzini. Mhlawumbi oku kuye kwakhokelela ekubeni ithuba elide yimbalela, abatshabalalisa yinxalenye kwezityalo emhlabeni, okanye eninzi yokhuphiswano kwezinye izilwanyana. Kodwa inyani - iminyanya kweminenga akusekho wayefuna ukuya kwelo zwe.

Njani isilwanyana umhlaba liye lakwazi ukuzivumelanisa ubomi kwamanzi?

Kufuneka kuqondwe ukuba ayaguquka loo nto yenzeke kule minyaka omnye okanye emibini. Evolution - yinto inxitywe lotshintsho ezincinane ezenza eminyaka eziphilayo esoloko mutating. Ekugqibeleni le uzala look entsha lonke, yahlukile ngokwesiseko ookhokho bayo.

Kodwa emva kweminyaka million 60, abaphandi kunjalo efumaneka kulwakhiwo skeleton whale ntlokoma kwabo bamaxesha amandulo, akuba wahamba ngamathupha azo ezine ilizwe. Ngokomzekelo, yena ithambo womlenze, nto leyo ibekwe kwinxalenye ngasemva lomzimba. Kwakhona, amaphiko ayo ngaphambili baye amathambo efanayo kunye uninzi izilwanyana uphuphu-ayabulala.

Ekugqibile inani lezifundo, izazinzulu ziye kufika esiphelweni ukwazi. Kubonakala ukuba izalamane abakhulu iintlanzi ezi iimvubu. Kwaye ukuba uyayijonga ngokusondeleyo, ezinye ezifana ngazo yokuziphatha zabo inokubonwa nanamhlanje. Ingakumbi umnqweno elikhulu amanzi.

Usapho of iintlanzi

Kufuneka kuqatshelwe ukuba umnenga - akukho ummeli kuphela intsapho yakhe. Amahlengesi porpoises nazo zibandakanyiwe udidi nezilwanyana zaselwandle. Njani ukuba ahluke kwabanye abemi enzulwini yamanzi?

• Okokuqala, bonke iminenga ishushu-zinegazi elibandayo, ngokungafaniyo iintlanzi. Yiyo loo nto udelekile kakhulu kangangokuba abadinga a amafutha emzimbeni vuyelo lebyinene lebyi nga ukuzikhusela abanomkhuhlane zobukumkani kwamanzi.
• Okwesibini, le ntsapho ayikho nako ukuwutsala ioksijini ngamanzi. Ngoko ke, ukuba ndisoloko ndibekwa kumphezulu, ukuze niwuzalise konikezelo umoya emiphungeni.
• Okwesithathu, ukondla abantwana babo ubisi. Nangona kule minyaka nasekusungulweni kwale nkqubo kancinane lingatshitshi, iintlanzi nangoku ezincancisayo.

Usapho lonke yahlulwe amaqela amakhulu amathathu:

• Iminenga ikhamisile (Mysticeti) - njengebutho inkulu entsapho. msebenzi wayo lokwahlula i filter umzimba "ngethambo" ezizodwa, apho ibekwe phezu emhlathini eliphezulu isilwanyana. umsebenzi wayo ophambili - nokuyicoca kwizidalwa ezivela ukungcola okungafunekiyo.
• Unamazinyo Iminenga (Odontoceti) - ngu kunye ezinkulu ezizingelayo, preying kwi squid kunye neentlanzi ezincinane. Olu hlobo uyakwazi ukuyisebenzisa emanzini usebenzisa amaza.
• iminenga yamandulo (Archaeoceti) - ngelishwa, hayi ummeli olunye kolu didi, ababa nakuhlala iintsuku zethu.

Iminenga: ulwazi ngokubanzi

Phakathi bonke abemi uMhlaba sentlanzi - esiyimamali inkulu. I-avareji ngamnye omdala unako ukufikelela-25 eemitha ubude. Thelekisa, cishe efanayo athathe iibhasi ezinkulu 4, ukuba bafake emgceni. Akumangalisi ukuba into enkulu kangaka inobunzima malunga 90-110 iitoni, abanye kakhulu.

Ezi zigebenga bahlala phantse zonke neelwandle kulo mhlaba. Yintoni oyinyaniso, banako abasuka kwindawo enye ukuya kwenye kuxhomekeka kwixesha lonyaka. Oku kuziphatha kungenxa yokuba kweminenga avelana lobushushu emanzini, kwaye bachitha kufutshane ekweleenjiko ngoko ebusika.

Lilonke, phakathi onke amalungu ale ntsapho zingahlukaniswa zenyathi avezwa: iminenga eluhlaza hina. Ngokubanzi, eli candelo kubangelwe ibala lolusu kwezi zilwanyana, kodwa zikho nezinye, umahluko ebaluleke kangako.

ntlokoma elidlulileyo

whale Grey - na ummeli mdala entsapho. Izazinzulu ziye zafumanisa iintsalela ezi izilwanyana uhlalutyo rough wayemalunga million 30 iminyaka. Ngaphambili, ezi ngxilimbela babehlala phantse kuzo zonke iimbombo zomhlaba, kodwa ngoku inokufumaneka kuphela kumntla we-Pacific Ocean.

Ezi zidalwa osetyenziswayo bahlala ngokwamaqela amancinane nama-2-3 abathile nganye. Nangona adibana rhoqo, kwaye ndiyingwenya elilolo ngokuziqhenya ukulima kwizikhewu amanzi. Ukanti uninzi Izigebenga bakhetha ukuhlala kwiqela. Ubukhulu becala oku kungenxa yokuba lo mnenga zingwevu leyo kakhulu kuphuhliswa ngamandla amaqhina entsapho.

Mhlawumbi olu umbutho libancede basinda kuloo maxesha anzima. Ngapha koko, phakathi kwinkulungwane XX zaphantse atshabalalisa sperm, bazingela nenqatha lazo. Ngoko ke, ngokutsho izazinzulu, ngo-1946 inani le ezincancisayo lancitshiswa kubantu-250. Kuphela yi ummangaliso, yaye imigudu abalwela amalungelo zezilwanyana wakwazi ukuphepha intlekele. Ke inani yezi zilwanyana liye lanyuka ukuya ku-30 amawaka., Oko wabanika ithemba esitsha nekamva elingcono.

whale Blue - isidalwa inkulu emhlabeni

Njengokuba iminenga oluhlaza okwesibhakabhaka, zithathwa ukuba izidalwa ezinkulu kulo mhlaba. Nokuba isilwanyana enkulu ezinjengezo indlovu, akakwazi ukuba bakhuphisane nabo. Ezi ubungakanani bayakhunjuzwa ukuba xa into efana iingxilimbela wahamba yonke phezu komhlaba. Ngoku, umnenga blue - ummeli kuphela izilwanyana yamaRefa yamandulo.

Esi silwanyana ayikho ingakumbi fan zabantu, yaye ke ngoko kunqabile loLawulo- unxweme. Lakhe medium ndiyithandayo kolwandle, apho avakalelwa nikhululekile inene. Ebuya kakhulu kancinci, kuphela kwisantya 10-12 km / h, kodwa kaxakeka oko ukwandisa nemihlambi emithathu.

Njengazo zonke amalungu iintlobo bakhe, umnenga blue feeds kwizidalwa. Kwaye nangona oku silwanyana iye endaweni kudala ilizwe phezu kwamanzi, ukuba uhlale kuyo, kusenjalo nanamhlanje asikwazi. Kungenxa yoko le nto iminenga ngokufuthi babhabha phezu kwamanzi, ngaloo ndlela yokukhulula amanzi emithonjeni lokuvula ekhethekileyo ibekwe kwi kumzimba ongentla.

imik yokuzala

Iminenga - izilwanyana elwandle, ogama amanani badla zancitshiswa kumanqanaba enkulu. Oku olubangelwa abantu babezingela inyama yazo kunye namanqatha. Kuyinto ukuba ngoobani na izinto eziphambili zezi ntlekele, kodwa hayi kuphela.

Enye into echaphazela abemi naluphi na uhlobo, kukuba layo nokuzala. Ngoko ke, le ngxaki iza kuxhomekeka kukuba ezi zidalwa inzala wazalwa hayi ngaphezulu kanye omnye okanye emibini. Ke kaloku ngoxa imazi uzale whale elincinane kuphela, ubuncinane - ezimbini. Kwangaxeshanye, kuxhomekeke ohlobo kweminenga ukukhulelwa unokuthatha phakathi kweenyanga 9 no-18.

Pleasant kukuba unina usoloko khathalela amathole ayo. Abo, ke, ukukhula ngokukhawuleza nokuba ubunzima. Ngoko ke, nge-avareji, ngosuku shorthead ndimzuze malunga-50 kg ubunzima. Ngoko ke musa ukumangaliswa ukuba ezinye iinyanga ezisixhenxe, yena uyakwazi vymahal ukuya ku-14 ubude, nobunzima 20-25 tonnes gama.

Kwaye nangona yiminenga ukufikisa eza eneminyaka engama-4-5, abantu, abadala yinxalenye ukuba 14-15 nje, ngonyaka ubomi bakhe.

Keith: Interesting Facts

Bambalwa abantu bazi ukuba:

• Iminenga - omnye umntu kuphela ngubani ukucula. Nangona ngaphambili kwakucingwa ukuba eli khono kuphela into eyindoda, izifundo kutshanje zingqineke eyahlukileyo. Ngoko ke, nathi, iminenga nemazi bacule iingoma, ingakumbi alimele kancinane.
