Iminenga zizilwanyana ezanyisayo eziqhelene namanzi
Umnenga uvuselela nje ubukhulu bawo. Sisilwanyana esanyisayo, sithathwa njengomama, yintlanzi ehlala ifuna ukuza phezulu, kodwa ithanda nolwandle olunzulu.
Inxalenye yokutsala kwethu kwiminenga bubukhulu bayo
Asifane silifumane ithuba lokuwubona wonke umnenga ngaphandle kwaxa utsiba ngaphandle amanzi yenza.
Iminenga yenye yezona zidalwa zintsonkothileyo nezimangalisayo.
Malunga neetoni ezimalunga ne-100, umnenga oluhlaza sesona silwanyana sikhulu sakha saphila emhlabeni umhlaba uye waphila. Izodlula ngokulula ezona dinosaur zinzima. Kwanomnenga “oqhelekileyo” sisilwanyana esikhulu nesibalaseleyo.
Iminenga mikhulu kodwa inqabile kwaye kunzima ukuyibona, yongeza kwimfihlakalo kunye nesibheno sayo.
Zizilwanyana ezikrelekrele kakhulu ezinenkqubo yentlalo entsonkothileyo impilo, akukho mpahla kunye nenkululeko epheleleyo kwimisebenzi kwimilinganiselo ye-3.
Ngaba iyamangalisa into yokuba zizilo-qabane ezibalaseleyo nezinika umdla? – Mhlawumbi sifuna nje ukufana nabo.
Iminenga iyinxalenye yezidalwa ezibizwa ngokuba ziiCetaceans
Iminenga zizilwanyana ezanyisayo, abantu, izinja, iikati zasekhaya, Iindlovu kunye neAnguantibos.
Sie ukuphefumla Umoya kwaye ke ngoko kufuneka ubuyele kumphezulu ngamaxesha aqhelekileyo ukuze uphefumle. Bavusa abaphilayo Inkwenkwe Abantu abahlala behlala kunye nomama ngaphezu konyaka kwaye batye ubisi oluveliswa ngumama.
Iminenga inegazi elimnandi kwaye inamathambo anokuthelekiswa nowethu (nangona yahluke kakhulu).
Imilenze yangaphambili ngamaphiko awo angaphambili kwaye inamathambo afanayo kwiingalo nezandla zethu. Imilenze yangasemva ayiqhelekanga ukubakho xa iyonke, kodwa kwiindidi ezahlukeneyo imelwe ngamathambo amancinci “akhukulisekayo” (i-pelvic vestiges) – engadityaniswanga kwezinye – ngasemva kwesilwanyana sasekhaya.
Kumadoda eentlobo ezithile, la mathambo asebenza njenge-attachment ye-muscle mass elawula incanca.
IMinenga eBlue: uFrancisco kunye neBlue Whales-WWF IBali
Iminenga eBlue yingxilimbela elwandle. Zizodwa - zinobubele kwaye zintle ngokugqithisileyo. Banika ithemba. Joyina uFrancisco kukhangelo lwakhe lokukhangela esona silwanyana sikhulu ehlabathini: ▶ http://www.wwf.de/hoffnung-fuer-blauw… Ikhamera kunye nendlela: Anne Thoma

Amaphiko omnenga abizwa ngokuba zii<em>flukes, azinalo kwaphela ithambo kwaye zenziwe ngezinto ezintsonkothileyo ezinzima.
Zii-leeches ezibonelela ngamandla okuqhubela phambili kuzo zonke ii-cetaceans kunye nesikhokelo sokulawula sangaphambili kwaye sisetyenziselwa iinjongo zokunxibelelana kunye nokusebenza.
Yonke iminenga inobunzima bezihlunu kunye namanqanaba aphezulu e-myoglobin. Eli libala elibomvu elithelekiswa nehemoglobin egcina ioksijini kubunzima bezihlunu ukuze isetyenziswe ngexesha lokuntywila nzulu.
Xa i-whale iphezulu, i-oksijini kwi-myoglobin iyatshintsha, efana nenkqubo eyenzeka kwi-muscle mass yethu ngexesha le-sprint.
IWhale Shark Watch (Eyona ntlanzi inkulu ehlabathini)
I-whale shark (i-Rhincodon typus) ngoyena shark omkhulu kwaye ikwayeyona ntlanzi inkulu namhlanje. I-whale shark kuphela kweentlobo kwi-Rhincodon, i-genus kuphela kusapho lwe-Rhincodontidae. I-whale shark ikuhlobo lwee- sharks zabongikazi.
Oyena shark omnenga omde orekhodiweyo ukuza kuthi ga ngoku wawuziimitha ezili-13,7 ubude. Kukho iingxelo ezisekelwe ekubonweni kwabantu ukuya kwi-18 okanye i-20 m ubude, kodwa ezi mhlawumbi zisekelwe ngokuyinhloko kwi-overestimation kunye nokugqithisa, okuqhelekileyo okuqhelekileyo kwizilwanyana ezinkulu.
Kutshanje, malunga neemitha ezili-12 ubude besampulu IsiJaphani utsalwa elunxwemeni ngabalobi. I wenze ukuba ubunzima bayo malunga neetoni ezisi-8. Ookrebe banokuba nobunzima obungaphezu kweetoni ezili-12.
Njengookrebe abatya intlanzi kunye ne-basking mouth sharks, batya iplankton kunye nezinye iintsholongwane, ezizifumana ngokufunxa emanzini. amanzi isihluzo. Ngokutsho kohlolisiso lwakutshanje, bakwatya iintlanzi ezifikelela kubukhulu bemackerel kunye netuna encinane. Ngenxa yobungcali bokutya, lo krebe akanabungozi ebantwini, kodwa iingozi zingenzeka ngenxa yobukhulu kunye namandla ezilwanyana.
