Isingeniso: Izilwane ezinegazi elifudumele kanye Nokuzalwa Okuphilayo
Izilwane ezinegazi elifudumele, ezaziwa nangokuthi izilwane ze-endothermic, yilezo ezikwazi ukulawula izinga lokushisa lomzimba wazo ngaphakathi. Ukuzalwa okuphilayo kuyisu lokuzala lapho inzalo izalwa iphila futhi ikhule ngokugcwele, ngokuphambene nokuchanyuselwa eqandeni. Kunezinhlobo eziningana zezilwane ezinegazi elifudumele ezizala ukuphila zisencane, kuhlanganise nezilwane ezincelisayo, ama- marsupials, nezinye ezihuquzelayo. Lesi sihloko sizohlola amaqembu ahlukene ezilwane ezinegazi elifudumele ezizala ukuthi ziphile zisencane.
Izilwane Ezincelisayo: Iqembu Elikhulu Lezilwane Ezinegazi Elifudumele Ngokuzalwa Okuphilayo
Izilwane ezincelisayo ziyiqembu elikhulu lezilwane ezinegazi elifudumele ezizala ukuphila zisencane. Zibonakala ngokuba khona kwezindlala zebele ezikhiqiza ubisi kubantwana bazo. Izilwane ezincelisayo zingatholakala ezindaweni ezihlukahlukene, kusukela olwandle kuya emahlathini, futhi zihlanganisa izilwane ezifana namabhubesi, amahlengethwa, nabantu. Isikhathi sokumitha kwezilwane ezincelisayo siyehluka kakhulu, sisukela emasontweni ambalwa kuya ngaphezu konyaka, kuye ngezinhlobo zezilwane.
Ama-Marsupials: Izilwane Ezihlukile Ezinegazi Elifudumele ezinezikhwama Zabasha
Ama-Marsupial yiqembu eliyingqayizivele lezilwane ezinegazi elifudumele ezizala ukuze ziphile zisencane. Ngokungafani nezilwane ezincelisayo, ama-marsupial anesikhathi esifushane sokukhulelwa, futhi inzalo yawo izalwa esimweni esingakathuthuki. Amaphuphu abe esekhasa esikhwameni sikamama, lapho eqhubeka khona nokukhula futhi ondliwe ubisi oluvela ezindlaleni zikamama zebele. Ama-Marsupial atholakala ikakhulukazi e-Australia, futhi ahlanganisa nezilwane ezinjengama-kangaroo, ama-wallabies, nama-possum.
I-Monotremes: Izilwane Ezalela Iqanda Elifudumele
I-Monotremes iyiqembu lezilwane ezinegazi elifudumele ezibekela amaqanda, kodwa futhi zizala ukuze ziphile zisencane. Lezi zilwane zitholakala kakhulu e-Australia naseNew Guinea, futhi zihlanganisa i-platypus ne-echidna. I-Monotremes ihlukile ngoba inembobo eyodwa yokukhipha nokuzala, ebizwa ngokuthi i-cloaca. Amaphuphu achanyuselwa eqandeni bese enikwa ubisi lukamama, yena alukhiphe esikhumbeni sakhe.
I-Eutherian: Izilwane Ezincelisayo Ezihlala Ngaphansi Ezinokuzalwa Okubukhoma
I-Eutherian iyiqembu lezilwane ezinegazi elifudumele ezizala ukuhlala zisencane, futhi zibonakala ngokuba khona kwe-placenta. I-placenta iyisitho esikhula ngesikhathi sokukhulelwa futhi inikeza ukuxhumana phakathi kukamama nengane ekhulayo, okuvumela ukushintshaniswa kwemisoco kanye nemfucuza. Ama-Eutherian ahlanganisa izilwane ezinjengezinja, amakati, nezindlovu, futhi anesikhathi eside sokukhulelwa kunama-marsupials, kusukela ezinyangeni ezimbalwa kuya ngaphezu konyaka.
Izimpungushe: Izilwane ezinegazi elifudumele Ezizala Inzalo Eyodwa
Ama-primates yiqembu lezilwane ezinegazi elifudumele ezizala ukuthi ziphile zisencane, futhi zibonakala ngezithupha zazo eziphikisayo, amehlo abheke phambili, kanye nokuziphatha komphakathi okuyinkimbinkimbi. Ama-primate anesikhathi eside sokumitha, esisukela ezinyangeni eziyisithupha kuya kweziyisishiyagalolunye, kuye ngezinhlobo zezilwane. Ngokungafani nezinye izilwane ezincelisayo, izinkawu ngokuvamile zizala ingane eyodwa ngesikhathi, eziyinakekela kakhulu.
Izilwane ezidla inyama: Izilwane ezinegazi elifudumele ezinamasu ahlukahlukene okuzala
Izilwane ezidla inyama ziyiqembu elihlukahlukene lezilwane ezinegazi elifudumele ezizala ukuphila zisencane, futhi zihlanganisa izilwane ezifana namabhubesi, amahlosi namabhere. Izilwane ezidla inyama zinezinhlobonhlobo zamasu okuzala, anezikhathi zokumitha ezisukela ezinyangeni ezimbalwa kuya ngaphezu konyaka, kuye ngohlobo. Ezinye izilwane ezidla inyama, njengezinja namakati, zizala amalitha, kanti ezinye, njengamabhubesi namahlosi, ngokuvamile zizala iwundlu elilodwa ngesikhathi.
Amagundane: Izilwane Eziningi Ezinegazi Elifudumele ezinezikhathi Ezifushane Zokukhulelwa
Amagundane yiqembu lezilwane ezinegazi elifudumele ezizala ukuphila zisencane, futhi zibonakala ngokukhula kwazo okungapheli. Amagundane anesikhathi esifushane kakhulu sokukhulelwa, kusukela emasontweni ambalwa kuya ezinyangeni ezimbalwa, kuye ngezinhlobo zezilwane. Baphinde babe ngabafuyi abakhiqizayo, kanti ezinye izinhlobo zizala amalitha angaba ngu-20 ngesikhathi. Amagundane ahlanganisa izilwane ezifana namagundane, amagundane, nezingwejeje.
Amalulwane: Izilwane Ezincelisayo Kuphela Ezinokuzalwa Okubukhoma
Amalulwane ayiqembu eliyingqayizivele lezilwane ezinegazi elifudumele ezizala ukuphila zisencane futhi yizona kuphela izilwane ezincelisayo ezikwazi ukundiza ngokuqhubekayo. Amalulwane anesikhathi eside sokukhulelwa, esisukela cishe emavikini ayisithupha kuya ezinyangeni eziyisithupha, kuye ngezinhlobo zezilwane. Amalulwane avame ukuzala ingane eyodwa ngesikhathi, kanti amaphuphu agadwa umama aze akwazi ukundiza nokuzingela.
Izindlovu: Izilwane Ezinegazi Elifudumele Ezikhulelwe Isikhathi Eside Nokuzalwa
Izindlovu ziyiqembu lezilwane ezinegazi elifudumele ezizala ukuphila zisencane futhi ziyizilwane zasemhlabeni ezinkulu kunazo zonke emhlabeni. Izindlovu zinesikhathi eside sokumitha, esihlala cishe iminyaka emibili, futhi ngokuvamile zizala ithole elilodwa ngesikhathi. Ukuzalwa kwethole lendlovu kuyisenzakalo esibalulekile, lapho umhlambi wonke uqoqana ukuze usize umama phakathi nenqubo.
Imikhomo: Izilwane zasemanzini ezinegazi elifudumele ezinokuzalwa okubukhoma
Imikhomo iyiqembu lezilwane ezinegazi elifudumele ezizala ukuphila zisencane futhi ziyizilwane ezinkulu kunazo zonke emhlabeni. Imikhomo inesikhathi eside sokumitha, esihlala cishe izinyanga eziyi-10 kuya kweziyi-18, kuye ngezinhlobo zezilwane. Imikhomo ivamise ukuzala inkonyane elilodwa ngesikhathi, kanti amazinyane anakekelwa ngunina aze akwazi ukubhukuda nokuzingela.
Isiphetho: Ukwehlukahlukana Kwezilwane Ezinegazi Elifudumele Ezizala Ukuze Ziphile Zisencane
Sengiphetha, kunamaqembu amaningi ahlukene ezilwane ezinegazi elifudumele ezizala ukuze ziphile zisencane, ngayinye inamasu nezici zayo zokuzala eziyingqayizivele. Kusukela kuma-marsupial anezikhwama zawo zabancane kuye emikhomo ezalela olwandle, lezi zilwane ziye zajwayelana nendawo ezikuyo ukuze ziqinisekise ukuphila nokukhula kwabantwana bazo. Ukuqonda ukuhlukahluka kwalezi zilwane kungasisiza ukuba sazise inkimbinkimbi nezimangaliso zendalo esizungezile.
