I-Koala iyisilwane esithandekayo ngokuphelele, esingavamile futhi esiyingqayizivele.
I-koala ihlala kuliphi izwekazi?
Ibhere le-koala marsupial liwuphawu futhi likhona e-Australia futhi, ngenxa yobuhle bayo obungajwayelekile, lihlala eziqiwini futhi libhalwe kuRed Book. Ibhere lifana nethoyizi eliphambili ongafuni neze ukulidedela. Isilwane esithandekayo satholwa ngabantu baseYurophu ngekhulu le-19 futhi kusukela lapho sithathwa njengesithandwa kakhulu emhlabeni wonke.
Izici ezijwayelekile ze-koala
Naphezu kokuthi i-koala ibizwa ngokuthi ibhere lase-Australia, lesi silwane asihlangani ngalutho nezilwane ezisabekayo. Abamele izilwane ezidla utshani bangabomndeni wama-marsupial. Ukubukeka kwesilwane akujwayelekile impela: uboya obukhulu nobufushane bomthunzi ompunga noma obhemayo, isisu esimhlophe, isisindo esincane (kufika ku-14 kg) nobude bomzimba obucishe bube ngamasentimitha angama-85. I-koala inamehlo angaboni kahle ngenxa yamehlo amancane nofiphele. Lokhu kulahlekelwa kunxeshezelwa ngokuphelele ngokuzwa nangephunga elihle kakhulu. Izilwane zinamadlebe amakhulu atholakala emaphethelweni ekhanda nasempumulweni emnyama emnyama.
Imvelo yenze isiqiniseko sokuthi ama-koala adla kalula utshani, kwakheka isakhiwo esihle samazinyo sale nqubo. Isici samabhere yimilenze yaso yangaphambi kokuqina nezinzipho zayo ezinde, ezivumela izilwane ukuba zihambe ngokukhululeka futhi zihlale ezihlahleni. Izilwane zinemilenze ekhule ngokuthakazelisa: ezingaphambili zinezithupha ezimbili ze-biphalangeal nezintathu ezijwayelekile (ezinama-phalanges amathathu). Izingemuva zinesithupha esisodwa nezinzwani ezine ezijwayelekile (azikho izipikili). AmaKoala nawo anomsila omncane ocishe ungabonakali ngaphansi kwejazi.
Indlela yokuphila yezilwane nomsoco
AmaKoala yizilwane ezithanda ubumnyama ezikhetha ukulala emagatsheni ezihlahla emini. Ama-Marsupials azolile, ama-phlegmatic, izilwane ezinesimo esihle. AmaKoala athanda impilo eyedwa, ngisho nokuzibandakanya futhi axhuma kuphela ngenhloso yokuzalanisa. Isilwane ngasinye sinendawo yaso ehlukile, engamukeleki ukwephulwa, ngaphandle kwalokho ukusabela okunolaka kungalandela.
AmaKoala angadli imifino kuphela. Bathanda ukudla amaqabunga e-eucalyptus, amahlumela nezinye izitshalo. Izitshalo eziningi ezidla imifino azinandaba nalezi zinhlobo zezimbali, ngoba ziqukethe inani elincane lamaprotheni ne-hydrocyanic acid. Isilwane esikhulile singadla kuze kufike ku-1.1 kg wamaqabunga ngosuku. AmaKoala aphuza okuncane kakhulu futhi kwabanye, kwanele ukujabulela amazolo asekuseni ukuqeda ukoma kwawo.
Amaqiniso athakazelisayo ngamabhere
AmaKoala abhekwa njengezilwane ezihlala phansi, ezichazwa yisilinganiso esiphansi semethabhodi emzimbeni. Kodwa-ke, ama-marsupials ayakwazi ukugijima futhi agxume kakhulu ukusuka esihlahleni esisodwa kuya kwesinye.
Izitshalo eziningi ezidla utshani azikwazi ukudla u-eucalyptus ngoba iqukethe izinto ezinobuthi ngobuningi obonakalisayo. Emzimbeni wama-koala, izinhlanganisela ezingezinhle ziyancishiswa, futhi amabhere azizwa emuhle.
AmaKoala yizilwane ezinokuthula. Kodwa-ke, abakwazi ukuziqhayisa ngempilo ephephile. Amabhere kaMarsupial avame ukugula, kufaka phakathi i-sinusitis, i-cystitis, i-cranial periostitis, ne-conjunctivitis. Emadolobheni amaningi kunezikhungo ezikhethekile lapho kulashwa khona izilwane ezigulayo.
Amabhere ase-Australia amile noma adla cishe sonke isikhathi. Bakhetha ukuba bodwa, ngakho-ke cishe abenzi imisindo. Kodwa-ke, uma kunesidingo, izilwane zingamemeza futhi zibhonge.
Lapho isilwane sicindezelwe ngokumelene nesihlahla, i-thermoregulation ivela. Isibonelo, lapho kushisa, ama-koala akhwela i-acacia, njengoba lesi kuyisihlahla esipholile kunazo zonke.
Izilwane ezincelisayo zinamaphethini ayingqayizivele ezandleni zazo ukuze zibonakale.
Ukuzalela ama-koala
Amabhere angamadoda angama-marsupial anepipi elinezimfoloko, kanti abesifazane banezitho zangasese ezimbili ezinezindlovukazi ezihambisanayo. Naphezu kwalokhu, i-koala ivamise ukuba newundlu elilodwa.
Isikhathi sokuzalela amabhere siqala ngo-Okthoba futhi sithatha kuze kube nguFebhuwari. Abesifazane ngokuzikhethela bakhetha abalingani babo. Indlela yokukhetha ithonywe usayizi wesilisa kanye nevolumu yokukhala kwakhe. Ngokwemvelo, kunabesilisa abambalwa kakhulu phakathi kwama-koalas kunabesifazane. Ngakho-ke, owesilisa oyedwa angaba nobuhlobo nabesifazane abathathu noma abahlanu.
I-Koala ithwala ithole izinsuku ezingama-30 kuye kwangama-35. Kuyinto engavamile kakhulu ukuthi kuzalwe amabhere amabili ama-teddy. Iqiniso elithandekayo ukuthi owesifazane angakhulelwa kanye kuphela eminyakeni emibili. Ngesikhathi sokuzalwa, ama-koala awanaboya futhi ezinsukwini zokuqala angaphansi kokunakekelwa okuphelele kukanina (baphuza ubisi lwebele futhi bahlala esikhwameni njengekhangaru). Ngokuhamba kwesikhathi, amaphuphu akhuphuka isikhafu sikanina, abambelele ngokuphepha noboya. Ekupheleni konyaka wokuqala wokuphila, ama-koala amancane alungele ukuhlala ngokuzimela, kodwa eminye iminyaka eminingana asondele kunina. Esikhathini esizayo, amabhere ashiya ikhaya lawo unomphela ayobhukuda "mahhala".
AmaKoala yizilwane ezimangalisayo ezizwayo futhi zizwe ubuhlungu njengabantu. Bangakhala kakhulu nangokuhlanya, okuhambisana nokuthuthumela.
