Izici zabameleli bekilasi le-amphibian nokuthi ixoxo lihluke kanjani kuxoxo

Ngokombono owamukelwa kabanzi wokuziphendukela kwemvelo, ukuphila eMhlabeni kwavela ekujuleni kolwandle. Ezigidini eziningi zeminyaka, emzabalazweni oqhubekayo wokuba khona, izinhlobo zezinto eziphilayo zavela futhi zanyamalala, zadedela ezintsha, eziphelele kakhudlwana, zinezindlela ezingcono kakhulu zokusinda. Futhi isikhathi eside, ezinhlobonhlobo zezilwane, okuwukuphela kwendawo yokuhlala kule planethi kwakuyisici samanzi. Kodwa isikhathi sesifikile futhi ukuthuthukiswa komhlaba sekuqalile. Amaphayona aphelelwe ithemba kancane kancane, kusukela esizukulwaneni kuya esizukulwaneni, ashintsha, esusa okungadingekile futhi ethola okudingekayo ukuze abe nokuphila okunethezeka emanzini: amaphiko aphenduka ama-paws, isitho esisha sokuphefumula sabonakala sithatha indawo yama-gill - amaphaphu.

Namuhla, imvelo ishaya emcabangweni ngobuningi obumangalisayo nokwehlukahlukana kwezinhlobo zezinto eziphilayo endaweni yasemanzini nasemhlabeni, futhi okwedlule kudlulele ekujuleni okungenakufinyeleleka kangangokuthi kunzima ukukholelwa ekubambekeni kwenkolelo-mbono uma ingekho. ubufakazi obuphelele. Kodwa kukhona ubufakazi, futhi lezi akuzona izinto zakudala zemivubukulo nhlobo, kodwa izidalwa eziphilayo wonke umuntu azijwayele.

Kumayelana nekilasi ezihlala emanzini noma ezihlala emanzini. Isayensi ithi abameleli baleli klasi bayisixhumanisi esiphakathi kwezinhlanzi nezilwane ezihuquzelayo. Obani abakha leli klasi? Yebo, izinhlobo ezivame kakhulu ezihlala emanzini ama-amphibian amaxoxo namaxoxo. Ngempela, ekuphileni komuntu ngamunye walolu hlobo lwalezi zinhlobo, kwenzeka i-metamorphosis emangalisayo: ukuguqulwa kwe-tadpole ehlala emanzini enamaphiko nama-gill ibe isilwane sasemhlabeni, iphefumula ngamaphaphu futhi ifakwe izidladla ezine ezithuthukisiwe. Futhi lokhu akuwona yini ukubonakaliswa okucacile kokuphuma kwezinhlanzi emhlabathini?

Izici ezithakazelisayo zesici ezihlukanisa abameleli bekilasi lama-amphibians kwezinye izilwane. Phakathi kwazo gqamisa izici eziyinhloko:

• ukukhiqizwa ngamaqanda abekwe emanzini,
• ukuphefumula ngamagill - esigabeni sama-tadpoles,
• ukushintshela ekuphefumuleni ngamaphaphu esigabeni sokuphuma emanzini,
• ikhono lokuphefumula ngesikhumba,
• ukungabi nezinwele, izimpaphe noma amazenga esikhumbeni.

Ngemva kokujwayelana nekilasi lama-amphibians, umbuzo uphakama nakanjani, okuyinto umehluko phakathi kwamaxoxo namaxoxo. Futhi, kuvela, akunzima ukubona umehluko, bheka nje eduze.

Umehluko Oyinhloko Phakathi Kwamaxoxo namasele

ukubukeka

Okukhona izimpawu zangaphandle eziningana ezivezayo, okwenza kube lula ukuhlukanisa amaxoxo kumaxoxo:

• Into yokuqala eheha ukunakwa yisikhumba. Emaxoxo, ibushelelezi, iyashelela, imanzi. I-hydration eqhubekayo igcina ikhono eliyingqayizivele lamaxoxo lokuphefumula esikhumbeni sawo. Emaseleni, isikhumba somile, sifakwe i-keratinized, simbozwe ngama-tubercles, okuthi, lapho ecasukile, akhiphe i-caustic poisonous mucus. Amaxoxo awanawo amandla okuphefumula ngesikhumba sawo. Inqubo yokuphefumula yomuntu omdala ihlinzekwa ngamaphaphu.
• Umbala wesikhumba samaxoxo uluhlaza, onqunywa indawo yawo yokuhlala, ngoba isikhathi esiningi achitha emanzini, phakathi kokuluhlaza kwezitshalo zamaxhaphozi. Amaxoxo asemhlabeni anombala onsundu, ovumela ukuba angabonakali, ahlangane nomhlabathi, ahlale emgodini omanzi phakathi nosuku. Emaxoxo kubaluleke kakhulu ukucasha, ngoba ayihlali eduze namanzi, lapho ingatshuza khona uma kwenzeka ingozi, futhi ayikwazi ukugxuma njengexoxo.
• Kunomehluko obonakalayo ekwakhiweni komzimba. Izilinganiso zesele ziba zinde kakhulu, ikhanda liphakanyiswe phezulu futhi lelulelwe phambili. Ngenxa yemilenze yayo yangemuva emide futhi eqinile, ibukeka iqinile, iluhlaza, futhi iyakwazi ngempela ukuhamba ngokushesha ngokugxuma okukhulu. Ngakolunye uhlangothi, isele libonakala lixega, liqhinqe, futhi lixakile. Umzimba wakhe ukhuluphele ucindezelekile phansi, ikhanda lakhe liyisicaba, imilenze yakhe mifishane futhi ibuthakathaka. Yingakho ixoxo linyakaza licishe likhase, ngezikhathi ezithile leqa kakhulu.
• Uma uhlola ngokucophelela amehlo exoxo, ungabona ukuthi umfundi wakhe, ngokungafani nexoxo, ude, ohlotshaniswa nendlela yokuphila yasebusuku.
• Esinye sezibonakaliso eziqinisekile ezihlukanisa ixoxo nexoxo amazinyo. Cishe zonke izinhlobo zamasele zinamazinyo amancane, kuyilapho amasele engakaze abe nawo.

Ukuphila

Amaxoxo achitha isikhathi esiningi sokuphila kwawo emanzini, ezingela emini, ethanda ukubamba izinambuzane ezindizayo noma izinyoni ezincane zamanzi. Ngemva kocingo lwakusihlwa, balala kwaze kwaba sekuseni. Amaxoxo, ngokuphambene nalokho, acasha emhlabathini emini, futhi hamba uyozingela ebusuku, ngenjabulo enkulu ukudla ama-slugs, amabhungane, izibungu nezibungu, okuyinto, ngendlela, ehlinzeka ngosizo olubalulekile kubantu ekulweni nezinambuzane ezingadini nezihlahla zezithelo.

Ukukhiqiza

Kokubili amaxoxo namaxoxo azala ngokubekela amaqanda. Uma izigaxa ezacile zintanta ebusweni bechibi, khona-ke cishe lena yi-caviar ebekwe yixoxo. Amasele abekela amaqanda ngendlela yezintambo ezinde ezigoqa izihlanga zolwelwe. Ezinye izinhlobo zaziwa ngokubonisa ukunakekela okukhethekile enzalweni.

Ngokwesibonelo, ixoxo wesilisa, elivamile eYurophu, ivunguza izintambo ezinamaqanda onyaweni futhi ihlala emgodini wobumba, ilindele ukuqala kokuchanyuselwa, ngemva kwalokho ithwala inzalo iyise echibini. Futhi ummeleli wamaxoxo avela eLatin America uhlukaniswa yiqiniso lokuthi uthwala inzalo ekucindezelekeni okukhethekile emhlane wakhe. Lokhu kunikeza amathuba amaningi okusinda kwezilwane ezincane, ngoba baningi abathandi be-caviar entsha abahlala emanzini.

Kubalulekile ukukhumbula ukuthi wonke amaxoxo namaxoxo ahlala ezindaweni eziphakathi nendawo awayona nje ingozi kubantu, kodwa futhi awusizo kakhulu, ngaphandle kwalokho, uma uwabhekisisa, ungabona ukuthi muhle kakhulu.
