I- izilwane zasemanzini Ziyizilwane ezinomgogodla, empeleni zazingama-vertebrate okuqala adlula esuka emanzini aya ezweni elikhulu. Isib. iselesele, iselesele, intulo.
Esikhathini esedlule, izilwane eziphila ezweni nasemanzini zazimele iqembu lezilwane elibaluleke kakhulu, ngenxa yenani lezinto eziphilayo ezazikhona nangenxa yobukhulu bomzimba wazo omkhulu. Kodwa-ke, kamuva badluliswa yizilwane ezihuquzelayo, leli qembu lehliselwa ezigabeni ezimbalwa.
Ama-Amphibian alinganiselwa ukuthi avela ezinhlanzini cishe eminyakeni eyizigidi ezingama-360 edlule, nokuthi lezo ezihuquzelayo kamuva zavela kuzo, okwathi kamuva kwaveza izilwane ezincelisayo nezinyoni zanamuhla.
Izibonelo zama-amphibians

Izici ze-Amphibian
Ama-Amphibians ane isikhumba esingenalutho, phefumula ngezinhlungu futhi abanayo imilenze lapho besebancane; lapho sebekhulile baphefumula ngamaphaphu futhi banemilenze emine enolwelwesi oluhlukanisiwe.
Ngaphezu kwalokho, bathola ukuguqulwa komzimba, okusho ukuthi, badlula ezigabeni ezahlukene zokuphila, ikakhulukazi ezintathu:
- Lokho kwe iqanda
- I- isibungu (yokuphefumula kwe-gill)
- I- umuntu omdala (zokuphefumula kwamaphaphu).
Eqinisweni, yiwo kuphela ama-vertebrate okumele aguqulwe.
Ezinye izici:
- Ama-amphibians amadala angahlala emanzini noma emhlabeni (impilo yasemhlabeni), izibungu zingahlala emanzini kuphela.
- Ama-Amphibians aphefumula ngesikhumba (ukuphefumula okunqamulelayo), ukugcina isikhumba simanzi futhi kuvimbele ukukhishwa kwesikhumba, anezindlala azikhipha ngazo isikhwehlela.
- Ziyizilwane zokukhulelwa kwangaphandle noma kwangaphakathi kanye ne-oviparous.
- Azinazo izinwele noma izikali.
- Zondla izinambuzane, izibungu, ama-slugs, nezicabucabu; nemifino noma izilwane ezincelisayo ezincane, kanye nezinhlanzi kanye nezibungu.
- Lapho izinga lokushisa langaphandle liphansi kakhulu, bavame ukuhlala bengenzi lutho, futhi bavame ukusinda ngenxa yenqolobane yamafutha abayiqongelele emzimbeni wabo.
- Lezi yizilwane ezibhidliza ukudla kwazo ngaphandle kokukudiliza phambilini.
- Banesitho somlingiswa, i-cloaca, esebenza njengendawo yokuphuma kuphela enomsebenzi wokuchama nowokuzala.
Ukuhlukaniswa
Kukhona ama-oda amathathu noma amakilasi ama-amphibians:
- I-Gymnophiona noma i-apodes (ngaphandle kwemilenze)
- I-Caudata noma i-caudates (ngomsila)
- I-Anura noma i-anurans (amaxoxo namasele).
Kulinganiselwa ukuthi kukhona ezinye Izinhlobo ezingama-4 300 zama-amphibians eziphila namuhla, kodwa ngendlela eyiqembu lezinto eziphilayo elinabantu abaye bancipha kakhulu isikhathi esithile kule ngxenye, ikakhulukazi ngenxa yokuguqulwa kwendawo yabo yemvelo nokuguquka kwesimo sezulu.
