Umxholo
Inkqubo ye- izilwanyana zasemanzini Zizilwanyana ezinomqolo, enyanisweni zazizizilwanyana zokuqala zomqolo wokugqibela ezisuka emanzini zisiya kwilizwekazi. Umz. isele, isele, intulo.
Kwixesha elidlulileyo, izilwanyana zasemanzini zazimele iqela lezilwanyana elibaluleke kakhulu, zombini ngenxa yenani lezinto ezazikho nangenxa yobukhulu bomzimba wazo. Nangona kunjalo, kamva bavela ngendaleko zizirhubuluzi, eli qela lancitshiswa laya kwiindidi ezimbalwa.
Ama-Amphibian aqikelelwa ukuba avela kwiintlanzi Malunga neminyaka engama-360 ezigidi eyadlulayo, kwaye ezo zirhubuluzi kamva zavela kuzo, ezathi emva koko zavelisa izilwanyana kunye neentaka zanamhlanje.
Imizekelo yee-amphibians
- Iphedi eqhelekileyo
- Toad enkulu
- Intulo
- Triton
- Isele elinetyhefu
- Isele laseNew Zealand
- Isele laseSeychelles
- Isele lomthi
- Utolo oluhlaza isele
- I-Axolotl okanye i-ajolote (i-salamander yaseMexico)
- UCecilia
- I-Pygmy flatfoot salamander
- Inewt jalapa engeyonyani
Iimpawu zeAmphibian
Ama-Amphibians ane isikhumba esingenanto, phefumla ngee-gill kwaye abanamilenze xa besebancinci; xa sele bebadala bayaphefumla ngemiphunga kwaye banemilenze emine enembumba yamacandelo ahlukeneyo.
Ukongeza, bajongana nenguquko, oko kukuthi, badlula kwizigaba ezahlukeneyo zobomi, ikakhulu ezintathu:
- Oko kwe iqanda
- Inkqubo ye- umbungu (yokuphefumla kwegill)
- Inkqubo ye- umntu omdala (Ukuphefumla kwemiphunga).
Ngapha koko, zezona zilwanyana zomqolo ezizezinye zokufumana uguquko.
Ezinye zeempawu:
- Abantu abadala abahlala emanzini nasemanzini bangahlala emanzini okanye emhlabeni (ubomi obuphakathi komhlaba), imibungu inokuhlala emanzini kuphela.
- Ama-Amphibians aphefumla ngesikhumba (ukuphefumla okunqamlezileyo), ukugcina ulusu lufumile kwaye kuthintele ukususwa, banamadlala abangela ngawo ukukhupha intsholongwane.
- Zizilwanyana zokuchumisa kwangaphandle okanye ngaphakathi kunye ne-oviparous.
- Azinaboya neenwele.
- Batya izinambuzane, iintshulube, iislugs, kunye nezigcawu. nayo imifuno okanye izilwanyana ezincancisayo ezincinci, kunye nentlanzi kunye nemibungu.
- Xa ubushushu bangaphandle buphantsi kakhulu, bahlala bengenzi nto, kwaye bahlala bephila ngenxa yolondolozo lwamafutha abalufumene emzimbeni wabo.
- Ezi zizilwanyana ezihambisa ukutya kwazo ngaphandle kokophula ngaphambili.
- Banelungu lophawu, i-cloaca, esebenza njengekuphela kwendawo yokuphuma enomsebenzi wokuchama kunye nokuzala.
Ukwahlulahlula
Kukho iiodolo ezintathu okanye iiklasi ze-amphibians:
- I-Gymnophiona okanye i-apodes (ngaphandle kwemilenze)
- I-Caudata okanye i-caudates (ngomsila)
- Anura okanye anurans (amasele kunye neetads).
Kuqikelelwa ukuba kukho ezinye Iindidi ezingama-4 300 zama-amphibians ezihlala namhlanje, kodwa ngendlela liqela lebhayoloji elinabantu bayo behle kakhulu okwexeshana kule nxalenye, ikakhulu ngenxa yotshintsho lwendalo kunye nokutshintsha kwemozulu.
