Emvelweni singabona eziningana amasu okuzala, futhi enye yazo i-oviparity. Kufanele wazi ukuthi kunezilwane eziningi ezilandela isu elifanayo, elivele ngaphambili kakhulu emlandweni wokuziphendukela kwemvelo kunabaphilayo.

uma ufuna ukwazi yiziphi izilwane ezi-oviparous, liyini leli qhinga lokuzala kanye nezinye izibonelo zezilwane ezi-oviparous, qhubeka ufunda le ndatshana yiPeritoAnimal. Uzoxazulula konke ukungabaza kwakho futhi ufunde izinto ezimangalisayo!

yiziphi izilwane ezi-oviparous

Wena izilwane oviparous yilezo lezo amaqanda aqanduselayo, njengoba zingaphandle komzimba kanina. Umanyolo ungaba wangaphandle noma wangaphakathi, kepha ukuqandula kwenzeka njalo endaweni yangaphandle, akukaze kube esibelethweni sikamama.


Wena izinhlanzi, izilwane eziphila ezweni nasemanzini, izilwane ezinwabuzelayo nezinyoni, njengezinye izilwane ezincelisayo ngezikhathi ezithile, ziyi-oviparous. Imvamisa zibekela amaqanda azo ezidlekeni ezivikelwe kahle, lapho umbungu uzokhula khona ngaphakathi kweqanda bese uqanduselwa. ezinye izilwane zikhona umabhebhana, okusho ukuthi, afukamela amaqanda ngaphakathi komzimba esikhundleni sesidleke futhi amaphuphu azalwa ephila ngokuqondile emzimbeni womama. Lokhu kungabonakala kwezinye izinhlobo zoshaka nezinyoka.

THE ukuzalanisa isilwane nge-oviparous kuyisu lokuziphendukela kwemvelo. ingakhiqiza iqanda elilodwa noma amaningi. Iqanda ngalinye liyi-gamete eyenziwe ngezinto zofuzo ezivela kowesifazane (iqanda) nezinto zofuzo ezivela kowesilisa (isidoda). Isidoda kufanele sithole indlela eya eqandeni, kungaba endaweni yangaphakathi (umzimba wowesifazane), lapho ukukhulelwa kungaphakathi, noma endaweni yangaphandle (ngokwesibonelo, indawo yasemanzini), lapho ukukhulelwa kungaphandle.


Uma iqanda nesidoda kuhlangana, sithi iqanda selikhulelisiwe bese liba a umbungu ozokhula ngaphakathi kweqanda. Izilwane eziningi zikhiqiza amaqanda amaningi, kepha abuthakathaka kakhulu, futhi inzuzo yaleli qhinga ukuthi, ngokukhiqiza inzalo eningi kangaka, kunethuba elingcono lokuthi okungenani eyodwa yazo izosinda ezilwaneni ezizingelayo. Ezinye izilwane zikhiqiza amaqanda ambalwa kakhulu, kodwa makhulu kakhulu futhi aqinile futhi lokhu kwandisa amathuba okuthi ukukhula komuntu omusha kuzophela bese kuchanyuselwa, kuphakama umuntu omusha onamandla kakhulu, ozoba namathuba amaningi okubalekela izilwane ezidlayo lapho ezelwe.

Ukuba yi-oviparous nakho kunezinkinga zako. Ngokungafani nezilwane ezi-viviparous ne-ovoviviparous, ezithwala inzalo yazo ngaphakathi kwemizimba yazo, izilwane ezi-oviparous badinga ukuvikela noma ukufihla amaqanda abo ngesikhathi sayo sokukhula ezakhiweni ezibizwa ngokuthi izidleke. Izinyoni zivame ukuhlala emaqandeni azo ukuzigcina zifudumele. Endabeni yezilwane ezingazivikeli ngenkuthalo izidleke zazo, kuhlale kunethuba lokuthi umhlaseli azithole futhi azidle, ngakho-ke kubaluleke kakhulu ukukhetha kahle indawo yesidleke futhi uwafihle kahle amaqanda.


Izilwane ezi-Oviparous neViviparous - Umehluko

THE umehluko omkhulu phakathi kwezilwane ezi-oviparous kanye ne-viviparous ukuthi izilwane ezi-oviparous azikhuli ngaphakathi kukanina, kuyilapho izilwane ezi-viviparous zithola zonke izinhlobo zezinguquko ngaphakathi konina. Ngakho-ke, izilwane ezi-oviparous zizalela amaqanda akhula futhi achamusele intsha. Ngenkathi izilwane ezi-viviparous zizalwa zingabantu abasha abaphilayo futhi azibeki amaqanda.

Izinyoni, izilwane ezihuquzelayo, izilwane eziphila ezweni nasemanzini, izinhlanzi eziningi, izinambuzane, ama-molluscs, ama-arachnids nama-monotremes (izilwane ezincelisayo ezinezici ezihuquzelayo) yizilwane ezi-oviparous. Izilwane eziningi ezincelisayo zingabantu abaphilayo. Ngokugwema ukungabaza, sikhombisa i- uhlu lwezici ehlukanisa i-oviparous ezilwaneni ezi-viviparous:

Okuvuthayo:

  • Izilwane ezi-ovparous zikhiqiza amaqanda akhula futhi achamule ngemuva kokuxoshwa emzimbeni womama;
  • Amaqanda angabekwa esevele efakwe umanyolo noma angavundiswanga;
  • Umanyolo ungaba ngaphakathi noma ngaphandle;
  • Ukukhula kombungu kwenzeka ngaphandle kowesifazane;
  • Umbungu uthola izakhamzimba esikhuphwini seqanda;
  • Amathuba okusinda aphansi.

I-Viviparous:

  • Izilwane ezi-viviparous zizala izilwane eziphilayo, ezikhule ngokugcwele;
  • Azizaleli amaqanda;
  • Ukukhulelwa kweqanda kuhlala kungaphakathi;
  • Ukukhula kombungu kwenzeka ngaphakathi kumama;
  • Amathuba okusinda makhulu.

Izibonelo zezilwane ezi-oviparous

Kunezinhlobo eziningi zezilwane ezizalela amaqanda, ngezansi ezinye zazo:

  • izinyoni: ezinye izinyoni zibeka kuphela iqanda elilodwa noma amabili avundiswa, kanti abanye bafaka amaningi. Ngokuvamile, izinyoni ezizalela iqanda elilodwa noma amabili, njengama-cranes. aziphili isikhathi eside emvelweni. Lezi zinyoni zichitha isikhathi esiningi zinakekela amaphuphu azo ukuzisiza ziphile. Ngakolunye uhlangothi, izinyoni lokho beka amaqanda amaningi, njengama-coots ajwayelekile, anezinga eliphakeme lokusinda, futhi akudingeki ukuthi achithe isikhathi esiningi nezingane zawo.
  • Ama-Amphibians kanye nezilwane ezihuquzelayo: amaselesele, ama-newt kanye nama-salamanders onke angama-amphibian, ahlala ngaphakathi nangaphandle kwamanzi, kepha awadinga ukuthi ahlale emanzi, futhi abeke namaqanda, ngoba la maqanda awanamagobolondo futhi, emoyeni, babezoma ngokushesha. Izilwane ezihuquzelayo, njengezibankwa, izingwenya, izibankwa, izimfudu nezinyoka, zingaphila emhlabathini noma emanzini, futhi zizalela amaqanda ngaphandle noma ngaphakathi kuwo, kuye ngohlobo lwazo. Njengoba zingajwayele ukunakekela izidleke zazo, zizalela amaqanda amaningi ukuze izinga lokusinda lenyuke.
  • Inhlanzi: zonke izinhlanzi zizalela amaqanda emanzini. Izinhlanzi zesifazane zikhipha amaqanda azo phakathi ngokukhululeka, zifake ezitshalweni zasemanzini noma ziwaphonse emgodini omncane ombiwe. Inhlanzi yesilisa bese ikhipha isidoda emaqandeni. Ezinye izinhlanzi, njengama-cichlids, zigcina amaqanda azo emilonyeni yazo ngemuva kokukhulelwa ukuze zivikeleke ezilwaneni ezidla ezinye.
  • ama-arthropods: ama-arachnids amaningi, ama-myriapods, ama-hexapods nama-crustaceans akha iqembu le-arthropod yi-oviparous. Izicabucabu, ama-centipedes, izinkalankala namabhu ngezinye zezigidi ze-arthropods ezizalela amaqanda, futhi bafaka amakhulu abo. Abanye bazalela amaqanda akhuleliswe ngokuvundiswa kwangaphakathi, kanti amanye abeka amaqanda angavundisi asadinga isidoda.

Izibonelo Zezilwane Ezincelisayo Oviparous

Akuvamile kakhulu ukuthi izilwane ezincelisayo zizalele amaqanda. Iqembu elincane kuphela elibizwa ngokuthi yi-monotremate elenza lokho. Leli qembu lifaka phakathi i-platypus nama-echidna. Singabathola kuphela e-Australia nakwezinye izingxenye ze-Afrika. Lezi zidalwa zibeka amaqanda, kepha ngokungafani nezinye izilwane ezi-oviparous, ama-monotremes ondla amaphuphu awo ngobisi futhi anezinwele.
