Izilwane ze-Ovoviviparous: izibonelo kanye nelukuluku - Izifufuzo Ezifuywayo

-Delile

Kulinganiselwa ukuthi emhlabeni kunezinhlobo zezilwane ezingaba yizigidi ezimbili. Abanye, njengezinja noma amakati, singabona cishe nsuku zonke emadolobheni futhi kuningi okwaziwayo ngawo, kepha kunezilwane ezingajwayelekile ezinenqwaba yezifiso esingazazi.

Lokhu kunjalo ngezilwane ezi-ovoviviparous, zinefomu ehluke kakhulu yokuzala futhi zinezici ezingajwayelekile kepha ezithakazelisa kakhulu. Ukuze ufunde kabanzi ngezilwane futhi uthole imininingwane eyigugu ngazo izilwane ovoviviparous, izibonelo kanye nelukuluku, qhubeka ufunde le ndatshana yePeritoAnimal.

Ziyini izilwane ze-ovoviviparous?

Wena izilwane oviparous, njengezinyoni nezilwane ezinwabuzelayo eziningi, zizala ngamaqanda abekwa abesifazane emvelweni (ngenqubo eyaziwa ngokuthi ukubekela) futhi, ngemuva kwesikhathi sokufukamela, la maqanda ayaqhuma, avelise inzalo futhi aqale impilo entsha ngaphandle.


I-US izilwane eziphilayo, iningi yizilwane ezincelisayo njengezinja noma abantu, imibungu iyakhula ngaphakathi kwesibeletho sikamama, ifinyelela ngaphandle ngokuzala.

Okungukuthi, i- izilwane zeqanda-viviparous zikhula emaqandeni atholakala emzimbeni womama. La maqanda aphuka ngaphakathi emzimbeni womama futhi ngesikhathi sokuzalwa amantombazane azalwa, ngokushesha noma ngemuva nje kokuba iqanda liphukile.

Impela, wake wezwa umbuzo: ngubani owafika kuqala, inkukhu noma iqanda? Ukube inkukhu bekuyisilwane se-ovoviviparous, impendulo ibingaba lula, okungukuthi, zombili ngasikhathi sinye. Okulandelayo, sizokwenza uhlu nge izibonelo zezilwane ezi-ovoviviparous Ngifuna ukwazi kakhulu.

Ulwandle

I-seahorse (I-Hippocampus) kuyisibonelo sesilwane esinesifiso sokufuna ukwazi se-ovoviviparous, njengoba zizalwa ngamaqanda afukamele ngaphakathi kukababa. Ngesikhathi sokukhulelwa, ulwandle lwensikazi ludlulisela amaqanda emadodeni, awagcina evikelekile esikhwameni lapho, ngemuva kwesikhathi esithile sokukhula, aphule futhi inzalo iphume.


Kepha akusilona lodwa ilukuluku mayelana ne- Amahhashi olwandle kodwa futhi, ngokungafani nalokho abantu abaningi abakucabangayo, akuzona ama-crustaceans, njengezimfanzi nama-lobster, kodwa inhlanzi. Esinye isici esithandekayo ukuthi zingashintsha umbala ukudida izilwane ezizungezile.

I-Platypus

I-platypus (I-Ornithorhynchus anatinus) uvela e-Australia nasezindaweni eziseduze, kubhekwa njengesinye sezilwane eziyinqaba emhlabeni, ngoba yize iyisilwane esincelisayo sinomlomo ofana nedada nezinyawo zezinhlanzi, ezilungiselelwe impilo yasemanzini. Eqinisweni, kuthiwa abaseNtshonalanga bokuqala ababona lesi silwane babecabanga ukuthi kwakuyihlaya nokuthi othile wayezama ukubakhohlisa ngokubeka uqhwaku ku-beaver noma esinye isilwane esifanayo.


Ubuye abe nesibungu seqakala esinobuthi, ekubeni esinye sezilwane ezincelisayo ezinobuthi ezimbalwa ezikhona. Noma kunjalo, yize ekhonjwe kaningi njengesinye sezibonelo zezilwane ezi-ovoviviparous, iplatypus izalela amaqanda kepha ayiqedi ngokushesha ngemuva kokubeka.

Yize kwenzeka esikhathini esifushane (cishe amasonto amabili), isikhathi lapho umama efukamela khona amaqanda esidlekeni. Lapho lishiya iqanda, imidlwane iphuza ubisi olukhiqizwe ngumama.

Funda kabanzi nge-platypus kulesi sihloko se-PeritoAnimal.

inyoka yezinyoka

THE inyoka yezinyoka (I-Viper aspis), esinye isibonelo sezilwane ezi-ovoviviparous kanye nezinyoka eziningi. Lesi silwane esihuquzelayo sitholakala ezingxenyeni eziningi zeMedithera Yurophu, yize singesinolaka kubantu futhi singatholakali kalula, le nyoka. inobuthi obukhulu.

Ukuzwa igama lenyoka ye-asp nakanjani kuyakhumbula indaba ka UCleopatra. Wazibulala lapho ekhashelwa yinyoka ebukhali eyayifihlwe kubhasikidi wamakhiwane. Noma kunjalo, uCleopatra washonela eGibhithe, indawo lapho lesi silwanyana esingenakutholakala kalula khona, ngakho-ke kungenzeka ukuthi sasibhekisela enyokeni yaseGibhithe, eyaziwa nangokuthi i-Asp kaCleopatra, ogama layo ngokwesayensi Naja heje.

Kunoma ikuphi, izazi-mlando eziningi zikuthatha njengamanga ukuthi ukufa kubangelwe ukulunywa yinyoka, noma ngabe hlobo luni lwayo, bathi uCleopatra kungenzeka azibulale esebenzisa uhlobo oluthile lobuthi, yize indaba yenyoka inentelezi ethe xaxa.

i-lycrane

I-lynchan (Ama-Anguis fragilis), ngaphandle kwesithunzi sokungabaza, isilwane esimangalisa ngempela. Ngaphezu kokuba yi-ovoviviparous, kuyi- isibankwa esingenamlenze. Ibukeka njengenyoka kepha, ngokungafani nezilwane ezihuquzelayo, ayihlali ifuna ilanga njengoba ithanda izindawo ezimanzi nezimnyama.

Ngokungafani ne-platypus ne-asp, i itshe lokhiye alinabo ubuthi yize kunamahemuhemu okuphikisana nalokho. Eqinisweni, akunangozi enkulu lapho izibungu ziwumthombo oyinhloko wamandla. Kukhona nalabo abathi i-lyranço iyimpumputhe, kepha akukho ukuthembeka kulolo lwazi.

Ushaka omhlophe

Kunoshaka abaningi abangaba yizibonelo zezilwane ezi-ovoviviparous, ezifana noshaka omhlophe (Carcharodon carcharias), edumile futhi esatshwayo emhlabeni wonke ngenxa ye-movie "Imihlathi" eqondiswa nguSteven Spilberg. Kodwa-ke, empeleni, isihloko sokuqala se-movie sithi "Imihlathi" okusho ngesiPutukezi okusho "imihlathi"

Yize eyisidlakela esikwazi ukushwabadela umuntu kalula, ushaka omhlophe uncamela ukuzondla ngezinye izilwane, njengezimvu zamanzi. Ukufa kwabantu okubangelwa yilesi silwane kuphansi kunalokho okubangelwa ezinye izilwane ezibonakala zingenabungozi kangako emehlweni, njengezimvubu.
