Viviparity ndi mawonekedwe oberekera zomwe zimapezeka m'zinyama zambiri, kuphatikiza pa zokwawa zina, nsomba ndi amphibiya. Viviparous nyama ndi nyama zomwe zimabadwa kuchokera m'mimba mwa amayi awo. Anthu, mwachitsanzo, amakhala okhazikika.

Mkazi akakwatirana kapena atagonana ndi wamwamuna wamtundu womwewo, chamoyo chatsopano chimatha kupangidwa, chomwe chimatha kumapeto kwa nthawi yoyembekezera, chikhala cholowa cha makolo ake.

Pitirizani kuwerenga nkhani iyi ya PeritoAnimal yomwe tidzafotokozere mwatsatanetsatane Viviparous Animals - Zitsanzo ndi Makhalidwe. Kuwerenga bwino.

Kodi amoyo ndi otani

Viviparous nyama ndi omwe amachita zawo Kukula kwa mluza mchiberekero cha kholo, kulandira kudzera mwa iwo mpweya wofunikira ndi michere kufikira nthawi yobadwa, pomwe zimawonedwa ngati zopangidwa mokwanira ndikukula. Chifukwa chake, titha kunena kuti ndi nyama zomwe zimabadwa m'mimba mwa amayi, osati mazira, zomwe ndi nyama za oviparous.

Kukula kwa mazira m'minyama

Kuti mumvetsetse bwino kuti nyama zamoyo ndi ziti, ndikofunikira kukambirana za kukula kwa kamwana, kamene kamakhala kuyambira nthawi yopanga umuna mpaka kubadwa kwa munthu watsopano. Chifukwa chake, pakuberekana kwanyama, titha kusiyanitsa mitundu itatu yakukula:

• Nyama zamoyo: pambuyo pa umuna wamkati, mazira amakula m'thupi la kholo, lomwe limateteza ndikuwadyetsa kufikira atakhazikika mokwanira ndikukonzekera kubereka.
• Nyama zowoneka bwino: pamenepa, umuna wamkati umachitikanso, komabe, kukula kwa mluza kumachitika kunja kwa thupi la mayi, mkati mwa dzira.
• Ovoviviparous nyama: komanso kudzera mu umuna wamkati, mazira a nyama zoperewera amakula mkati mwa dzira, ngakhale pamenepa dzira limakhalanso mumthupi la kholo, mpaka kutuluka kumachitika, chifukwa chake kubadwa kwa mwanayo.

Mitundu yoberekera kwa amoyo

Kuphatikiza pakusiyanitsa mitundu yosiyanasiyana ya kukula kwa miluza, tiyenera kudziwa kuti pali mitundu yobereketsa pakati pa omwe amakhala ndi moyo:

• Chiwindi placental nyama: ndi omwe amakula mkati mwa nsengwa, chiwalo cholumikizidwa muchiberekero chomwe chimafikira panthawi yoyembekezera kuti apange mpata wa mwana wosabadwa. Chitsanzo chingakhale munthu wokhalapo.
• Vuto lokhala ndi Marsupial: mosiyana ndi nyama zina zakutchire, nyama zam'madzi zimabadwa zopanda chitukuko ndipo zimatha kupanga mkati mwa marsupium, thumba lakunja lomwe limakwaniritsa ntchito yofanana ndi nsengwa. Chitsanzo chodziwika bwino kwambiri cha nyama yotchedwa marsupial viviparous ndiyo kangaroo.
• Ovoviviparous: Ndikusakanikirana pakati pa viviparism ndi oviparism. Zikatere, mayi amayikira mazira mkati mwa thupi lake, momwe amakula mpaka atakhazikika. Achinyamata akhoza kubadwira m'mimba mwa mayi kapena kunja kwake.

Makhalidwe a omwe amakhala ndi moyo

1. Mchitidwe wa mimba

Nyama za viviparous zimasiyana ndi nyama zomwe zimayikira mazira "akunja", monga mbalame zambiri ndi zokwawa. Nyama za Viviparous zimakhala ndi njira yolerera yosinthira kwambiri kuposa nyama zowuma, zotchedwa placental viviparism, ndiye kuti, nyama zomwe mwana wawo amakhala omaliza thumba "placenta" mkati mwa mayi mpaka mayi atakhwima, wamkulu komanso wamphamvu mokwanira kuti abadwe ndikudzipulumutsira panokha kunja kwa thupi.

2. Placenta

Chinthu china chofunikira ndikuti kukulitsa nyama zosavomerezeka kulibe chipolopolo chakunja cholimba. Placenta ndi chiwalo cholumikizira chomwe chimakhala ndi magazi ochulukirapo komanso amphamvu ozungulira chiberekero cha akazi apakati. Mwana wosabadwayo amadyetsedwa kudzera mu mzere wopezeka wotchedwa chingwe cha umbilical. Nthawi yapakati pa ubwamuna ndi kubadwa kwa viviparous imatchedwa kuti nthawi ya bere kapena nthawi yobereka ndipo imasiyanasiyana kutengera mtunduwo.

3. Kusintha kwa thupi

Chimodzi mwazinthu zofunikira kwambiri pakati pa nyama zakutchire monga nyama zonyamula ndikusintha kofunikira komwe akazi amakumana nako dzira litakwera, komwe nthawi ya bere kapena mimba imayamba. Pakadali pano, chiberekero chimakula kukula molingana ndi kukula kwa zygote, ndipo chachikazi chimayamba kukumana ndi zosintha zamkati ndi zakunja pokonzekera mwachilengedwe kwa ntchito yonseyi.

4. Ana anayi

Nyama zambiri za viviparous ndizapadera zinayi, izi zikutanthauza kuti amafunika miyendo inayi kuyimirira, kuyenda ndikuyenda mozungulira.

5. Chibadwa cha amayi

Amayi ambiri pakati pa zinyama ali ndi mphamvu, yopapatiza Chibadwa cha amayi kudyetsa ndi kuteteza ana awo mpaka atha kukhala ndi moyo pawokha. Mkazi azidziwa nthawi yomwe idzachitike.

6. Anthu oyenda panyanja

M'nyama mulinso mtundu wina wa viviparism, uwu kukhala wocheperako. Tikulankhula za ma marsupial, monga kangaroo.Ma Marsupial ndi zolengedwa zomwe zimabereka ana awo ali osakhwima kenako ndikulandila anawo m'matumba omwe ali nawo m'mimba momwe amawayamwitsa. Anawo amakhalabe m'malo ano mpaka atakhazikika mokwanira ndipo safunikiranso mkaka kuchokera kwa amayi awo kuti akhale ndi moyo.

Zitsanzo za Viviparous Animals - Viviparous Mammals

Tsopano popeza mukudziwa zomwe nyama za viviparous zili, tikunena kuti pafupifupi nyama zonse zamtunduwu ndi za viviparous. Pali zochepa zochepa kupatula zolengedwa zoyamwitsa oviparous, zotchedwa monotremes, omwe nthumwi zawo zazikulu ndi echidna ndi platypus.

Zitsanzo za nyama zonyamula zouma - nsomba zoweta

Zina mwazinsomba zodziwika bwino kwambiri za viviparous - ngakhale zili choncho ndi nyama za ovoviviparous - pali mitundu ya ana agalu, ma platys kapena molineses:

Zitsanzo za Viviparous Animals - Viviparous Amphibians

Monga m'mbuyomu, fayilo ya amakhala amphibians sizodziwika kwenikweni, koma timapeza nyama ziwiri zoyimira mu dongosolo la Caudata:

• merman
• Zamatsenga

Tsopano popeza mukudziwa omwe amakhala ndi moyo komanso mukudziwa zomwe akuchita, mutha kukhala ndi chidwi ndi nkhani ina yokhudza kusinthana kwanyama.

Ngati mukufuna kuwerenga zina zambiri zofanana ndi Nyama Zamoyo - Zitsanzo ndi Makhalidwe, tikukulimbikitsani kuti mulowe mu gawo lathu la Curiosities la nyama.
