• Nā laʻana o nā holoholona ovoviviparous

ʻO ka holoholona ovoviviparous ʻo ia nā mea e hoʻomohala i loko o ka hua manu ma mua o ka hānau ʻana. Akā ʻo ka mea e hoʻokaʻawale ai ka ovoviviparous ʻo ia ka hua manu i loko o ka makuahine a hiki i ka hoʻomohala piha ʻana o ka embryo. ʻO kēia ke kumu i puka mai ai ka holoholona mai ka hua manu ma hope koke o ka waiho ʻia ʻana o ka hua. Hiki iā ia ke pa mai i ka hua i loko o ke kino o ka makuahine a hānau ma hope.

He mea nui e hoʻokaʻawale i nā holoholona ovoviviparous mai nā holoholona ʻē aʻe e hoʻomohala pū i kā lākou mau embryos ma loko o nā hua, ka oviparous. Hoʻokomo ka hope i kā lākou mau hua i loko o ka wahi i waho i ka hoʻomaka o ka ulu ʻana o ka embryonic. I nā huaʻōlelo ʻē aʻe, hoʻomohala nā embryos ma waho o ke kino o ka makuahine.

Hoʻokaʻawale pū ʻia lākou holoholona holoholona, ʻo ia nā mea e ulu aʻe ka embryo i loko o ke kino o ka makuahine, e like me nā mea momona. ʻOiai hoʻomohala pū ka viviparous i ka embryo i loko, ʻo ka ʻokoʻa ʻoiai uhi ʻia e ka pūpū, ʻaʻole hiki ke hānai pololei ʻia e ka makuahine.

ʻO ia ka mea:

• ʻO ke kiko maʻamau ma waena o ovoviviparous a me oviparous: pale ʻia ka embryo e kahi pūpū.
• Kahi maʻa mau ma waena o ovoviviparous a me viviparous: Loaʻa ka hoʻomomona ma waena o ke kino o ka makuahine, kahi e ulu ai ka embryo.

Nā laʻana o nā holoholona ovoviviparous

1. Mano keʻokeʻo: He ʻano manō nui a ikaika. He waha piʻo kona. Pono e ʻauʻau mau (ʻaʻole hiki ke noho mālie) i mea e hanu ai a lana, no ka mea ʻaʻohe ona ʻau ʻauʻau. ʻAi nā embryos ma o ka yolk. ʻAʻole moe kēia hua manō akā ua pā ka ʻōpio i loko o ka makuahine a hānau ʻia hoʻomohala ʻia.
2. ʻO Boa constrictor: Reptilia hiki ke ana ma waena o 0.5 a me 4 mau mika, ke kaukaʻi ʻia i nā subspecies. Eia kekahi, ʻoi aku ka nui o nā wahine ma mua o nā kāne. He ʻulaʻula a keʻokeʻo, a ʻulaʻula a ʻulaʻula hoʻi, me nā ʻano ʻokoʻa e like me nā mea kau. He hoa i ka wā ua. Noho kāna hana i mau mahina. Loaʻa ka hatching o nā hua i loko o ke kino o ka makuahine, hatching ua hoʻomohala i nā keiki.
3. Mānini: Ke ʻano o ka manō liʻiliʻi, a ʻoi aku i kahi mika o ka lōʻihi. Hoʻohālikelike ʻia e ka loaʻa ʻana o nā spine ʻawahia ma luna o ke kino. ʻO ia ka nui o ka nui o ka manō akā me ka ʻāpana o ka hoʻokaʻawale ʻana. Aia ka litter reproductive i ka nui o ka wahine, ʻo ka mea maʻamau ʻo 1 a 20 embryos no kēlā me kēia hana, akā hiki i nā wahine nui ke loaʻa nā litters he nui aku. Hānau ʻia lākou i waho o ka hua manu.
4. ʻO Stingray (pilikua nui): Hoʻokaʻawale ʻia ia mai nā ʻano ʻē aʻe no ka mea ʻaʻohe ona lāʻau ʻawaʻawa ma kona huelo. Eia kekahi ma muli o kona nui nui. Noho i ke kai kūʻono. Hiki iā ia ke lele i waho o ka wai. I ka manawa o ka hānau hou ʻana, he ʻaha kāne kekahi wahine wahine. I mea e hele aku ai kekahi o lākou i ka kope, pono iā ia e pepehi i kāna mau mea hoʻokūkū. Ua manaʻo ʻia ʻo ka manawa e waiho ai nā hua i loko o ka wahine hiki ke ʻoi aku ma mua o ʻumikūmālua mau mahina. Hoʻokahi a ʻelua paha ʻōpio o lākou i ka ʻōpala.
5. Anaconda: He genus o ka nahesa constrictor. Hiki iā ia ke ana i ʻumi mau mika ka lōʻihi. ʻOiai ʻaʻole ia e noho i kahi hui akā i kahi ala kaʻawale, ke makemake ka wahine e hānau hou hiki ke ʻumeʻume i ke kāne ma ka hoʻokuʻu ʻana i nā pheromones. I kēlā me kēia ʻōpala ma waena o 20 a 40 mau ʻōpio i hānau ʻia, ma kahi o 60 cm ka lōʻihi.
6. Toad Suriname: Amphibian e noho ana i nā wahi tropical a subtropical. Hoʻohālikelike ʻia e kona kino pālahalaha a me kona poʻo pālahalaha, triangular. Uhi ʻeleʻele iki kona kala. He ʻano kūikawā ʻo ia o ka holoholona ovoviviparous, ʻoiai ka hoʻohua ʻana ma waho o ke kino o ka makuahine. I ka manawa e momona, hoʻopili hou ka wahine i nā hua i kona kino. ʻAʻole like me nā amphibians ʻē aʻe, i hānau ʻia ma ke ʻano he larvae a laila hele i ka metamorphosis, lawe kēia toad i kāna ulu ulu i loko o ka hua manu, a ʻo nā poʻe i hānau ʻia ua loaʻa ko lākou ʻano hope loa.
7. Platypus: Ua manaʻo ʻia he mammal ia, akā waiho i nā hua, no laila hiki ke hoʻohālikelike ʻia me ovoviviparous. He holoholona semi-aquatic ia e noho ana ma ka hikina o Australia a ma Tasmania. Hoʻohālikelike ʻia e kona hiʻohiʻona kikoʻī, me kahi ihu e like me ka nuku o ka ʻāʻī, kahi huelo e like me ka beaver, a me nā wāwae like me ka otter. He mea ʻawahia.
8. ʻO Jackson Trioceros: Nāʻano o ka chameleon ovoviviparous. ʻEkolu ona pepeiaohao, no laila i kapa ʻia ʻo ia ʻo "trioceros". Noho ma ʻApelika Hikina. Hānau ʻia ka ʻōpio i nā litters ma waena o 8 a 30 mau kope, me kahi ʻano o ʻeono mau mahina.
9. Hipopotamu (seahorse): ʻO ia kahi ʻano ovoviviparous, ʻoiai ʻaʻole oʻo nā hua i loko o ke kino o ka wahine akā i ke kino o ke kāne. Kū ka mea hoʻomomona i ka wā e hele ai ka wahine i nā hua i loko o ka ʻeke a ke kāne. Ua like ka ʻeke me ka marsupial, ʻo ia hoʻi ia ma waho a me ka ventral.
10. Lution (Crystal shingles): holoholona loa, no ka mea, he moʻo wāwae ʻole ia. ʻO ia ka mea i ka nānā aku ua like ia me ka nahesa. Eia nō naʻe, ʻike ʻia he moʻo no ka mea aia nā kino o kona iwi i kona kino i loaʻa nā ʻano o nā moʻo. Eia kekahi, he mau lihilihi hoʻoneʻe, ʻaʻole like me nā nahesa. He kolo ʻo ia e noho ana i ʻEulopa a hiki ke ana i 40 cm, a i ʻole 50 cm i nā wahine. Hana ka hana hou i ka puna. Ma hope o 3 a 5 mau mahina o ka hāpai ʻana, hoʻomoe ka wahine i nā hua me nā ʻōpio makua o loko, a kū koke ka hatching.
