Hoʻomohala iʻa: hua manu

iʻa huwvoa

Transparent nā hua o ka iʻa iwi a puni loa. Aia kekahi membrane waho waho me nā pores liʻiliʻi, i kapa ʻia ʻo ka chorion. Maʻalahi ke ʻano o kēia membrane, ʻoiai ma kekahi ʻano he latike hexagonal kona.

El yolk mai ka hua manu ka mea nāna e mālama ka hāʻawi ʻana i ka nā mālama mālama ikehu pono ka embryo i kona wā hoʻomohala a hiki i ka hiki iā ia ke hānai iā ia iho, ke lilo ia i ʻāpana o ka plankton. I kekahi ʻano iʻa, noho ka yolk i nā wahi āpau i loaʻa a waiho wale i kahi wahi manuahi.


En elasmobranchs, ke loaʻa iā lākou ovules i hoʻomomona ʻia, Uhi lākou iā lākou me kahi capsule kornea i loaʻa nā ana a me nā nui ma muli o ka laha. I kekahi mau manō oviparous, no ka laʻana, he ʻano ʻoi aku a liʻiliʻi paha o kēia capsule, a hāʻawi ʻia me nā filament e hoʻopaʻa ma lalo.

No ka nui o nā hua, he loli nui ia, ʻoiai aia ma kahi o 1 mm ke anawaena, a hiki ke pae ma waena o 0,25 a me 7 mm i nā ʻano like ʻole. ʻO ka nui hua manu maikaʻi ʻO ia ka mea e hoʻonui i ka nui o nā hua a me ke ola e hiki mai ana o nā larva a me nā ʻōpio.

ka huamoa benthic ʻo lākou, ma ka laulā, ʻoi aku ka nui ma mua o nā planktonic, me ka nui o ka yolk a me ka liʻiliʻi o ka nui. ʻO ka hoʻomohala ʻana o ka embryo i loko o ka hua manu ʻoi aku ka lōʻihi, a puka ka larva i kahi kūlana kiʻekiʻe, me nā maka pigmented.

Iā hoʻi fecundity i iʻa iʻa pelagic ʻoi aku ke kiʻekiʻe ma mua o ka poʻe e waiho hua ana benthic. Aia kahi pilina maopopo ma waena o ka nui o ka hua a me ke ola larval. A ʻo ka mea ʻoiaʻiʻo hiki i nā larva nui loa ke ʻai i ka laulā o nā mea pio a me nā nui, a i ka manawa like, ʻaʻole i maʻalahi i nā mea ʻino.


Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.

E lilo i mea mua e wehewehe

E waiho i kāu manaʻo

Kāu leka uila aae? E,ʻaʻole e paʻiʻia.
