ʻO ka iʻa, a me nā holoholona terrestrial a i ʻole nā mammal wai wai, pono e hopu i ka oxygen e ola, ʻo ia kekahi o kā lākou hana nui. Eia nō naʻe, ʻaʻole i loaʻa i ka iʻa ka oxygen mai ka lewa, hiki iā lākou ke hopu i ka oxygen i hoʻoheheʻe ʻia i loko o ka wai ma o kahi lālā i kapa ʻia ʻo brachia.
Makemake e ʻike hou aʻe e pili ana pehea ka hanu o ka iʻa? I kēia ʻatikala na PeritoAnimal e wehewehe mākou pehea ka ʻōnaehana hanu o ka iʻa teleost a pehea e hana ai kā lākou hanu. E hoʻomau i ka heluhelu!
Pehea ka hanu o ka iʻa i ka oxygen i loko o ka wai
Ma brachia o nā iʻa teleost, ʻo ia ka hapa nui o nā iʻa me ke koe ʻole o ka manō, nā kukuna, nā ipukukui a me nā hagfish, i loaʻa. ma nā ʻaoʻao ʻelua o ke poʻo. Hiki iā ʻoe ke ʻike i ka lua opercular, ʻo ia ka ʻāpana o ka "alo iʻa" e wehe i waho a kapa ʻia ʻo ka operculum. Ma loko o kēlā me kēia lua opercular ka brachia.
Kākoʻo ʻia ka brachia e ʻehā nā kūpeʻe brachial. Mai kēlā me kēia arch brachial, aia ʻelua mau hui filament i kapa ʻia nā filament brachial i loaʻa ke ʻano "V" e pili ana i ka pio. Pālua kēlā me kēia filament me ka filament kokoke, e hana ana i kahi tangle. Ma ka ʻaoʻao aʻe, kēia mau mea nā filament brachial Loaʻa iā lākou kā lākou mau wanaʻao i kapa ʻia ʻo lamellae lua. Ma aneʻi e kūkaʻi kahi ʻaukā, hopu ka iʻa i oxygen a hoʻokuʻu i ke kalapona kalapona.
Lawe ka iʻa i ka wai kai ma o ka waha a, ma o ke kaʻina hana paʻakikī, hoʻokuʻu i ka wai ma o ka operculum, e hele ma waena o ka lamellae, ma hea ia hopu i ka oxygen.
ʻōnaehana hanu iʻa
ʻ ʻōnaehana hanu iʻa loaʻa iā ia ka inoa o ka paipu oro-opercular. ʻO ka pauma mua, ka buccal, hoʻokomo i ka pihi maikaʻi, e hoʻouna ana i ka wai i ka lua opercular a, a ʻo ka lua, ma o ke kaomi maikaʻi ʻole, e omo i ka wai mai ka waha o ka waha. I ka pōkole, pahu ka waha waha i ka wai i loko o ka lua opercular a hānai kēia iā ia.
I ka manawa o ka hanu, hāmama ka iʻa i kona waha a me ka ʻāina kahi e hoʻohaʻahaʻa ʻia ai ke alelo, e hoʻonui i ka wai e komo i loko no ka mea ua emi ke kaomi a komo ka wai kai i loko o ka waha no ka gradient. Ma hope, pani ʻo ia i ka waha e hoʻonui ana i ke kaomi a hoʻohele i ka wai ma loko o ka lua opercular, kahi e haʻahaʻa ai ke kaomi.
A laila, ʻaelike ka lua opercular, e koi ana i ka wai e hele ma waena o ka brachia kahi o ka kuapo kinoea a waiho passively ma o ka operculum. Ke wehe hou i kona waha, hoʻopuka ka iʻa i kahi hoʻi o ka wai.
E aʻo pehea e hoʻohua ai ka iʻa i kēia ʻatikala PeritoAnimal.
Pehea ka hanu o ka iʻa, he mumū ko lākou?
Me ke ʻano he contradictory paha, ua alakaʻi ka evolution i ka hiʻona o ka iʻa māmā. Ma loko o ka filogeny, hoʻokaʻawale ʻia lākou i ka papa ʻO Sarcopterygii, no ka lobed fin. Manaʻo ʻia pili kēia mau lungfishes i kēlā mau iʻa mua i hāpai i nā holoholona terrestrial. ʻEono wale nō iʻa i ʻike ʻia me nā akemāmā, a ʻike wale mākou e pili ana i ke kūlana mālama o kekahi o lākou. ʻAʻohe inoa ʻē aʻe o kekahi.
Ma ʻano iʻa me ka ake māmā he:
- Piramboia (Lepidosiren paradox);
- ʻO ka lungfish ʻApelika (Protopterus annectens);
- Protopterus amphibius;
- Protopterus dolloi;
- Pahu lung Australia.
ʻOiai hiki ke hanu i ka ea, pili loa kēia mau iʻa i ka wai, ʻoiai ke loaʻa ʻole ma muli o ka maloʻo, peʻe lākou ma lalo o ka lepo, e pale ana i ke kino me kahi papa o nā mucus hiki iā lākou ke hana. Maʻalahi loa ka ʻili i ka make wai, no laila me ka ʻole o kēia hoʻolālā e make lākou.
E ʻike i ka iʻa e hanu mai ka wai i kēia ʻatikala na PeritoAnimal.
Hiamoe ka iʻa: wehewehe
ʻO kekahi nīnau e hāpai ana i nā kānalua i waena o ka poʻe inā hiamoe ka iʻa, ʻoiai ke hāmama mau ko lākou mau maka. He kuleana ko ka iʻa no ka ʻae ʻana i kahi holoholona e hiamoe, no laila hiki iā mākou ke ʻōlelo he hiki i kahi iʻa ke hiamoe. Eia naʻe, ʻaʻole maʻalahi e hoʻomaopopo ke hiamoe kahi iʻa no ka mea, ʻaʻole moakaka nā hōʻailona e like me, e ʻōlelo, i ka māmele. ʻO kekahi o nā hōʻailona maopopo loa e hiamoe ana kahi iʻa e hoʻolōʻihi ʻia i ka hana ʻole. Inā makemake ʻoe e ʻike i ka ʻike hou e pili ana pehea a pehea e hiamoe ai ka iʻa, e nānā i kēia ʻatikala PeritoAnimal.
Inā makemake ʻoe e heluhelu hou aku i nā ʻatikala e like me Pehea ka hanu ʻana o ka iʻa: wehewehe a me nā laʻana, Paipai mākou iā ʻoe e komo i kā mākou Curiosities ʻāpana o ka honua holoholona.
