ʻO ʻoe iʻa lung hana i kahi hui iʻa laha ʻole mua loa, ka mea hiki ke hanu i ka ea. Noho nā ʻano mea ola āpau i kēia pūʻulu i ka hemisphere hema o ka honua, a ma ke ʻano he holoholona wai, hoʻoholo paʻa loa ko lākou kālaolaola i kēia ala.

I loko o kēia ʻatikala na PeritoAnimal, e hele mākou i ka honua o ka lungfish, pehea lākou e like ai, pehea lākou e hanu ai, a ʻike mākou i kekahi laʻana o nā laha o nā iʻa māmā a me ko lākou ʻano.

He aha nā iʻa māmā

ʻO ʻoe dipnoic a i ʻole lungfish he hui iʻa no ka papa sarkopterygii, i loko o ka iʻa i loaʻa lobed a i ʻole nā ​​ʻiʻo kikokiko.

ʻO ka pilina ʻauhau o ka lungfish me nā iʻa ʻē aʻe e hoʻoulu ai i ka hoʻopaʻapaʻa a me ka paio ma waena o nā kānaka noiʻi. Inā, e like me ka mea i manaʻoʻiʻo ʻia, pololei ka hoʻonohonoho ʻana o kēia manawa, pono pili loa kēia mau holoholona i ka hui o nā holoholona (Tetrapodomorpha) nāna i hāpai i ka nā tetebrod i kēia manawa.

ʻike ʻia i kēia manawa ʻeono ʻano o ka lungfish, hui ʻia i ʻohana ʻelua, lepidosirenidae a me Ceratodontidae. Hoʻonohonoho ʻia ʻo Lepidosirenids i ʻelua hanauna, Protopterus, ma ʻApelika, me ʻehā mau ʻano ola, a me ka lāhui Lepidosiren ma ʻAmelika Hema, me hoʻokahi ʻano. He ʻohana wale nō ka ʻohana Cerantodontidae, ma Australia, Neoceratodusfosteri, ʻo ia ka iʻa māmā ola mua loa.

Iʻa lung: nā ʻano

E like me kā mākou i ʻōlelo ai, loaʻa i ka lungfish palepaʻi lobe, a ʻaʻohe like me nā iʻa ʻē aʻe, hiki i ka iwi kuamoʻo i ka hopena o ke kino, kahi e hoʻomōhala ai i ʻelua mau ʻili ʻili e like me nā lāki.

Loaʻa iā lākou ʻelua māmā māmā hana e like me nā mākua. Loaʻa kēia mau mea mai ka paia ventral ma ka hopena o ka pharynx. Ma waho aʻe o ka hanu, loaʻa iā lākou nā gills, akā lawe wale lākou i 2% o ka hanu ʻana o ka holoholona makua. I ka wā o ka pae larval, hanu kēia mau iʻa i kā lākou gills.

Loaʻa iā lākou nā luaihu, akā ʻaʻole lākou e hoʻohana iā lākou e kiʻi i ka ea, ma kahi o lākou he ʻoihana hanaʻoliva. Uhi ʻia kona kino me nā unahi liʻiliʻi liʻiliʻi i paʻa i ka ʻili.

Noho kēia iʻa i wai papakū a, i ke kau maloʻo, hāliu lākou i loko o ka pālolo, komo i kahi ʻano hibernationa i ʻole ka palaualelo. Uhi lākou i ko lākou waha me ka "uhi" pālolo i loaʻa kahi puka liʻiliʻi e komo ai ka ea e pono ai no ka hanu ʻana. He mau holoholona oviparo lākou, a ʻo ke kāne ke kuleana o ka mālama pono ʻana i nā keiki.

Iʻa lepa: hanu

Loaʻa nā iʻa lung ʻelua mau māmā a hiʻohiʻona i kahi ʻōnaehana puni me nā kaapuni ʻelua. ʻO kēia mau māmā i nui loa nā kualono a me nā pākana e hoʻonui ai i ka ʻenekini kuapo, a ua vascularized nui ʻia lākou.

E hanu ai, kēia iʻa e piʻi i luna, e wehe ana i ka waha a hoʻonui i ka lua o ka waha, e koi ana i ka ea e komo. A laila pani lākou i ko lākou waha, kaomi i ka lua o ka waha, a hele ka ea i loko o ka lua lung mua loa. ʻOiai ka waha a me ka lua o mua o ka akemā e paʻa mau ana, ua ʻaelike ka lua o hope a hoʻoulu i ka ea i hoʻoulu ʻia e ka hanu mua, e hoʻokuʻu ana i kēia ea ma o ka operasela (kahi e loaʻa mau ai nā gills i nā iʻa hanu wai). I ka manawa i hemo ai ka lewa, aelike a wehe ka lumi mua, e ʻae i ka ea i ke keena hope, kahi o ka kuapo kinoea. A laila, ʻike i ka iʻa lung, nā laʻana a me ka wehewehe o ka laha kaulana loa.

Piramboia

ʻO ka Pyramid (ʻO Lepidosiren paradox) ʻo ia kekahi o nā lungfishes, hoʻokaʻawale ʻia ma nā kahawai o Amazon a me nā ʻāpana ʻē aʻe o ʻAmelika Hema. ma kahi o ka mika ka lōʻihi.

Noho ia i ka wai pāpaʻu a ʻoi aku ka maikaʻi. Ke hiki mai ke kauwela me nā maloʻo, kēia iʻa kūkulu i lua i ka pālolo e mālama i ka makū, waiho i nā lua e ʻae i ka hanu ʻana o ka hū.

Lāʻau mama ʻo ʻApelika

ʻ Hoʻonohonoho Protopterus ʻo ia kekahi o nā iʻa iʻa lung i noho i ʻApelika. Hoʻokomo ʻia e like me ka puhi, ʻoia naʻe nā peʻa loloa a me ka stringy. Noho ia i nā ʻāina o ke komohana a me ka waena o ʻApelika, akā kekahi wahi hikina.

Loaʻa kēia iʻa ʻano maʻamau o ka pō a i ke ao ua hūnā ʻia ia ma waena o nā mea kanu wai. I ka wā maloʻo, ʻeli lākou i kahi lua kahi e komo pākū ai i pili ka waha me ka lewa. Inā hāʻule ka pae o ka wai ma lalo o kā lākou lua, hoʻomaka lākou e hūnā i kahi hua e mālama i ka wai i kou kino.

Pahu lung Australia

ʻO ka Australia lungfish (Neoceratodus forsteri) noho i komohana hema o Queensland, ma Australia, ma ka muliwai Burnett a me Mary. ʻAʻole ia i loiloi ʻia e ka IUCN, no laila ʻaʻole ʻike ʻia ke kūlana mālama, akā ʻo ia pale ʻia e ka ʻaelike CITES.

ʻAʻole like me nā iʻa māmā ʻē aʻe, ka Neoceratodus forsterihoʻokahi wale nō māmā, no laila ʻaʻole hiki ke hilinaʻi wale i ka hanu ʻana o ka ea. Noho hohonu kēia iʻa i loko o ka muliwai, e peʻe ana i ke ao a neʻe mālie i ka papa lepo i ka pō. He holoholona nui lākou, ʻoi aku ma mua o hoʻokahi mika ka lōʻihi i ka wā makua a ma luna o 40 paona o ke kaupaona.

Ke hāʻule ka pae o ka wai ma muli o ka maloʻo, mau kēia mau lungfishes ma lalo, no ka mea hoʻokahi wale nō māmā a pono e hana i ka hanu wai ma o nā ʻīhaʻi.

Inā makemake ʻoe e heluhelu hou aku i nā ʻatikala e like me Iʻa lung: nā ʻano a me nā laʻana, Paipai mākou iā ʻoe e komo i kā mākou Curiosities ʻāpana o ka honua holoholona.
