He aha ke ʻano o ka iʻa?

ʻO ka iʻa (Pisces, mai ka Latin piscis = iʻa) he mau ʻōuli wai me ka hanu gill. ʻAʻole wehewehe ka papa iʻa i kahi papa paʻa ponoʻī, e like me ke ʻano o nā mammals, nā manu, nā amphibians, a me nā mea kolo, akā hōʻuluʻulu i kahi hui o nā holoholona like ʻole.

Ma ka Geologically, ua ʻike ʻia ka iʻa mua ma kahi o 480 miliona mau makahiki i hala ma ka Ordovician. I kēia mau lā, ʻike ka poʻe loea i ka ʻokoʻa ma waena o 33,000 mau ʻano iʻa, a ke hoʻoponopono mau ʻia nei kēia helu i luna i ka ʻike ʻia ʻana o nā ʻano iʻa hou.

Ma ke kumu, hiki ke hoʻokaʻawale ʻia nā ʻano iʻa ʻelua:

• Nā iʻa carilaginous: Nā iwi i hana ʻia me ka cartilage, e laʻa me ka manō a me ka ray
• ʻO ka iʻa iʻa: Nā iwi iwi, e like me ka salmon a me ka iʻa

'Ōlelo Aʻo: ʻOiai ke ʻano o waho a i ʻole ka noho ʻana, ʻaʻole iʻa nā koholā, penguins, a me nā iʻa.

Nā ʻano o ka iʻa

Hoʻohui ka papa o nā iʻa i kekahi mau hiʻohiʻona, e like me ka laʻana i ka hanu gill, nā ʻili no ka locomotion a me nā unahi i mea pale pale. Eia nō naʻe, ʻaʻole i loaʻa i kēlā me kēia ʻano iʻa nā hiʻohiʻona a pau i helu ʻia ma aneʻi. ʻO ke kumu o kēia ka hoʻomohala lōʻihi o ka phylogenetic, i ka wā i ulu ai nā hōʻike like ʻole.

Fins: Hoʻohana ka iʻa i ko lākou mau peʻa e neʻe ai.

Hoʻohua hou: ʻAʻole hoʻopili ka hapa nui o nā iʻa. Hoʻomoʻa ʻia nā hua i ka wai.

ʻAʻala: ʻO ka manaʻo nui loa o ka iʻa ʻo ia ka ʻala. ʻIke maikaʻi ʻole ka iʻa i ko lākou puni.
ʻO ka hanu ʻana: Hoʻomoʻa ka iʻa i ka oxygen i hoʻoheheʻe ʻia i loko o ka wai ma o kā lākou gills.

Spawn: Hāpai ka iʻa mai nā hua i kapa ʻia ʻo spawn. He mau iʻa viviparous kekahi, akā me ia mau iʻa e ulu ai ka iʻa mai nā hua, ʻoiai ma ke kino o ka iʻa.

Poikilothermy: He koko anu nā i'a a pau. Hoʻoholo ʻia ka mahana o kou kino e ka wela o waho.

ʻO nā ʻāʻī: Aia nā ʻāʻī ma lalo o ka unahi. ʻO ka mea huna huna e pale aku i ka maʻi bacteria a hoʻemi i ke kūʻē frictional i loko o ka wai, e ʻae ana i ka iʻa e ʻau wikiwiki.

Nā unahi: Hoʻomalu ka mea kaua unahi i ka iʻa mai nā hoʻoikaika mechanical o waho.

ʻAuʻau Puke: He ʻauʻau ko nā iʻa iwi āpau. ʻO kēia ka mea e hiki ai i ka iʻa ke hoʻoponopono i ka holo ʻana o ka wai.

ʻO ke kino laina ʻaoʻao: ʻO ka ʻōkana laina ʻaoʻao kahi mea ʻike kūikawā i hoʻohana ʻia e ʻike i nā neʻe.

Aia nā pūnaewele sensory pili ma ka ʻaoʻao hema a ʻākau o ke kino.
Nā Vertebrates: Ma ke ʻano he vertebrates, he iwi kuamoʻo ko ka iʻa.

Papa inoa o nā iʻa

Eel, frogfish, brown trout, barbel, barracuda, blobfish, clownfish, cod, flounder, perch, trout, iʻa gula, guppy, mano, hammerhead shark, pike, cod, carp, dogfish, koi carp, puffer fish, salmon, mackerel, pulupulu, Sunfish, moray eel, pirana, burbot, coelacanth, rainbow trout, ray, redfish, anchovy, tench, plaice, swordfish, seahorse, turbot, sturgeon, tiger shark, tuna, catfish, walleye, uila uila.

He vertebrates ka iʻa. Hoʻomoʻa ka iʻa i ka oxygen ma o ko lākou gills.
Ua ʻike ʻia ka iʻa mua ma ka moana 480 miliona makahiki aku nei.
Ma kahi o 33,000 mau ʻano iʻa i ʻike ʻia e paʻa nei i ke kai a me ke kai. ʻOi aku ka nui o ka helu maoli o nā ʻano.

He aha ka iʻa naʻauao loa?

"ʻO ia kekahi o nā mea maikaʻi loa aʻu i ʻike ai ma lalo o ka wai." Manaʻo ʻia nā kukuna Manta he akamai loa. Loaʻa iā lākou ka lolo nui loa o nā iʻa, a ua hala nā kukuna manta nunui i ka mea i kapa ʻia ʻo ka hōʻike aniani i kahi noiʻi 2016.

He aha ka iʻa nui loa ma ka honua?

Manō Whale: ʻO ka iʻa nui loa.

Ua make wai ka iʻa?

Kapa ʻia kēia kaʻina hana osmosis. Pono ka i'a e uku no ka lilo o ka wai: makewai. Lawe lākou i ka wai nui me ko lākou waha, inu lākou i ka wai paʻakai.

Hiki i ka i'a ke poho?

ʻAʻole, ʻaʻole ia he hoʻohenehene: hiki i kekahi iʻa ke poho. No ka mea, aia nā ʻano ʻano e pono e piʻi mau a hauʻoli i ka ea. Inā hōʻole ʻia ke komo ʻana i ka ʻili wai, hiki iā lākou ke poho maoli ma lalo o kekahi mau kūlana.

Pehea ke ʻano o ka iʻa e ola ai i ka wai?

Ma kahi o ka māmā, he ʻiʻo ko ka iʻa. ʻO lākou ka hoʻololi koʻikoʻi i ke ola wai. Hiki i nā gills ke neʻe i ka iʻa i loko o ka wai me ka ʻole e piʻi mai i ka ea ma ka ʻili.
