ʻOiaʻiʻo hoihoi: Ma mua, ua hoʻohana ʻia ke kiʻi o ka sawfish e nā moʻomeheu he nui e like me kahi hōʻailona o ka ʻohana, e laʻa me ka Aztecs.
Ua loaʻa ka inoa ʻo Sawfish mai ke alo ma ke poʻo o kahi iwi ākea e ulu ana me nā ʻūlū, e like me ka pahi olo pālua. ʻO kona inoa ʻepekema ʻo rostrum. ʻO kekahi ʻano o ka manō a me nā kukuna i kēia hiʻohiʻona. Eia nō naʻe, pili ka huaʻōlelo "sawfish" i nā stingray, ka inoa o ke olaola mai ka inoa Lākina "Pristidae" e like me "hole saw" a i ʻole "stingray ihu".
ʻO nā ʻokoʻa ma waena o ka manō saw a me ka sawfish, a huikau pinepine ʻia e nā mea noiʻi ʻike nui loa.

Noʻonoʻo maikaʻi ʻole ʻia ʻo Sawfish, no laila ʻaʻole ʻike ʻia ka helu kikoʻī o kāna ʻano. Eia nō naʻe, ua ʻike ʻia ka ʻepekema he 7 mau ʻano kukuna sawnose: ʻōmaʻomaʻo, ʻAkelanika, ʻEulopa (o nā mea nui loa - a hiki i ka 7 mau mika ka lōʻihi), maikaʻi ka niho, ʻo Australia (a ʻo Kuʻelani paha), ʻAsia a me ka waihona.
ʻOiaʻiʻo hoihoi: ʻai ʻo Sawfish, ʻaʻole naʻe i manaʻo ʻia he kālepa. Ke lawaiʻa, ua like ia me ke trope, no ka mea paʻakikī loa kāna ʻiʻo.
Hoʻokaʻawale ʻia nā kukuna ihu i ʻike ʻia i ʻelua mau pūʻulu, kaukaʻi ʻia i ka nui o nā notches: i hoʻokahi nui lākou, a i kekahi ʻē aʻe - liʻiliʻi. I ka waha, he niho ko ka wahī ʻoi aku ka liʻiliʻi akā like ka nui. Aia i ka ʻano o ka sawfish, mai 14 a 34 mau niho o nā niho o lākou.

Makemake nā kukuna i nā wai kahakai e like me ko lākou wahi noho, no laila paʻakikī loa e loaʻa iā lākou i ke kai ākea i ka hana. ʻO ka pinepine, ʻauʻau lākou i ka wai pāpaʻu kahi haʻahaʻa ka wai. No laila, hiki ke ʻike ʻia ka fin dorsal nui ma luna o ka wai.

Ma Australia, makemake ʻo ia e noho i nā kahawai i nā manawa āpau, me ka ʻoluʻolu loa. ʻAʻole ʻae ka Sawfish i ka wai haumia i ke kanaka. Koho pinepine ka Sawfish i nā pali hana, lalo o ka lepo, limu, nā lepo one e like me ko lākou wahi noho. Hiki ke loaʻa ma kahi kokoke i nā moku kūloko, nā alahaka, nā estuaries a me nā uapo.
He aha ka ʻai a ka iʻa saw?

He mea ʻai ka iʻa iʻa, no laila ʻai ʻo ia i ka poʻe e noho ana i ka wai kai. ʻO ka pinepine, ʻai ia i nā invertebrates e noho ana i ke one a me ka silt ma ka moana kai: nā pāpaʻi, nā ʻōpae a me nā mea ʻē aʻe. ʻIke ka wili i kāna meaʻai ponoʻī ma ka wehe ʻana i ka lepo o lalo me kona ihu ʻano ʻole, ʻeli ʻana iā lākou, a laila ʻai iā lākou.
Eia hou, makemake ka sawnose stingray e hānai i nā iʻa liʻiliʻi e like me ka mullet a me nā lunamakaʻāinana o ka ʻohana herring. I kēia hihia, hū ʻo ia i loko o kahi kula iʻa a no kekahi manawa hoʻomaka e hoʻoluliluli i kāna rostrum i nā ʻaoʻao ʻokoʻa. No laila, hina ka iʻa i kāna notches, e like me ka saber, a hāʻule i lalo. A laila hōʻiliʻili mālie ke kani-ʻeli a ʻai i kāna mea pio. I kekahi manawa ʻūlū ʻia nā kukuna i nā iʻa nui, me ka hoʻohana ʻana i kā lākou notches ma ka rostrum e huki ai i nā ʻāpana o ka ʻiʻo mai iā lākou. ʻO ke kula nui o ka iʻa, ʻoi aku ka nui o ka piʻo a i ʻole ka nui o nā iʻa.
ʻO ka "saw" i kapa ʻia he mea kōkua pū kekahi i ke kani i ka ʻimi ʻana i nā pio, no ka mea, ua hāʻawi ʻia me nā electroreceptors. Ma muli o kēia, maʻalahi ka sawtooth i ka neʻe ʻana o ke ola kai, ke kiʻi ʻana i kahi neʻe iki o ka mea hiki ke lele i loko o ka wai a kanu paha i lalo. ʻO kēia ka mea hiki ke ʻike i kahi kiʻi ʻekolu dimensional o kahi ākea a hiki i ka wai lepo a hoʻohana i kou ulu i nā pae āpau o ka ʻimi. E loaʻa maʻalahi i nā Sawmills i kā lākou mea pio, ʻoiai ma kahi papa wai ʻē aʻe.
Hōʻoia kēia e nā hoʻokolohua i hana ʻia ma nā wahī. Ua hoʻokumu ʻia nā kumuwaiwai o ka hoʻokuʻu uila nawaliwali i nā wahi like ʻole. ʻO kēia mau wahi kahi i hoʻouka ai ke kukuna ihu i mea e hopu ai i nā mea pio.

Ma muli o ke ʻano o ka wahī i kahi hahai holoholona, huhū loa ia. ʻO ka makaʻu keu ke nānā aku ke hoʻohui ʻia me ka like o ka manō. Eia nō naʻe, no ke kanaka, ʻaʻole ia e kau i kahi makaʻu; akā, i ka ʻaoʻao ʻē, ʻaʻole ia he mea maikaʻi ʻole. Ma ke ʻano he kaulike, ke hui ʻana me ke kanaka, hoʻāʻo ka kukuna ihu e hūnā me ka wikiwiki. Eia naʻe, ke hoʻokokoke ʻo ia, e akahele ke kanaka mai huhū iā ia.

Hoʻokahi wale nō hoʻouka kaua ʻole ʻia e kahi lāʻau i kahi kanaka i hoʻopaʻa ʻia. Ua hana ʻia ma ke kai hema o ka Moana ʻAkelanika: ua hōʻeha ʻo ia i ka wāwae o ke kāne. Ua liʻiliʻi ka hiʻohiʻona, ma lalo o hoʻokahi mika ka lōʻihi. Ua hoʻonāukiuki ʻia kekahi mau hihia ʻē aʻe i kū mai ma ke kahawai ʻo Panama. Eia hou, aia kekahi mea i hōʻoia ʻole o ka hoʻouka ʻana o ka wili ma waho o ke kapakai o India.
Aia kekahi manaʻo e pili ana i ka pīhoihoi o ka iʻa ma muli o kona lōʻihi lōʻihi. Eia nō naʻe, ʻo ka ʻoiaʻiʻo, maʻalahi ka wikiwiki o kāna neʻe. ʻIke ʻia kēia i ka dexterity o nā hana, ke ala o ka ʻimi holoholona ʻana i ka mea i hōʻino ʻia a me kāna mea pio.
ʻO ka hapa nui o ka manawa, makemake nā kukuna ʻokiʻoki i ke kai. Koho lākou i ka wai turbid ma kahi e hoʻomaha a alualu ai. Hāʻawi ka sawnuts makua i ka makemake i kahi hohonu hohonu - 40 m, kahi e ʻau ʻole ai kā lākou mau keiki. ʻO ka hapanui pinepine, ʻo ka lā no nā wili ʻana he manawa hoʻomaha ia, akā ala lākou i ka pō.
