ʻAʻohe o nā ʻano mano e kū like me nā kūpuna o ka wā ʻeono mano... He poʻe koa scuba wiwo ʻole, ke hui hui ʻole ʻia lākou, e hoʻāʻo e holo i kahi manō kakaka a pōʻino ʻole ʻeono mākala. Kupaianaha ka mea kai i kona nui. ʻO kahi hui pū me ia i ke kolamu wai e pīhoihoi i ka manaʻo, e like me ka hālāwai me kahi dinosaur.
Ke kumu o ka laha a me ka wehewehe
Kiʻi: ʻEono manō
ʻO ka manō heʻeono ka nui o nā ʻano i ka ʻohana polygill, kahi ʻano o nā iʻa cartilaginous. Ua ʻike ʻia nā ʻepekema he 8 mau ʻano manō ʻeono kūkae, akā ʻelua wale nō o lākou i kēia lā e piʻo ana i ka moana, a ʻo ke koena ua pau i ka make i ka wā ma mua.
Nā ʻano e kū nei:
- poʻo hina a poʻo hina ʻeono kukū poʻo hina;
- mano manō ʻelima maka nunui.
ʻO ka pūʻulu polygill i manaʻo ʻia ʻo ia ka mea mua loa a ʻo kekahi o nā mea kahiko loa.

E like me nā ʻelele āpau o ka genus o ka iʻa cartilaginous, he helu kā hexagill i kā lākou ʻano ponoʻī.
- ʻaʻohe o lākou ʻauʻau ʻauʻau;
- paepae nā lau;
- uhi ʻia ko lākou kino me nā unahi placoid;
- ka iwi poʻo loa he cartilaginous.
ʻO ka buoyancy o Hexgills kōkua i ka mālama nui ʻana i ke ake nui momona. Eia hou, i ʻole e pohō, neʻe mau ka manō i ke kolamu wai, e kākoʻo ana i ko lākou kino nui me ke kōkua o nā punehune. ʻO nā koena kahiko o kēia mau mea i loaʻa i nā sediment i hiki mai i ka Permian, ʻo Jurassic mua. I kēia lā, 33 mau ʻano o ka manō polygill i manaʻo ʻia ua pau.
ʻIke hoihoi: Ma muli o ko lākou lohi a me ka nui, kapa ʻia nā lunamaka o kēia laha he manō bipi. Kūpono lākou i ka lawaiʻa, akā ʻaʻole kiʻekiʻe loa kā lākou waiwai.
ʻO ka helehelena a me nā hiʻohiʻona
Kiʻi: He aha ke ʻano o ka manō eono kakā
Hiki ke ʻoi aku ka nui o nā kikoʻī o ka manō ʻeono mano i 5 mau mika a ʻoi aku ke kaumaha ma mua o 400 kilokilo. ʻOi aku ka liʻiliʻi o nā ʻāpana maka maka nui. Aia i nā ʻano o ka nohona, ʻokoʻa ke kala o ke kino o ka manō: mai ka hina hina a i ka brown brown.
He ʻōpū māmā ko nā kānaka āpau a me ka laina laina i haʻi ʻia ma ke kino holoʻokoʻa. Hoʻoneʻe ikaika ʻia hoʻokahi fin dorsal i ka caudal, pōkole loa ke kumu, a nui ka ʻūlū o luna a he ʻano notch kona. Aia nā ʻāpana ʻeono mau lālā ma nā ʻaoʻao ʻelua o ke kino i mua o nā wili pectoral.
ʻO ke kino ponoʻī elongated, kahi ololi, fusiform. Pōkole a ʻōlapa ka ihu. I ka ʻaoʻao kiʻekiʻe o ke poʻo ākea aia kahi puka puni - kahi kīʻaha pīpī. Aia nā maka oval ma hope o ka puka ihu a nele i ka membrane nictitating.
ʻO ka waha o ka manō he kaulike me ka nui me nā lālani ʻeono e like me nā ʻano like:
- uhi ʻia ka iwi ā luna me nā niho triangular;
- ma ka iwi ā lalo, he kualapa ko lākou.
Mahalo i kēia hiʻohiʻona, hiki i ka manō ke hopu i nā ʻano heihei like ʻole, me nā mea paheʻe loa.
ʻOiaʻiʻo hoihoi: Noho kēia ʻano manō i ka hapa nui o ka lā ma kahi hohonu loa, e piʻi ana i ka ʻili wale nō i ka pō. Ma muli o kēia ʻano nohona, hiki i ko lākou mau maka ke hoʻomālamalama i nā fluorescently. Manaʻo ʻia kēia mākaukau loa ma waena o nā manō.
Ma hea e noho ai ka manō ʻeono?
Kiʻi: ʻEono mano ʻai i ke kai
Hiki ke loaʻa ʻo Sixgill i ka hohonu o ka Moana ʻAkelanika. Noho ʻo ia i loko o ka wai ma kahakai o ka Pākīpika o ʻAmelika: mai ka lā Kaleponi a hiki i Vancouver ʻākau. Noho ka nui o nā kānaka ma kahakai o Australia, hema o ʻApelika, Chile, kokoke i nā mokupuni ʻo Iapana.
ʻO ka maʻamau maʻamau e loaʻa nā manō ʻeono ma kahi hohonu ma kahi o 100 mau mika, akā ʻike ʻia lākou hiki ke luu i 2000 mau mika a ʻoi paha me ka maʻalahi. Hiki ke kaomi i kēlā mau hohonu ma mua o 400,000 kg i kēlā me kēia mika mika. I ke ao, neʻe mālie kēia mau mea i ke kolamu wai, e holoholo ma lalo e ʻimi i ke kupapaʻu, a kokoke i ka pō e piʻi kokoke i ka papa e ʻimi iʻa. Ma mua o ka wanaʻao, hoʻi hou nā pilikua prehistoric i ka hohonu. Ma waho o ke kapakai o Kanada, loaʻa ʻo Hexgill i ka papa o ka wai a i ke ao, akā hiki ke kapa ʻia kēia he ʻokoʻa ʻokoʻa.
ʻOiaʻiʻo: ʻO ka manō kūleʻa poʻoʻeono mākia ke koʻikoʻi o ka ʻoihana. Ua koi nui ʻia ʻo ia ma Kaleponi, kekahi mau ʻāina ʻEulopa. Māloʻo pinepine ʻo ia.
ʻIke ʻia ma Kelemānia kaʻiʻo o kēia manō e hoʻohana ʻia ma ke ʻano he laxative maikaʻi. ʻAʻole ʻai ʻia ke akepaʻa o ke kanaka nunui, no ka mea, ua manaʻo ʻia he lāʻau make ia ma muli o ke kiʻekiʻe o nā toxins.
He aha ka ʻai a ka manō ʻeono?
Kiʻi: ʻeono mano kai hohonu
ʻO ka papaʻai maʻamau o nā pilikua prehistoric:
- nā iʻa like me waena e like me flounder, hake, herring;
- crustaceans, kukuna
Aia kekahi mau hihia ke hoʻouka kēia ʻano manō i nā sila a me nā holoholona kai ʻē aʻe. ʻAʻole hoʻowahāwahā nā gills ʻeono i ke kino make, hiki iā lākou ke lawe i ka waiwai pio mai kā lākou mea hoʻouluulu a i ʻole hoʻouka aku iā ia, keu hoʻi inā nāwaliwali ke kanaka ma muli o nā ʻeha a ʻoi iki paha ka nui.
Ma muli o ke ʻano kūikawā o nā ā ā a me ke ʻano o nā niho, hiki i kēia mau meaola ke ʻai i nā meaʻai like ʻole. Hana maʻalahi lākou me nā crustacea nui. Inā hopu ka mea ʻaihue i ka mea pio me kāna mau ā ikaika, a laila ʻaʻohe ona manawa e ola hou ai. Hoʻomaka ka lōlō e hoʻoluliluli i kona poʻo mai kēlā ʻaoʻao a i kēia ʻaoʻao a kaʻapuni i kona kino, a laila e hōʻino ana i ka mea i loaʻa iā ia. Ma waho wale lākou e nānā keu, akā i ka wā o ka hahai holoholona hiki iā lākou ke hoʻouka i nā uila.
ʻOiai ko lākou nui a maka weliweli hoʻi, manaʻo ʻia nā bipi manō ʻaʻole weliweli i nā kānaka. I loko o ka mōʻaukala holoʻokoʻa o ka nānā ʻana iā lākou, ua hoʻopaʻa ʻia nā hihia he nui i ka poʻe, akā i loko o kēlā me kēia mea i hoʻonāukiuki ʻia ka manō e nā hana kūpono ʻole o nā mea like ʻole. Ke hui ʻana i kahi kanaka ma kahi hohonu, hōʻike kēia mau mea i kona hoihoi iā ia a me nā pono hana ma lalo o ka wai. Hiki iā lākou ke hoʻopuni i ka ʻaoʻao a me ka ʻaoʻao no kekahi manawa, akā me ka hoʻāʻo ʻana e hoʻāʻo, ʻau koke lākou.
Nā hiʻohiʻona o ke ʻano a me ka nohona
Kiʻi: Mano ʻeono mano
He paʻakikī loa e nānā i ka hexgill i ko lākou wahi maoli, no ka mea makemake lākou e ʻau i ka hohonu hohonu. E like me nā poʻe noho kai hohonu o ke kai a me nā moana, ua noho lōʻihi lākou i ke ʻano pohihihi i nā kānaka. ʻAʻole kūpono e hoʻokiʻekiʻe kūikawā i nā manō ʻeono mākāhā i ka ʻili, no ka mea ua lilo koke lākou i mea leʻaleʻa a hana atypically. ʻO kēia ke kumu o ka haʻalele ʻana o nā biologists i kēia ʻano aʻo.
Ua loaʻa i nā ʻepekema kahi ʻano ʻokoʻa i kēia mau pilikua - ua hoʻomaka lākou e hoʻopili i nā mea ʻikepili kūikawā i ke kino o ka onoono.

Kaulana kēia mau mea ola mehameha. Hoʻohālikelike ʻia lākou e ka neʻe ʻana i kēlā me kēia lā i ka kolamu wai. Aia kekahi mau hihia o ka cannibalism, i ka wā i hoʻouka kaua nā mākua olakino olakino i nā ʻohana maʻi a i ʻole nā mea i hihia ʻino i nā ʻupena lawaiʻa. ʻO ka manō liʻiliʻi, ka nui o ka manō ʻeono maka nunui, ʻoi aku ka liʻiliʻi ma mua o ka manō pōkā poʻohina ʻeono mano. No kēia kumu, ʻaʻole aʻo ʻia kona ʻano a me nā ʻano hānau.
ʻO ke kūkulu kaiāulu a me ka hana hou
Kiʻi: Mano ʻeono mano
ʻO nā kānaka nunui ʻeono kānana he ovoviviparous. I loko o ke kau, hiki i ka wahine ke hānau i ke awelika o 50-60 manō, akā aia kekahi mau hihia ke hōʻea kā lākou helu i hoʻokahi haneli a ʻoi paha. Hoʻomaopopo ʻia ʻo ka nui o ke ola o nā holoholona ʻōpio he 90 pākēneka, kahi hōʻailona kiʻekiʻe loa. ʻIke ʻia ua hiki i nā manō huluhulu ke hānau i 4 a 10 mau cubs a ʻo ko lākou ola he 60 pākēneka wale nō.
Hiki i kēlā me kēia kanaka ke oʻo moekolohe ke ʻoi aku ko lākou lōʻihi ma mua o ʻelua mau mika. Ma hope o ka momona, hoʻomau nā hua i ko lākou ulu ʻana i loko o ke kino o ka wahine i loko o kahi keʻena brood kūikawā, e loaʻa ana ka meaʻai kūpono mai ka ʻeke yolk.

ʻOiaʻiʻo: Ma ka lalo o ke Kai Kaiwaena, ma kahi hohonu, ʻike pinepine ʻia nā lua he nui, a hiki i 2-3 mau mika ka hohonu. Manaʻo nā kānaka biologists, he mau kuhi kēia o ka ʻimi holoholona ʻana i nā manō ʻeono no nā crustacea nunui.
