Ola ke kohola ʻo Bowhead i ka wai polar. ʻO ke kino o kahi koholā kakaka wahine i hiki i ka lōʻihi o 22 m, ʻoiai nā kāne, ʻano lawa ʻole, ʻo ka nui o kā lākou nui he 18 m.
ʻO ke kaumaha koholā ʻo Bowhead, hiki iā ia mai 75 a 150 mau tona. ʻAʻole kēia he hanana pinepine, i ka hapanui o nā hihia ʻaʻole luʻu ke kohola e like me kēlā, ma ka awelika he 10-15 mau minuke ma lalo o ka wai.
Hele lākou i kahi ʻohana, kahi e māhele ʻia ai i ʻekolu mau hui: nā mākua, oʻo makua a ma lalo o 30 mau makahiki. Ke aʻo ʻana i ka hana, ua ʻike ʻia ka hāʻawi ʻia ʻana o nā wahine a me nā keiki i ke kuleana e hānai mua, ʻo ke koena o ka ʻohana ma hope o lākou.
ʻO ka wehewehe ʻana i ke kohola kohola... ʻO kekahi o nā hiʻohiʻona hiʻohiʻona o ke kohola bowhead ka ʻoi aku ka māmā o ka ʻaoʻao haʻahaʻa o ke kino nui o ke koholā ma mua o ke kala nui.
ʻO kekahi hiʻohiʻona hiʻohiʻona ka nui o nā ā ā. Kiʻekiʻena ka waha o ka koholā a he kinetona ke ʻano o kona ʻano.
ʻO ke poʻo o ke koholā kīʻaha nui loa, e pili ana i ke kino holoʻokoʻa, noho i ka hapakolu o ka lōʻihi holoʻokoʻa o ke koholā. Ma ka hoʻokolokolo pono ʻana i ka hanana, ua kaulana ia ma kahi kokoke i ke poʻo o kēia mammal kahi kahi e like me ka ʻāʻī.
ʻAʻohe o ka niho o ka lunamakaʻāinana o kēia ʻano, eia naʻe, hoʻolako ʻia ka lua o ka waha me ka nui o nā pā whalebone. Mai 3.5 a 4.5 m ko lākou lōʻihi, a ʻokoʻa ka helu o lākou i 400.
Mānoanoa ka papa momona momona subcutane i loko o ka māmele - a hiki i 70 knm, kōkua kēlā ʻano papa e pale pono me ke kaomi i ka luʻu hohonu, mālama i kahi mahana maʻamau, a i ka whale bowhead e like me ka mahana o ke kino o ke kanaka.
Liʻiliʻi nā maka o ke koholā me ke kornea mānoanoa, aia lākou ma nā ʻaoʻao, kokoke i nā kihi o ka waha. I ka wā o ka piʻi ʻana ma hope o ka luʻu hohonu, hiki i ka kohola ke puhi i kahi punawai ʻelua mokulele a 10 mika ke kiʻekiʻe.
ʻAʻohe o nā koholā kūwaho, akā hoʻomohala nui ʻia ka hoʻolohe ʻana. ʻO ka ʻike leo i ka māmela he laulā ākea loa.
ʻO kekahi o nā hana o ka hoʻolohe ʻana i ke koholā polar ua like ia me sonar, mahalo i hiki ai i ka holoholona ke hoʻonohonoho maʻalahi iā ia iho ma lalo o ka wai, ʻoiai ka hohonu hohonu. Kōkua kēia hiki i ka hoʻolohe ʻana i ke koholā e hoʻoholo i nā mamao a me nā wahi.
Wahi koholā ʻo Bowhead - kekahi mau ʻāpana o ke Kai Arctic. ʻO ka hapa nui o nā kula o kēia mau māmela i loaʻa i loko o nā wai anuanu o Chukchi, East Siberian a me Bering Seas.
ʻOi aku ka liʻiliʻi ma ke kai Beaufort a me Barents. I ke kauwela a me ke kauwela, hele nui nā koholā i ke kai anuanu, a i ka hoʻoilo hoʻi lākou i ka ʻaoʻao kahakai.
ʻOiai ʻo ka ʻoiaʻiʻo kohola kik Bowhead ola i nā latitude ʻo Arctic, makemake ʻo ia e neʻe i nā wai maʻemaʻe me ka ʻole o nā wai hau. Inā pono e puka mai kahi kohola ma lalo o ka wai, hiki iā ia ke haki maʻalahi i loko o ka hau 25 cm ka mānoanoa.
Ke ʻano a me ka nohona o ke koholā poʻo poʻo
ʻO nā koholā Bowhead makemake lākou e lilo i nā hipa, akā i kekahi manawa hiki ke loaʻa nā mea hoʻokahi. I kahi mokuʻāina a hiamoe paha, aia ka kohola ma luna o ka wai.
Ma muli o kona nui kupaianaha a makaʻu hoʻi, he mau ʻenemi ko ke koholā kakaka. ʻO kahi kohola hoʻomake wale nō, a i ʻole kahi ʻohana, hiki ke hōʻeha nui i ka māmela, pinepine ka poʻe ʻōpio i hakakā aku i ka ʻohana i mea pio o nā kohola kohola
ʻAʻole pili ka koho kūlohelohe, kūlohelohe i ka heluna kanaka, akā ʻo ka luku nui ʻia ʻana o kēia laha e nā kānaka ua alakaʻi ʻia i kahi hōʻemi koʻikoʻi o ka nui o nā kohola bowhead i ke kūlohelohe. I kēia lā koholā kik Bowhead i ka puke ʻulaʻula, i ka honua a hiki wale i ka 10 tausani mau kānaka. Mai ka 1935, ua kapu loa ka ʻimi ʻana iā lākou.
He aha ka ʻai a ke kohola kohola?
ʻO ka papaʻai nui o ke koholā polar ka plankton, nā crustacea liʻiliʻi a me ka krill. I kēia manawa, komo ka meaʻai i ka lua a me ke kōkua o ke alelo e neʻe i loko o ka esophagus.
Ma muli o ke ʻano maikaʻi o ka whalebone, ma hope o ka kānana ʻana, ʻaneʻane nā plankton a pau, a me nā mea liʻiliʻi loa, e waiho i ka waha o ke koholā. Hoʻokomo ʻia kahi holoholona makua i 2 tone o ka meaʻai i kēlā me kēia lā.
ʻO ka hana hou a me ke ola o ke kohola bowhead
ʻO kekahi hiʻohiʻona o kēia ʻano mamala ka hana ʻana o ke mele moena na ke kāne. ʻO ka pilikino o nā leo a me kā lākou hui pū ʻana i lilo i mele mele kūikawā e paipai i ka wahine e male.
E hoʻolohe i ka leo o ke kohola kakaka
Ma waho aʻe o ke kani ʻana o ke kani, hiki i ka kohola ke lele i waho o ka wai a, i ka manawa o ka luʻu ʻana, hana i ka paʻipaʻi ikaika ma luna o ka ʻili me kona huelo, he mea hoʻohihi hoʻi kēia i ka manaʻo o ka wahine. No nā mahina 6 mua, hānai ʻia ka pēpē, a pili mau ia i ka makuahine.
I ka hala ʻana o ka manawa, hānai ia i nā mākau o ka wahine a hānai iā ia iho, akā hoʻomau me ka wahine no 2 mau makahiki ʻē aʻe. ʻO ka manawa pinepine he mau kānaka pākahi, e like me ka noiʻi, ola no 100 mau makahiki.
Aia kekahi manaʻo ma ke kūlohelohe he mau ʻelele o nā laha, nona nā makahiki i ʻoi aku ma mua o 200 mau makahiki, ʻano laha loa kēia hanana, akā naʻe me kēia, ke koi nei ka laha i ke ʻano hanohano lōʻihi loa i waena o nā mea hānai manu.
ʻO kēia ola wā lōʻihi i hoʻonāukiuki i ka hoihoi i waena o nā ʻepekema a me ka honua holoʻokoʻa. He hiki i nā koholā Polar ke hoʻohui i ka genome piha a me ke kūpaʻa ʻana o ka maʻi ʻaʻa.
