I ke kai ʻākau, hiki iā ʻoe ke ʻike i kahi māmalū maʻamau i kapa ʻia ʻo "beluga". ʻO kēia holoholona ka loulou waena ma waena o ka iʻa me kahi kohola. He ʻano like ko nā kūwaho me ka dolphin, akā i ka nui e like me ke koholā. I ke ola o kēlā me kēia lā ua kapa ʻia ʻo ia "dolphin polar».
Nā hiʻohiʻona a me nā wahi noho o nā koholā beluga
ʻO ka koholā Beluga (mai ka Lat. Delphinapterus leucas) kahi māmela nui, ka ʻohana narwhal, nā ʻohana poʻomanaʻo - nā koholā niho. Manaʻo ʻia kahi dolphin ma muli o kona ʻano - nā kai o ka Moana ʻĀkau a me nā waihona kai.
ʻO ka hoʻoili ʻana he palahalaha (50-80 kekelē ʻākau latitu). Belukha ola i ke kai aʻe: Bering, White, Okhotsk, komo i kekahi manawa i ke kai ʻo Baletika. I ka wā o nā kahawai hiki iā ia ke kiʻi i nā kahawai: Ob, Yenisei, Lena. Wahi a kekahi hōʻike, aia kekahi kaʻawale ka nui o ka koholā beluga ma loko o ka muliwai St. Lawrence.
Nui ia i ka nui: hiki i ke kāne ke lōʻihi o 6 mika, ka wahine - a i 5 mika. ʻO ke kaumaha o ke kino mai 1.5 a 2 ton. ʻO kahi hiʻohiʻona hiʻohiʻona o ka dolphin beluga kona poʻo, ʻaʻole ʻae ia e huikau me kekahi mea ʻē aʻe.
Hiki iā ia ke hoʻohuli i kona poʻo, ʻaʻole ia he ʻano maʻamau no nā koholā. Hoʻomaopopo ʻia kēia e ka vertebrae cervical accrete. ʻO nā kepa ma ka umauma he oval, liʻiliʻi i ka nui. ʻO nā koholā Beluga, ʻokoʻa i nā dolphins, nele i kahi fin ma ko lākou kua, ʻo ia ke kumu i kapa ʻia ai lākou he "dolphins wingless".
Waihoʻoluʻu dolphin beluga ʻokoʻa a hilinaʻi i ka pili kahiko. ʻO nā keiki hānau wale nā polū a me ka uliuli polū. ʻO nā kānaka i hōʻea i hoʻokahi makahiki e pale i ka pale, loaʻa iā lākou ke kala hina a hina hina. I kekahi manawa hoʻololi ke kala i kahi kala bluish maʻalea. ʻO nā lunamakaʻāinana o ka heluna makahiki 3-5 mau makahiki keʻokeʻo keʻokeʻo.
Ke ʻano a me ka nohona o nā koholā beluga
Mālama ʻo Belugas i ka ʻohi hipa. Aia nā pūʻulu e like me kēia: he wahine me nā keiki a i ʻole nā kakini kāne he ʻumikūmālua. ʻO ke ala o ke ola ka neʻe ʻōnaehana kau.
I ka hoʻoilo, hoʻāʻo lākou e hoʻomau i ka lihi o ka wai hau. ʻO ka pinepine i ka wā hoʻoilo, kahi ʻohana beluga nakinaki ʻia e ka hau mānoanoa a no nā mea he nui weliweli ia. Hele pinepine nā pūʻulu i ka hema ke loaʻa i nā uhi i ka lihi hau mānoanoa.
I ka puna, neʻe mālie nā hipa i ka wai papau, i nā estuaries, bay, fjords. Pili kēia hana i ka molt makahiki. Ua wāwahi lākou i ka papa make o luna e ka ʻānai ʻana i nā ʻiliʻili a i nā kapa paʻakikī.
Mālama mau ʻia ka neʻe ma hoʻokahi ala. ʻO ka ʻoiaʻiʻo dolphin beluga Hoʻomanaʻo ʻo ia i kona wahi hānau a hoʻāʻo e hoʻi i laila i kēlā me kēia makahiki. Hiki iā Beluga ke noʻonoʻo ʻia he mea ola pilikino piha i kahi hui. No ka mea ua hoʻomohala lākou i ka kamaʻilio: me ke kōkua o ke kani, ka ʻōlelo o ke kino a me ka helehelena.
Ua helu nā ʻepekema a i nā kani like ʻole he 50 i hiki i kēia holoholona ke hana. Kāhea nā luina kohola beluga "Ka canary o ke kai." ʻO ke ʻano o ka holoholona he ʻano maikaʻi, wehewehe kēia i kona ʻano nui i ka dolphin. ʻAe kūpono i ke aʻo ʻana, hiki iā ʻoe ke ʻike pinepine i nā hana keaka puni me ko lākou komo ʻana. Aia kekahi mau hihia i ʻike ʻia no ke ola kanaka dolphin polar.
Mea ʻai kohola Beluga
Belukha māmele hānai nui i ka iʻa. ʻAʻole pau ka ʻai ʻana i ka hopu ʻana i ke kupapaʻu, akā i ka omo ʻana me ka wai. ʻO kahi mākua, ma ka awelika, ʻai a 15 kg o ka iʻa i kēlā me kēia lā.
ʻAi pinepine ʻo ia i ka crustacea a me ka plankton. Aloha nui ʻo ia i nā ʻalemona salmon, mākaukau e neʻe ma hope o lākou ma o nā kaukani mile. Ma muli o kēia, ʻau pinepine i nā kahawai hohonu a me nā kai kūʻono nui.
ʻO ka hana hou a me ke ola o nā koholā beluga
Hoʻomaka ka wā o nā hauʻoli hauʻoli no ka belugas i ka wā o ka puna-kauwela. E hana i kēia, koho lākou i nā kahakai mālie. Eia lākou e male ai a hānau keiki. Hakakā pinepine nā kāne me ka hanohano no ka nānā o ka wahine. Loaʻa ke oʻo makua i nā kāne i ka makahiki 7-9 mau makahiki, a i nā wahine - ma 4-7 mau makahiki.
Wahine polar dolphin beluga hapai i hoʻokahi keiki no 14 mau mahina. Lawe ʻia ka hoʻohui i hoʻokahi manawa i kēlā me kēia ʻelua a ʻekolu mau makahiki paha. Hānau ka wahine i ka wai mehana, kokoke i kai.
Hānai ʻo ia i ka pēpē me ka waiū no 12-24 mau mahina. I ka wā hānau, hiki i ka cub i ka lōʻihi ma kahi o 1.5 mau mika. Kākaʻikahi nā māhoe. Pau nā hānau kohola Beluga i ko lākou hala iwakālua mau makahiki. ʻO ka makahiki maʻamau i hiki i kahi māmele ma ka pae 30 a 40 mau makahiki. ʻO ka pōmaikaʻi nui o ke koholā beluga kona dexterity kupaianaha a me ka pale ʻana.
ʻO ka wikiwiki maʻamau o ke kanaka makua i 3-9 km / h, ke makaʻu - a 22 km / h. Ka hiki ke noho pio i lalo me ka ʻole o ka ea ma kahi o 15 mau minuke. Puka mai kēlā me kēia me ka hapa mau minuke i ka hanu.
Haahaa ka ʻike ʻana i nā koholā beluga, no laila loaʻa iā lākou ka ʻike e pili ana i nā mea kokoke e hoʻohana ana i kahi echo. Hoʻopuka lākou i nā ultrasounds click-shaped (aia he ʻeke ea kūikawā). ʻO kahi ʻāpana ʻokoʻa o ka lolo e heluhelu i nā ʻikepili āpau e pili ana i nā mea kokoke. Hoʻopili kēia i kahi aniani acoustic ma ka lae.
ʻO ka manawa weliweli loa no dolphin polar - ʻo kēia ka hoʻoilo. Ma waho aʻe o ka hiki i nā ʻohana hipa ke hāʻule i loko o ka hoʻopaʻa pio ʻana o ka hau, he ʻenemi kūlohelohe ko lākou. ʻO ka weliweli loa ka kohola kohola. He paʻakikī e hūnā iā ia a hoʻopau pinepine ka alualu ʻana i ka holo pono ʻole. No laila, hoʻāʻo nā koholā beluga ʻaʻole e ʻau mamao i ke kai.
ʻO kekahi predator weliweli e makemake e ʻahaʻaina i nā koholā beluga ka bear polar. I ka wā hoʻoilo o nā māmela, nānā ʻo ia iā lākou ma kahi kokoke i ka lihi o ka wai a hoʻoliʻiliʻi i ka holoholona me ka pā ikaika o kāna ʻūwi manamana.
I kēia mau lā, ua ʻike ʻia kekahi mea maikaʻi ʻole e hōʻemi ana i ka heluna kanaka o kēia mau holoholona - ke kaiapuni. Hoʻokuʻu ʻia ka nui o nā ʻōpala ʻino i loko o ka wai kai, e koi ana i nā hipa e neʻe i nā wahi anuanu loa. ʻO lākou ka mea i lilo i hei no ka lehulehu o nā kānaka; kū wale ka kohola beluga i ke kai.
Kohola Beluga - kahi punahele o ka poʻe e hoʻolohe ana i nā aquarium nui. ʻO ka holoholona e hana maʻalahi i ka launa ʻana, kū a ʻae iā ia iho e paʻi kiʻi ʻia. Nui ka manaʻo i ke pio ʻana a he hoalauna maikaʻi loa ia no nā poʻe aquarium ʻē aʻe.
Hiki iā ʻoe ke ʻike pinepine i ka belugas e hana ana i ka circus, hana lākou i kahi hana maikaʻi loa me nā hana, maʻalahi lākou e hoʻomaʻamaʻa. Ma kiʻi o beluga huli e aneane keʻokeʻo hau, e like me nā ʻānela e iho ana i ka wai.
