Whale whale amakhala moyo m'madzi ozizira. Thupi la chinsomba chachikazi limafikira kutalika kwa 22 m, pomwe amuna, oddly mokwanira, kukula kwawo ndi 18 m.
Kulemera kwa nsomba yamphongo, itha kukhala kuyambira matani 75 mpaka 150. Izi sizimachitika kawirikawiri, nthawi zambiri nsomba sizimayenda motere, pafupifupi mphindi 10-15 zili pansi pamadzi.
Amasamukira m'mapaketi, momwe amagawika m'magulu atatu: achikulire, okhwima ogonana komanso ochepera zaka 30. Mukamaphunzira zamakhalidwe, zinawonetsedwa kuti zazikazi ndi ana amapatsidwa mwayi wodyetsa koyamba, gulu latsalira la mzere kumbuyo kwawo.
Kufotokozera kwa whale mutu... Chimodzi mwazinthu zofunika kwambiri za nangumi wam'mutu ndikuti gawo lakumunsi la namgumiyo ndi wopepuka kuposa utoto waukulu.
Mbali ina yomanga ndi kukula kwa nsagwada. Pakamwa pa namgumiyo ndiwokwera ndipo mawonekedwe ake ndi ofanana.
Mutu wa nangumi wamkulu ndi waukulu kwambiri, poyerekeza ndi thupi lonse, umakhala gawo limodzi mwa magawo atatu a kutalika kwa namgumiyo. Poyang'anitsitsa kapangidwe kake, zidadziwika kuti pafupi ndi mutu wa nyamayi pali malo omwe amafanana ndi khosi.
Yemwe akuyimira mtunduwu alibe mano, koma pakamwa pamakhala ndi mbale zingapo za whalebone. Kutalika kwawo ndi kuchokera 3.5 mpaka 4.5 m, ndipo kuchuluka kwawo kumasiyana mpaka 400.
Mafuta osanjikiza a nyama yaying'ono kwambiri - mpaka 70 cm, wosanjikiza wotere amathandizira kuthana bwino ndi kupsinjika kwakatikati mwamadzi, amakhala ndi kutentha kwabwino, komwe m'nkhono zam'mutu muli chimodzimodzi ndi kutentha kwa thupi la munthu.
Maso a nangumiwo ndi ang'ono ndi khungu lakuda, lomwe lili pambali, pafupi ndi ngodya za kamwa. Pakukwera pambuyo pomira m'madzi, namgumiyo amatha kuphulitsa kasupe wa ndege ziwiri mpaka 10 m kutalika.
Anangumi alibe mphuno zakunja, koma kumva kumapangidwa bwino. Kuzindikira kwamphamvu kwa nyama yoyamwitsa kumakhala kosiyanasiyana.
Zina mwa ntchito zakumva mu namgumi wa polar ndizofanana ndi sonar, chifukwa chomwe nyamayo imatha kudziyendetsa pansi pamadzi, ngakhale pansi kwambiri. Malo akumvawa amathandiza namgumi kudziwa malo ndi malo.
Malo okhala ndi nsomba zam'madzi - madera ena a m'nyanja ya Arctic. Makamaka masukulu a zinyama izi amapezeka m'madzi ozizira a Chukchi, East Siberia ndi Bering Seas.
Zachilendo ku Beaufort ndi Barents. M'nyengo yachilimwe ndi chilimwe, anamgumi amapita kutali m'madzi ozizira, ndipo nthawi yozizira amabwerera m'mphepete mwa nyanja.
Ngakhale zili choncho Whale mutu amakhala kumalo ozungulira Arctic, amakonda kusuntha m'madzi oyera opanda ayezi. Nangumi akafunika kuti atuluke m'madzi, amatha kupyola ayezi wokwanira masentimita 25.
Chikhalidwe ndi moyo wa nsomba zam'mutu
Namgumi wamutu Amakonda kukhala pagulu, koma nthawi zina mutha kupezanso anthu osakwatira. Mukapuma kapena kugona, namgumiyo ali pamwamba pamadzi.
Chifukwa cha kukula kwake kochititsa chidwi komanso kochititsa mantha, namgumiyo ali ndi adani ochepa. Namgumi wakupha yekha, kapena gulu lankhosa, ndi amene angawononge chiweto chachikulu, makamaka achinyamata omwe adalimbana ndi gulu la nkhandwe.
Kusankhidwa kwachilengedwe, kwachilengedwe sikukhudza anthu, koma kuwonongedwa kwa mitundu iyi ndi anthu kwadzetsa kuchepa kwakukulu kwa anamgumi amutu m'chilengedwe. Lero Whale wansomba m'buku lofiira, padziko lapansi pali anthu opitilira 10 zikwi zokha. Kuyambira 1935, kuwasaka kwakhala koletsedwa.
Kodi nsomba zam'mutu zimadya chiyani?
Chakudya chachikulu cha nsomba za polar ndi plankton, crustaceans ang'ono ndi krill. Pakadali pano, chakudya chimalowa m'mimbamo ndipo mothandizidwa ndi lilime limasunthira kummero.
Chifukwa cha mawonekedwe abwino a ankhandwe, atasefa, pafupifupi mitengo yonse, ngakhale tinthu tating'onoting'ono kwambiri, timatsalira mkamwa mwa nyangayo. Nyama yayikulu imatenga matani 2 azakudya patsiku.
Kubereka ndi chiyembekezo cha moyo wa nangumi wam'mutu
Chimodzi mwazinthu zamtundu wamtunduwu ndizomwe zimayimba nyimbo yamwamuna. Kumveka kwa mamvekedwe ndi kaphatikizidwe kake kamasanduka nyimbo yapadera yomwe imalimbikitsa wamkazi kuti agone.
Mverani mawu a nangumi
Kuphatikiza pakuphatikizika kwamawu, namgumi amatha kulumpha m'madzi ndipo, panthawi yomiza, amatha kuomba mmanja pamtunda ndi mchira wake, izi zimakopanso chidwi chachikazi. Kwa miyezi 6 yoyambirira, mwana amayamwitsidwa mkaka, ndipo amakhala pafupi ndi mayi nthawi zonse.
Popita nthawi, imakhala ndi maluso azimayi ndikudziyendetsa yokha, koma imapitilizabe kukhala ndi wamkazi zaka ziwiri. Nthawi zambiri pamakhala anthu omwe, malinga ndi kafukufuku, amakhala zaka zopitilira 100.
Pali malingaliro kuti m'chilengedwe pali oimira mitunduyo, omwe zaka zawo zoposa 200, zodabwitsazi ndizosowa kwambiri, koma ngakhale zili choncho, mtunduwo umati ndiwopatsa ulemu pakati pazinyama.
Kukhala kwanthawi yayitali kunadzutsa chidwi chachikulu pakati pa asayansi, padziko lonse lapansi. Anangumi a m'nyanja zam'madzi ali ndi kuthekera kwa majini komwe kumalumikizidwa ndikukonzanso kwathunthu kwa ma genome komanso kukana khansa.
