Nyama narwhal Ndi nyama ya m'nyanja ya m'banja la narwhal. Ndizochokera ku dongosolo la cetaceans. Ichi ndi chinyama chodabwitsa kwambiri. Ma Narwhal amatchuka chifukwa chokhala ndi nyanga yayitali (mano). Ndi wamitala 3 ndipo amatuluka pakamwa.
Maonekedwe ndi mawonekedwe a Narwhal
Narwhal wamkulu amafika kutalika kwa pafupifupi 4.5 mita, ndi ng'ombe 1.5 mita. Poterepa, amuna amalemera pafupifupi matani 1.5, ndipo akazi - 900 makilogalamu. Oposa theka la kulemera kwake kwa nyama amapangidwa ndi mafuta. Kunja, ma narwhal amafanana ndi belugas.
Mbali yapadera ya narwhal ndi kupezeka kwa mng'oma, womwe nthawi zambiri umatchedwa nyanga. Minyanga ya njovu imalemera pafupifupi 10 kg. Zilombazo zimakhala zolimba kwambiri ndipo zimatha kupindika mbali mpaka mtunda wa 30 cm.
Mpaka pano, ntchito za minyanga ya njovu sizinaphunzirebe zenizeni. M'mbuyomu zimaganiziridwa kuti narwhal amafunikira kuti amenyane ndi wozunzidwayo, komanso kuti nyamayo idutse kuphulika kwa madzi oundana. Koma sayansi yamakono yatsimikizira kupanda maziko kwa chiphunzitsochi. Pali ziphunzitso zina ziwiri:
Ng'onayo imathandiza amuna kukopa zazikazi pamasewera olimbirana, popeza ma narwhal amakonda kukolowola zitsamba zawo wina ndi mnzake. Ngakhale, malinga ndi lingaliro lina, ma narwhal amapaka ndi nyanga kuti ziyeretsedwe pazambiri ndi magawo ena amchere. Komanso, mano amafunika kwa amuna pamipikisano yokwatirana.
Narwhal Tusk - Ichi ndi chiwalo chovuta kwambiri, pamwamba pake pamakhala mathero ambiri, chifukwa chake lingaliro lachiwiri ndiloti nyama imafunikira mkombero kuti izindikire kutentha kwa madzi, kuthamanga kozungulira, komanso mafupipafupi amagetsi. Amachenjezanso achibale za zoopsa.
Narwhals amadziwika ndi kuzungulira kwa mutu, maso ang'onoang'ono, mphumi yayikulu pamphumi, pakamwa pang'ono, komwe kumakhala kotsika. Mthunzi wamthupi ndi wopepuka pang'ono kuposa mthunzi wamutu. Mimba ndi yopepuka. Kumbuyo ndi mbali zanyama kuli mawanga ambiri ofiira-bulauni.
Narwhal alibe mano. Nsagwada zakumtunda zokha ndizomwe zimakhala ndi mikoko iwiri. Mwa amuna, popita nthawi, dzino lakumanzere limasanduka mano. Pamene akukula, amapyoza mlomo wake wapamwamba.
Mikwingwirima imapinda mozungulira mozungulira ndipo imafanana ndi yolowa. Asayansi sanazindikire chifukwa chomwe mkombowo umakulira kumanzere. Izi zikadali chinsinsi chosamvetsetseka. Nthawi zambiri, mano onse a narwhal amatha kukhala nyanga. Kenako adzakhala nyanga ziwiri, monga tikuonera chithunzi cha nyama narwhal.
Dzino lamanja mu narwhals limabisidwa mu chingamu chapamwamba ndipo silikhudza moyo wa nyama. Komabe, sayansi mwina ikudziwa kuti ngati Unicorn wanyanja narwhal kuthyola nyanga yake, kenako chilondacho m'malo mwake chidzamangirizidwa ndi minofu ya mafupa, ndipo nyanga yatsopano sidzakula pamenepo.
Nyama zoterezi zimapitilizabe kukhala ndi moyo wathunthu wopanda chovuta chilichonse chifukwa chosowa lipenga. Mbali ina Nyama zam'madzi narwhal Kodi kusapezeka kwa dorsal fin. Amasambira mothandizidwa ndi zipsepse zam'mbali ndi mchira wamphamvu.
Malo okhala Narwhal
Narwhals - nyama za ku Arctic. Ndi malo ozizira omwe amafotokozera kupezeka kwa mafuta ambiri atinyama tating'onoting'ono. Malo omwe amakonda kwambiri zinyama zapaderazi ndi madzi a m'nyanja ya Arctic, dera la Canada Arctic Archipelago ndi Greenland, pafupi ndi Novaya Zemlya ndi Franz Josef Land. M'nyengo yozizira, amapezeka ku White and Berengo Seas.
Chikhalidwe ndi moyo wa narwhal
Ma Narwhal amakhala m'malo otseguka pakati pa ayezi. M'nyengo yophukira ziphuphu za unicorn amasamukira kumwera. Amapeza mabowo mu ayezi okutira madzi. Gulu lonse la narwhals limapuma kudzera m'mabowo. Ngati bowo litaphimbidwa ndi ayezi, ndiye kuti amuna amaswa ayezi ndi mutu wawo. M'nyengo yotentha, nyama, m'malo mwake, imasunthira kumpoto.
Narwhal imamva bwino pakuya mamita 500. M'madzi akuya, narwhal imatha kukhala opanda mpweya kwa mphindi 25. Narwhals ndi nyama zoweta. Amapanga magulu ang'onoang'ono: 6-10 aliyense payekha. Amalumikizana ndi mawu, ngati ma belugas. Adani a nyama za ku Arctic ndi anamgumi opha ndi zimbalangondo zakumtunda; nsombazi ndi zoopsa kwa ana.
Chakudya cha Narwhal
Unicorn wam'nyanja amadyetsa zamoyo zam'madzi zakuya monga halibut, polar cod, Arctic cod ndi redfish. Amakondanso ma cephalopods, squid ndi crustaceans. Amasaka mwakuya kwa kilomita imodzi.
Mano ogwira ntchito a narwhal amakhulupirira kuti amagwiritsidwa ntchito kuyamwa ndikutulutsa ndege. Izi zimapangitsa kuti athe kuchotsa nyama, monga nkhono kapena nsomba zapansi. Ma Narwhal ali ndi makosi osinthasintha, omwe amawalola kuti ayang'ane madera akuluakulu ndikugwira nyama zomwe zikuyenda.
Kubereka ndi chiyembekezo chamoyo wa narwhal
Kuberekana m'zinyama izi kumachedwa. Amakhwima pogonana akafika zaka zisanu. Pakadutsa zaka zitatu pakati pa kubadwa. Nthawi yokwatirana ndi masika. Mimba imakhala miyezi 15.3. Monga lamulo, ma unicorn achikazi amabereka mwana wamphongo mmodzi, osowa kawiri. Zitsamba ndi zazikulu kukula, kutalika kwake ndi pafupifupi 1.5 mita.
Pambuyo pobereka, akazi amaphatikizidwa kukhala gulu losiyana (anthu 10-15). Amuna amakhala pagulu losiyana (anthu 10-12). Kutalika kwa mkaka wa m'mawere sikudziwika kwenikweni kwa asayansi. Koma amaganiza kuti, monga belugas, ili pafupifupi miyezi 20. Kuphatikiza kumachitika m'mimba mpaka m'mimba. Ana amabadwa mchira poyamba.
Narwhal Ndi nyama yokonda ufulu. Muufulu, amadziwika ndi moyo wautali, pafupifupi zaka 55. Sakhala mu ukapolo. Narwhal imayamba kufota ndikufa m'milungu ingapo. Kutalika kwakutali kwa narwhal mu ukapolo kunali miyezi inayi. Ma Narwhal samaberekerana mu ukapolo.
