Kunja ofanana kwambiri beluga narwhal. Koma kusiyana ndi nyanga yaikulu. Nthawi zambiri ilo likutchedwa tusk. Lalikulu ndi lamphamvu mapangidwe kutalika mamita 2-3 ndi kulemera kwa makilogalamu 10. Tusks amatha kukhotetsa mu madera osiyana pa nthawi yomweyo popanda kuswa.

narwhal nyanga Kodi

tusk ntchito akadali asanamvetsetse. Komabe, asayansi amati lero motsimikiza kuti si anaikira kuboola ayezi kutumphuka kapena kuukira wovulalayo.

Izo poyamba analengeza lomwe nyama amagwiritsa nyanga zake narwhal pachibwenzi - kuti kukopa zazikazi. Izo zinali zochokera kuzipenya. Popeza kuti nyengo mating nyama chimphona kwenikweni amakhala anakumana ndi tusks ake.

Mu 2005, ulendo sayansi, kusunga moyo narwhal, anazindikira kuti maphunzirowo ankaganizira kwambiri. Pophunzira nambala yake yaikulu molekezera mitsempha padziko zace wakhala wapezeka.

Asayansi aona kamodzinso mmene wapadera narwhal (nyama). Kuyeza kutentha ndi pafupipafupi mu atomu mafunde tusk - Baibulo wotsatira wa ikupita.

Hypersensitivity tusk

Narwhal nyanga akulemekezedwa ndi kumukonda wamtengo wapatali mu zikhalidwe zosiyanasiyana - zingakhale chokongoletsera nyumba yachifumu ndi mipando. Mu England, ndi tusk narwhal anakhala ndodo yachifumu. Koroleva Elizaveta pa tusk wa kumpoto chiphona analipira m'zaka XVI, ndalama wosangalatsa kwa nthawi zimenezo - mapaundi 10 chikwi. Ndi ndalama zimenezi, inu mukhoza kumanga nyumba yachifumu. ndondomeko zophweka ndi chiyani?

Narwhals ndi ochepa ndi suborder wa otchedwa zinsomba imodzi. Ngakhale izi, iwo kwenikweni - kukhala mano. Pa m'munsi nsagwada mano si konse, ndi pamwamba pali awiri okha nyongolosi. Mu pups akhoza kukhala awiriawiri sikisi chapamwamba ndipo mano m'munsi angapo, koma akhumudwa, ndipo m'malo mwa dzino anasiya amuna iyamba kukhala tusk, imene pa nthawi ya kukhwima wa nyama ukufika mamita 2-3 m'litali, 7-10 masentimita makulidwe, ndipo zambiri 10 makilogalamu kulemera. Long tusks kukongoletsa amuna okha. Nyanga wamkazi molunjika ndi yankholi. kawirikawiri, koma zimachitika kuti akazi onse dzino akusinthika mu tusks; ndi amuna adasiya canine amakhala nyanga, koma izi n'zochepa kuchotserapo.

Tusk anakudzula padziko ake ali mwauzimu struychatost (kudula), amene kumawonjezera kwambiri mphamvu yake. ulusi Izi kumeneko kwa nthawi yaitali: pamene akupita patsogolo wa tusk ndi nyama, kugonjetsa kukana amphamvu madzi, pang'onopang'ono imazungulira padziko olamulira yake. Chifukwa, una khoma Kadulidwa grooves mwauzimu anapanga pamwamba pake.

amuna chosowa kwambiri ndi tusks awiri, omwe anapangidwa kwa mano awiri. Malinga ndi kafukufuku, nyama zimenezi zimapezeka wina pa akulu 500.

N'zosadabwitsa kuti ngakhale nyama anakudzula lero, ndipo makamaka nyanga zake, kukhala chinsinsi chachikulu kwa asayansi padziko lonse. Iye bwino anamvetsa.

Pakali pano, ofufuza amakhulupirira kuti tusk narwhal limakupatsani kuona kusintha kutentha, kuthamanga, ambiri particles inaimitsidwa.

njira ya moyo

Narwhal - nyama (chithunzi ife anaika m'nkhani ino), omwe m'nyengo yozizira kumizidwa kuti akuya 1.5 Km. Izi ndi zofunika kuti adziteteze ku achisanu madzi Arctic. Patapita nthawi, iye limatuluka pamwamba pa mlengalenga ndipo kachiwiri zipita kozama. Masana, akupanga 15 imadumphira m'madzimo uku ikukupiza amenewa. Komanso, chitetezo chodalirika kwa ozizira pa blubber narwhal. wosanjikiza ake nthawi zina kuposa 10 cm. M'nthawi ya chilimwe nyama zambiri ili pa akuya 30 mpaka 300 m.

chakudya

banja

Animal narwhal akhoza kukhala nokha kapena magulu ang'ono ang'ono, chomwe 10 amuna achikulire kapena akazi ndi ana.

Poyamba, zimphona izi analenga ng'ombe lalikulu analipo mazana angapo, ndipo nthawizina zikwi nyama. Today n'kovuta kupeza gulu la atsogoleri oposa zana. Nthawi zina limodzi ndi chinsomba woyera.

Monga m'madzi zimakhala ena azikaweta nyama kulankhulana ndi wina vocalizations ena ntchito. Nthawi zambiri ndi phokoso lakuthwa ngati likhwelu, kulira, kudina, moo, gurgling squeaks.

kubalana

Mating akupezeka masika. Gestation kumatenga miyezi 14, zonse kubalana mkombero ndi zaka 2-3. Kawirikawiri chibala wina, makamakanso ana awiri. pamsinkhu wobereka kwa zaka 7. Milandu kuswana nyama mu ukapolo zalembedwa.

Manesi wamkazi wa ng'ombe ndi mafuta kwambiri mkaka miyezi 20.

Moyo mu ukapolo

Madzi chipembere amatanthauza yaing'ono gulu la nyama, zomwe sadzalekerera ukapolo. Izi zikuonekera bwino ndi mfundo wosatsutsika wakuti miyezi yoposa isanu m'ndende kuti sanapulumuke nyama iliyonse pamene mu chilengedwe iwo moyo mpaka zaka 55. Chiŵerengero cha narwhals si okhazikika, koma iwo ali ochepa, mitundu osowa, amene kale zidalembedwa Red Book of Russia.

Ndi chidaliro chonse angatchedwe cimodzi za zozizwa za Arctic, yekha ndi wapadera mu mtundu wake.

malo

Tanena kale kuti nyama zamphamvu moyo mu climes nkhanza kumpoto. Ambiri mwa nyanja Arctic mu Ocean Arctic. Narwhals angapezeke kuchokera Greenland, komanso mbali ya kumpoto Canada Arctic Archipelago.

magulu ang'onoang'ono mayina a kumpoto cha kum'mawa kwa Franz Josef Land, ndi chosowa kwambiri - pakati pa Kolyma ndi Cape Barrow. Ichi ndi chifukwa chosowa chakudya - pali cephalopods pang'ono. "Pole North" anawerengedwa gulu narwhals kumpoto kwa Wrangel Island. Iwo amakhala mu madzi ozizira m'mbali mwa kozizira ayezi, kupanga migrations nyengo: m'chilimwe - kumpoto, ndipo m'nyengo yozizira - kum'mwera.

Nyama madzi unicorns kudya anthu a kumpoto. Amagwiritsa ntchito mafuta a nyama monga njira nyali (chingwe). Matumbo ntchito zingwe kupanga, twines. Koma wofunika kwambiri ndi nyanga mwachinsinsi kapena tusk. Kuyambira amisiri ili kumpoto anapanga zamanja zosiyanasiyana.

anthu

Animal narwhal - mitundu malochislenny pafupi kutha. Mu Ages chifukwa cha nyanga zake, limene, mogwirizana ndi asing'anga, ali ndi mphamvu zamatsenga Middle, nyama izi anawononga lalikulu zedi.

Ngakhale lero, ndi tusk zachilendo zikhoza kupha nyama. Iwo ankasakidwa Eskimos. Ngati kusaka mu masiku akale ntchito dzanja ankaweruza harpoons, lero ntchito motorboats ndi zipangizo zodziwikiratu kwa narwhals kupha.

Aliyense amene dzanja lake nyama zimenezi sizichitikachitika, muyenera kudziwa kuti zizindikiro za topezeka wamoyo, akuona kusintha kwa nyengo pang'ono, tcheru ndi kuwonongeka kwa malo.
