Chigawo chakumpoto kwambiri padziko lapansi ndi chipululu cha Arctic, chomwe chili kumpoto kwa Arctic. Gawo ili pano laphimbidwa ndi matalala ndi chipale chofewa, nthawi zina zidutswa zamiyala zimapezeka. Apa nthawi zambiri nthawi yachisanu imalamulira ndi chisanu cha -50 madigiri Celsius ndi pansipa. Palibe kusintha kwa nyengo, ngakhale mkati mwa tsiku la polar kuli chilimwe chachifupi, ndipo kutentha panthawiyi kumafika madigiri a zero, osakwera pamwambapa. M'nyengo yotentha imatha kugwa ndi matalala, kuli nkhungu zowirira. Palinso maluwa osauka kwambiri.
Pogwirizana ndi nyengo zoterezi, nyama zakunyanja ya Arctic zimakhala ndimalo oterewa, kotero zimatha kupulumuka nyengo yovuta.
Ndi mbalame ziti zomwe zimakhala m'chipululu cha arctic?
Mbalame ndizoimira nyama zambiri zomwe zimakhala m'chipululu. Pali mitundu yambiri yamaluwa ndi ma guillemots, omwe amakhala omasuka ku Arctic. Bakha wakumpoto, wakudya wamba, amapezekanso pano. Mbalame yayikulu kwambiri ndi kadzidzi wakumpoto, yemwe samasaka mbalame zina zokha, koma nyama zazing'ono ndi nyama zazikulu zazing'ono.

Kodi ndi nyama ziti zomwe zimapezeka ku Arctic?
Pakati pa nyama za cetaceans zomwe zili m'chipululu cha Arctic, pali narwhal, yomwe ili ndi nyanga yayitali, ndipo m'bale wake ndi anangumi. Komanso, pano pali anthu a dolphins a polar - anamgumi a beluga - nyama zazikulu zomwe zimadyetsa nsomba. Ngakhale m'mapululu a arctic, anamgumi akupha amapezeka akusaka nyama zosiyanasiyana zakumpoto.
Nsomba ya Bowhead
Pali zisindikizo zambiri m'chipululu cha Arctic, kuphatikiza zisindikizo za zeze, zisindikizo zoyenda mozungulira, zisindikizo zazikulu zam'madzi - zisindikizo, kutalika kwa mita 2.5. Ngakhale m'dera lalikulu la Arctic, mutha kupeza ma walrus - nyama zolusa zomwe zimasaka nyama zing'onozing'ono.
Chisindikizo cholumikizidwa
Mwa nyama zapamtunda zomwe zili m'chipululu cha arctic, zimbalangondo zakumtunda zimakhala. M'derali, ndi akatswiri posaka pamtunda komanso m'madzi, chifukwa amathamangira ndikusambira bwino, zomwe zimawalola kudyetsa nyama zam'madzi.
Zimbalangondo zoyera
Chilombo china cholusa kwambiri ndi nkhandwe, yomwe simapezeka mwapadera m'dera lino, koma imakhala paketi.
Nkhandwe ya ku Arctic
Nyama yaying'ono ngati nkhandwe ya Arctic imakhala pano, yomwe imayenera kuyenda kwambiri. Lemming imapezeka pakati pa makoswe. Ndipo, kumene, pali anthu ambiri a mphalapala pano.

Kusinthitsa zinyama nyengo yayitali
Mitundu yonse yomwe ili pamwambapa ya nyama ndi mbalame yasinthira moyo wam'mlengalenga. Apanga maluso apadera osinthira. Vuto lalikulu pano ndikutentha, kotero kuti nyama zikhale ndi moyo, ziyenera kuwongolera kutentha kwake. Zimbalangondo ndi nkhandwe ku Arctic zili ndi ubweya wakuda chifukwa cha izi. Izi zimateteza nyama ku chisanu choopsa. Mbalame zam'madzi zimakhala ndi nthenga zosasunthika zomwe zimagwirizana bwino ndi thupi. M'zisindikizo ndi nyama zina zam'madzi, mafuta amapangika mkati mwa thupi, omwe amateteza kuzizira. Njira zotetezera nyama zimagwira ntchito makamaka nthawi yozizira ikamayandikira, pomwe chisanu chimakhala chochepa kwambiri. Pofuna kudziteteza kwa adani, oimira zinyama zina amasintha utoto waubweya wawo. Izi zimalola mitundu ina ya nyama kubisala kwa adani, pomwe ina imatha kusaka bwino kuti idyetse ana awo.
Anthu odabwitsa kwambiri ku Arctic
Malinga ndi anthu ambiri, nyama yodabwitsa kwambiri ku Arctic ndi narwhal. Ichi ndi chiweto chachikulu chomwe chimalemera matani 1.5. Kutalika kwake kumakhala mpaka 5 mita. Nyama iyi ili ndi nyanga yayitali pakamwa pake, koma kwenikweni ndi dzino lomwe silimagwira ntchito iliyonse pamoyo.
M'madamu a Arctic pali dolphin ya polar - beluga. Amangodya nsomba. Pano mutha kukumananso ndi chinsomba chakupha, chomwe ndi chilombo chowopsa chomwe sichinyalanyaza nsomba kapena nyama zazikulu zam'madzi. Zisindikizo zimakhala m'chipululu. Miyendo ndi mapiko awo. Ngati pamtunda zimawoneka zovuta, ndiye m'madzi zikuluzikulu zimathandizira nyamazo kuti ziziyenda mwachangu kwambiri, kubisalira adani. Achibale a zisindikizo ndi ma walrus. Amakhalanso padziko lapansi komanso m'madzi.
Chikhalidwe cha Arctic ndichodabwitsa, koma chifukwa cha nyengo yovuta, sikuti anthu onse akufuna kulowa mdziko lino.
