Isikhova esine-polar sibizwa nangokuthi isikhova esimhlophe. E-Arctic yisidalwa esidla ubhedu esikhulukazi. Kuyaziwa ukuthi izimpiko zesikhova esisezingeni eliphakeme zedlula amamitha elilodwa nesigamu. Isisindo sowesifazane sidlula amakhilogremu amathathu, futhi ngobude bungaba ngamasentimitha angamashumi ayisikhombisa. Abesilisa bancane kakhulu kunabesifazane.
Isendlalelo somoya esiyingqayizivele esinciphisa ukulahleka kokushisa endaweni yesikhova esisezingeni eliphakeme siyimpaphe enkulu emanzi engaqinile. Kungenxa yeplamu ukuthi isikhova sibonakale sikhulu. Konke ekubukekeni kwesikhova kuhlelwe ngendlela yokuthi kuvame ukubekezelela izimo zesimo sezulu esibuhlungu. Isibonelo, izimpaphe ebusweni bakhe zicishe zamboza ngokuphelele uqhwaku, zivikele ku-hypothermia. Izimpaphe zicishe zavaleka ngokuphelele ngezimpaphe, zimboza imichilo. Imvelo yanika isikhova ipulamu emhlophe, kangangokuba yacishe yabonakala eqhweni. Kodwa-ke, kubalulekile ukuphawula ukuthi abesilisa kuphela abanombala omhlophe omsulwa onama-inclusions amancane amnyama. Ngokuphambene nalokho, izintokazi zinesifuba esimhlophe nesisu, kanti phezulu imivimbo emnyama. Lolu hlobo lokuzifihla lenza insikazi icishe ingabonakali ekutshoneni kweqhwa elimhlophe. Ngaphezu kwalokho, le nyoni indiza ngokushesha okukhulu, yize kunjalo inezici ezihehayo. Imininingwane ebalulekile ukungabi nalutho kwendiza yesikhova. Konke lokhu kuhlangene kufaka isandla ekuzingeleni okuphumelela komzingeli we-Arctic. Kuyaziwa ukuthi isikhova esimhlophe sinokusabela okugcwele. Ngaphezu kwalokho, iso lesikhova likhethekile. Le nyoni ine-acuity ebonakalayo ephindwe kayishumi kunokomuntu. Lokhu kungenxa yokuthi le nyamazane ibona inyamazane ingagcini ekukhanyeni kwenyanga, kepha futhi nasekukhingeni kwezinkanyezi, lapho ubusuku bungabinayo inyanga. Ayikwazi ukuthwala ukukhanya okukhanyayo, isikhova sikhetha ukuzingela ebumnyameni. Yize zisesimweni se-Arctic, lezi zidla zingelwa nangosuku oluyindilinga.
Izikhova ze-Polar zidla emalimini, amagundane, amabala, amadada. Ngaphezu kwalokho, izisulu ezidla amaqanda namachwane ezinyoni ezincane. Ikakhulu lokhu kwenzeka kaningi lapho kukhona ama-lemmings ambalwa namagundane ku-tundra. Ngalesi sikhathi, izikhova zonakalisa izimakethe zezinyoni.
Phezu kokuthi iqiniso lokuthi isikhova esine-polar sihlala e-Arctic nase-Arctic, senzeka naseGreenland nase-Iceland. Ukuhlala endaweni evulekile, isikhova sikhetha izindawo ezinamadwala ezingatholakali izidleke. Ukuba izisulu ezidla ezinye, izikhova ziphila impilo eyedwa. Kodwa-ke, kanye ngonyaka - ngoMeyi, izikhova zihlukaniswe ngababili. Kukhona imibhangqwana enjalo isizini eyodwa, kuze kube yilapho amaphuphu esekhulile. Izikhova ezinemakhaza zihlela izidleke zazo emhlabathini phakathi kwamatshe. Ibopha isidleke phansi, insikazi ibekela amaqanda ayo lapho. Ababelethi abazalelwe ephasineli bondliwa ngamalambu. Kepha kaningi lokhu akwanele. Futhi ngenxa yalokho, amabalelana amancane namachwane amancane aba yizisulu. Ngalesi sizathu, zonke izinyoni ze-tundra aziziphathi izikhova ziye kumoya. Ama-goose kanye ne-eider kuphela awabesabi, ngoba izimpungushe ezibucayi aziveli eduze nezidleke zezikhova.
Ebusika, lapho ukudla kuba yindlala e-tundra, izikhova ziyaphoqeleka ukuthuthela eningizimu. Ama-rodings ahlukahlukene kanye nama hares aba yizisulu zezikhova ezinamakhaza endaweni eyihlathi-steppe. Njengoba i-omnivorous and dexterous, isikhova siyakwazi ukubamba izinhlanzi eziye zenyuka zaya ngaphezu kwamanzi zisuka ekujuleni.
