Indawo engokwemvelo esenyakatho yeplanethi yihlane lase-Arctic, elitholakala ebangeni lase-Arctic. Insimu lapha icishe imbozwe izinguzunga zeqhwa neqhwa, kwesinye isikhathi kutholakala izingcezu zamatshe. Lapha isikhathi esiningi sasebusika sibusa ngamakhaza ayi -50 degrees Celsius nangaphansi. Akukho ukushintsha kwezinkathi zonyaka, yize phakathi nosuku lwe-polar kunehlobo elifushane, futhi izinga lokushisa ngalesi sikhathi lifinyelela kuma-zero degrees ngaphandle kokunyuka ngaphezu kwaleli nani. Ehlobo kungana imvula neqhwa, kunenkungu eminyene. Kukhona nezimbali ezimbi kakhulu.
Ngenxa yezimo zezulu ezinjalo, izilwane ze-Arctic latitudes zinamazinga aphezulu okuzivumelanisa nale ndawo, ngakho-ke ziyakwazi ukusinda ezimweni zezulu ezinzima.
Iziphi izinyoni ezihlala ezingwadule zase-arctic?
Izinyoni zingabamele abaningi kakhulu bezilwane ezihlala endaweni eyihlane ye-arctic. Kunabantu abaningi bama-rose gulls nama-guillemots, azizwa ekhululekile e-Arctic.

Lokhu kuvikela izilwane emakhazeni amakhulu. Izinyoni ezibandayo zinezimpaphe ezixegayo ezihambisana kahle nomzimba. Ezimpawu zamanzi nezinye izilwane zasolwandle, ungqimba olunamafutha lwenzeka ngaphakathi emzimbeni, oluvikela emakhazeni. Izindlela zokuvikela ezilwaneni zisebenza kakhulu lapho kufika ubusika, lapho isithwathwa sifinyelela ubuncane impela. Ukuze bazivikele ezilwaneni ezidla ezinye, abanye abamele izilwane bashintsha umbala woboya bazo.
