Madaxkuti cidhif ee ku nool wadanka Alaska.

Madaxkuti cidhif (Af Ingiriis : polar bear; Af Ingiriis : Ursus maritimus;) nooca ugu weyn ee madaxkuti ah oo ku nool goobta cidhif (Arctic), gaar ahaan agagaarka Cirifka waqooyi. Madaxkuti cidhif waxay si gaar ah ugu habboon yihiin inay ku noolaadaan deegaan qabow oo baraf leh. Furuugooda dhumucdiisuna waxay bixisaa diiranaysi ka dhan ah qabowga daran, waxaana hoostiisa jirkooda ku yaal maqaarka madow ee ka caawiya inuu nuugo oo ilaaliyo kulaylka qorraxda. In kasta oo furuugoodu muuqdo caddaan, taasoo ka caawisa inay ku milmaan barafka, dhab ahaantii waa mid aan midab lahayn. Madaxkutiga cidhifka waa hilibcunaha ugu waaweyn ee dhulka ku nool, iyadoo labadooda ragga weyn ay miisaankoodu gaarayo ilaa 1,500 rodol (680 kg) iyo dhererka ay gaaraan qiyaastii 3 meter marka ay taagan yihiin lugahooda dambe.[1]

Cuntohoodu waxay inta badan ka koobantahay seal-ka, gaar ahaan noocyada ringed iyo "bearded seals", kuwaas oo ay ku qabsadaan iyadoo ay sugaan meelaha ay sealku ka soo baxaan si ay neefsadaan. Waa dabaal-qaboojiye aad u xirfad leh waxayna awoodaan inay masaafoyin dheer ku dabaalan karaan badda furan marka barafka badda uu yaraado. Madaxkutiga cidhifka waxay inta badan ku tiirsan yihiin barafka badda ee ay ku ugaarsadaan, safraan, isla markaana ku tarmaan. Si kastaba ha ahaatee, isbeddelka cimiladu wuxuu khatar weyn ku yahay badbaadadooda, maadaama kulaylka sareeya uu keeno in barafka Arctic uu dhaco, taasoo ku qasbaysa madaxkutiga cidhifka badeedka inay safar dheer sameeyaan oo saameyn ku yeelaneyso awooddooda inay ugaarsadaan iyo tarmaan. Dhibaatooyinkan awgood, madaxkutiga cidhifka badeedka waxaa loo tixgeliyaa kuwo nugul, waxaana socda dadaallo lagu ilaalinayo deegaanadooda iyo yareynta saameynta isbeddelka cimilada ee ku saabsan badbaadadooda.
