ArcticWolf

`这种狼仅仅只会长到3英尺高.北极狼吃驼鹿、鱼类、北极熊和兔子。它们用林子里的灰色、绿色和褐色作为掩护，北极狼有着一层厚厚的毛，它们的牙齿非常尖利，这有助于它们捕杀猎物。生活在从加拿大的拉布拉多地区到英国的哥伦比亚地区，它们不迁徙，也不冬眠。但是由于由于人类的采伐树木、污染和垃圾，它们失去了它们居住的地方。每年至少有196只北极狼死去。Thisisonlythewolfsheadtojust3feethigh.Arcticwolveseatmoose,fish,polarbearsandrabbits.Theyusethewoodsofgray,greenandbrownasacover,theArcticwolfhasathicklayerofhair,theirteethareverysharp,whichhelpsthemtokilltheirprey.LivingintheLabradorregionfromCanadatotheBritisharea,theydonotmigrateorhibernate.However,duetohumanharvesting,pollutionandwaste,theyhavelosttheirplacetolive.Everyyearatleast196died.
