Arctic Wolf (Canis lupus arctos)  – (Pockock 1935)

Common Names: Melville Island Wolf, Polar Wolf, Barren-Ground Wolf

Overall population: Unknown, least concern in terms of population stability except in Greenland.

Physical description:
The Arctic Wolf is almost pure white with tinges of yellow, grey and black coloring in its fur. The fur coat has two layers; the under layer providing warmth and waterproofing and an outer layer that thickens in winter to guard against the subzero temperatures. Arctic wolves have proportionally smaller ears to help retain body heat. They have padded feet adapted to grip frozen ground and ice. Arctic wolves can have brown eyes/irises.

Range:
Original Range – “throughout the northern hemisphere north of 15°N latitude”
Current range – CAA, High Arctic, Melville Island to Ellesmere Island.
“The arctic wolf lives in the area along the northern edge of the North American continent and northward to the North Pole, as well as along the eastern and northern shores of Greenland.” (Arctic Wolves and Their Prey, L. David Mech, US Geological Survey, NOAA) 

Habitat / Ecology / Prey:
Habitat frozen tundra

Prey – ,Peary caribou (Rangifer tarandus pearyi), Muskoxen (Ovibos moschatus; Inuktitut: ᐅᒥᖕᒪᒃ, umingmak), Arctic hare (Lepus arcticus), Lemmings (Dicrostonyx groenlandicus), Arctic Fox (Vulpes lagopus), Snow Goose (Anser caerulescens), Arctic Ground Squirrel (Spermophilus parryii) (Urocitellus parryii)
