Arctic Wolf (Canis lupus arctos) – (Pockock 1935)
Common Names: Melville Island 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.
Original range – Canadian Arctic Archipelago,
Current range – Melville Island to Ellesmere Island
