Tundra Wolves have a mixed color coat of whites, greys, and browns that covers the entire animal, including the snout. Their fur is thick, long, and dense. Wolves' eyes are circular in shape with multiple different colors ranging from dark brown to light blue. They have black noses, white whiskers, and dark brown inner ears. They have light underbellies. 

Wolves have many adaptations that allow them to mark territory, hunt successfully, and mate successfully. Body language, scent marking, growling, and howling allow them to communicate. They also have smaller ears and noses, extra body fat, and thicker fur coats. Wolves travel in packs that often have two to fifteen members. Packs travel together, sleep together, and hunt together with a male wolf as the dominant leader. Young stay in the pack for three years until they decide to either leave the pack or officially join the pack. Wolves mate for life, breeding from January to March. Female wolves are pregnant for an average of 63 days and usually create 6 offspring. 

Wolves are the largest living wild canine species. They are the wild ancestor of all species of domesticated dogs. Wolves can reach speeds of up to 40 miles an hour. Their long legs are well-adapted for running, catching prey, and traveling far in search of game.
