The mesmerising stare of a gray Wolf

Gray wolves communicate to each other through howling, body language and scent. Howling is used to assemble the pack, talk to other packs, assert territorial claims or as a source of pleasure. On a calm night, howls can be heard from as far as 120 miles away. Wolves use their faces and tails to indicate their emotion and status in the pack. A pack marks its territory by urine and feces.
