One source of scent is urine, which they use to mark territory and to tell other wolves in their own pack where they are. Another way wolves communicate is through body language. If a wolf feels confident, it will approach another wolf with its head and tail held high and ears perked up. If you saw a wolf slinking toward another with its body lowered, its tail between its legs, and its ears flattened, you'd know it was approaching a dominant animal. When a wolf wants to play, it prances about happily and bows lowering the front of its body while its rump stays up in the air with its tail wagging. When its angry, a wolf may furrow its forehead, show its fangs, or growl. A wolf's body language may remind you of another animal: a pet dog. Wolves and dogs are closely related, and the ways they communicate are similar.

Gray wolves, or timber wolves, are canines with long bushy tails that are often black-tipped. Their coat color is typically a mix of gray and brown with buffy facial markings and undersides, but the color can vary from solid white to brown or black. Gray wolves look somewhat like a large German shepherd.Physical description. Keen senses, large canine teeth, powerful jaws, and the ability to pursue prey at 60 km (37 miles) per hour equip the gray wolf well for a predatory way of life. A typical northern male may be about 2 metres (6.6 feet) long, including the bushy half-metre-long tail.Wolves have many unique abilities that other animals do not have. Most abilities are useful, such as their teeth. Their teeth are perfect for puncturing and slashing fish, picking meat off of bones, and their premolars and rear molars are capable of breaking bones (CITE).

The U.S. Fish and Wildlife Service officially removed the wolf from the endangered species list last week. Because the Northern Rockies and Great Lakes populations have rebounded, the agency claims, gray wolves no longer warrant protection under the law.Wolves are threatened by conflict with humans and intolerance, and the loss of both habitat and protections under state and federal endangered species laws. The gray wolf is endangered in many parts of its historic range, but delisted (by Congress) in much of the Northern Rockies3 Fish and Wildlife Service order removed gray wolves from the endangered species list in all of the lower 48 states, mostly affecting the Great Lakes region. Wolves in the Northern Rocky Mountains had already been delisted federally. A Wisconsin judge ruled in February that state law required a wolf hunting season.

.The jaws of a wolf are extremely powerful, and the wolf has a biting capacity of between 1,000 and 1,500 pounds per square inch. Gray wolves were hunted nearly to extinction in the continental U.S. due to the threats they posed to human safety and livestock. The Eurasian wolf (Canis lupus lupus) is the powerful, most fiercesome wolf species ever walked on land.

Gray wolves are considered to be elegant predators and highly social animals that form tight, nuclear packs. A symbol of the wilderness and the predecessors to our domesticated dogs, these majestic creatures are still plentiful in rural areas all over the world.Wolves are the largest members of the dog family. Wolves are legendary because of their spine-tingling howl, which they use to communicate. A lone wolf howls to attract the attention of his pack, while communal howls may send territorial messages from one pack to another. Some howls are confrontational.
