Facts about the Gray Wolves
•Adult gray wolves have 42 teeth, compared to 32 teeth for adult humans.
• The paws of a 60-pound wolf are the same paw size as some 100-pound domestic dogs.
•The wolf has powerful jaws to bite its prey and a very good sense of sight, smell and hearing.
• Wolves feed mainly on large mammals, including moose, caribou, elk, musk ox, bison and deer. They pick on a sick or weak animal that cannot keep up with the others. This may sound cruel but it's nature's way of building a strong ecosystem.
•
Wolves hunt in packs. They can not run as fast as a moose or deer. The wolves circle their prey and then attack.
