Wolves can be very different from each other.
Some are larger and more powerful than others. Some have more fur on their bodies, or thicker capes of fur on their backs. And there is an almost incredible variety in the colors and patterns of fur, as you can see above. When it comes to fur, every wolf seems to be different from every other wolf. And these differences can sometimes be used to tell one wolf from another - in the same way that people look at human faces to tell one person from another.
