They tend to live in the remote wilderness, though red wolves prefer to live in swamps, coastal prairies and forests.he most common type of wolf is the gray wolf, or timber wolf. Adult grey wolves are 4 to 6.56 feet (120 to 200centimeters) long and weigh about 40 to 175 pounds (18 to 79 kilograms). Just like its name, the gray wolf typically has thick gray fur, although pure white or all black variations exist.
