Regarding the Gray Wolf, its' size and its' tendencies here in the US. 25) How big are wolves?

The size of a wolf varies depending on where it is found. Smaller sizes tend to be found in the southern portion of wolf range and larger sizes in the northern portion. Females tend to be slightly smaller than males. The average size of males is 5 to 6.5 feet long (tip of nose to tip of tail), 26 to 32 inches high at the shoulder, and 70 to 115 pounds in weight (in Alaska they occasionally reach 145 pounds). The average size of females is 4.5 to 6 feet long, 26 to 32 inches high at the shoulder, and 60 to 100 pounds in weight. Wolves reach adult size by 1 year of age. 8 Do wolves really take the old, young, sick, starving, or injured animals? It is well-documented that wolves tend to do this. Hunting and bringing down big game is dangerous work and wolves are sometimes killed by elk, moose, and even deer. In the wild, they cannot afford to be injured; therefore, they go after the safest animals to kill and often leave strong animals alone. A recent study of wolf predation on elk in Yellowstone National Park, for example, found that wolves tend to kill calves and older animals – adult elk killed by wolves were about 7 years older than elk killed by hunters. If weather or other conditions make prey unusually vulnerable, wolves can and do kill prime-aged animals but wolf predation tends to be selective. http://www.fws.gov/midwest/wolf/biology/qandas.htm
