Factors Influencing Weight:
* Sex: Male wolves are generally larger and heavier than females.
* Age: Wolf pups start small and gain weight rapidly until reaching maturity around 2-3 years old. Older wolves may lose weight.
* Geographic Location: Wolves in colder climates tend to be larger than those in warmer climates.
* Food Availability: Wolves in areas with abundant prey may be heavier than those in areas with limited food.
Examples:
* A large male gray wolf in Alaska can weigh over 175 pounds.
* A female gray wolf in the eastern United States might weigh around 80 pounds.
* An Ethiopian wolf, the smallest wolf species, might only weigh 30 pounds.
