The gray wolf is the largest of the wild canines, averaging 80-145 lbs (40-70 kg). Wolves are social and will travel and hunt in packs. They are the top predator in areas they inhabit, outcompeting smaller canines, such as coyotes, who would be eating similar prey species.
Despite years of persecution, wolves are now recognized as a keystone species. Wolves keep the population of large herbivores in check, allowing for diverse plant species to flourish. This plant life provides food and shelter for many animals and can improve water quality in nearby streams and rivers.
