Wolf

Wolf (Canis lupus), powerful carnivore ranging throughout the deciduous and coniferous forests and tundra of the Northern Hemisphere. Broad-chested, with small, pointed ears and long legs, wolves are pack hunters, preying on the huge northern moose, deer, and elk herds. In the summer, with the onset of the breeding season and with small-mammal prey more readily available, the packs break up into smaller groups. Wolf packs have distinct territories, and within the pack there is a complex social structure under a top male and female.
