A wolf pack is normally made up of anything from six to ten members.Unexpectedly, however, one can encounter packs of fifteen wolves and even more! Packs can be of various sizes depending on a number of factors, such as the availability of prey, the nature of the land--and, in some cases, man. The relationships within the pack are geared to a complex hierarchical structure, with leadership shared between its alpha male and female.This interesting social structure makes it unlike any other animal on earth even.
