Wolves in packs

It is well known that wolves are pack creature`s, and normally lone wolves  don`t live much longer after leaving the pack. Each pack has ranking`s. they go from omega to alpha in the middle and second in command, Beta. The Alpha is the leader of the pack, and can be challenged by any wolf no matter what rank they may be. Wolf packs can get up to about 30 wolves. The Omega of the pack is always the last to eat, Which is why it is the skinniest. It always approaches the meal with its tail between its legs.
