In all wolf packs there are ranks, each wolf has a job in the pack. The leaders are the alphas, the alpha male and alpha female. The alphas are the wolves that normally have the pups. The alphas are always confident and highly respected by the other wolves. The next important wolf is the beta. Betas look after the pups and makes sure other wolves listen to the alphas. Omegas often have to be last because they are the lowest ranking wolves in the pack. The other wolves in the pack don't have a rank and are simply the wolves that make up the rest of the pack.
Wolf packs are organized and do everything together. Wolves eat in the order that they are in the pack: alpha, beta, omega.
