Wolves are mammals (stating the obvious). They live in groups called packs that can have from around 5-15+ members. There can be 30 members but usually between the numbers I said. Packs are most often a group of related wolves, like a couple of mates and their off-spring. Lone wolves may wander in and join the pack, but that is a risky thing to do as they may be killed… Wolf packs have different ranks in their packs. The most commonly used terms for these are alpha, beta and omega, then a bunch of other wolves, like pups, hunters etc. The alphas are the leaders of the pack and make decisions about what the wolves will do. The beta or betas (as there may be two but most likely one) Make sure all the wolves of the pack do their job correct, and also help decide if a lone wolf should join the pack. The omega or omegas are naturally suspicious/slightly paranoid. They are lookout wolves and also break up fights between pack members. Two small packs may join together, or a large pack may split into two packs.
