Not all Orcas are the same. Orcas are divided in three main groups: Residents, Transients, and offshore.
Residents migrate relatively little, eat only fish and are smaller, Transients are bigger, migrate very long distances, eat mainly mammals but also other things. Pods of either group interact with other pods of the same group, but Transients and Residents always give each other a wide berth. They don't fight, they just don't interact at all. Genetic studies indicate there hasn't been cross-breeding in the wild between Residents and Transients in over 700.000 years (They have mated in captivity, however).
Offshore Orcas, as their name suggests, travel far from shore and feed primarily on schooling fish.
