While not always the case, large whales (particularly those that belong to the baleen whale suborder) tend to live more solitary lives and are more likely to travel alone or in small temporary pods. Lastly, smaller species of whale and other cetaceans are known to form pods or large communities, which increase social interaction among marine mammals and help deter large predators or minimize the chance of any single animal being harmed as they all belong to the group.
