Most tooth whales travel in group or pods, some number up to over a hundred. Baleen whales travel in pods or gams made up of family units. Migration for baleen whales includes a lengthy trip each year. Their requirement for high densities of food causes this migration. Whales have been found to be intelligent.
Echolocation is the primary source used to locate food and to guide it toward or away from objects.
Migrating Bowhead whales are guided around ice by scout whales traveling miles far ahead of the pod. Humans have interacted with whales for centuries. First with whaling and now with research. Some whales are naturally curious. The Mink whale has been know to approach a boat to within 20 to 30 yards.
