Humpback Whales

Most whales migrate to eat and breed. For example, baleen whales feed mostly on krill, which is abundant in very cold waters. However, these cold waters are not a suitable environment in which to give birth – newborn calves are born without a protective blubber layer under their skin and would quickly freeze to death. So whales meet their need for food and suitable calving areas by travelling long distances from cold feeding areas, to warm, shallower waters for calving and mating.
