Wintertime brings large numbers of humpback whales to the icy waters off the Norwegian coast, where they feed on herring and krill—and delight whale watchers with powerful leaps, tail-slaps, and glimpses into their underwater world. Male humpbacks are famous for their haunting songs, which can last up to 20 minutes and be heard over great distances underwater. Scientists aren"t sure why exactly the males sing these ballads, but some theorize it"s related to courtship. That sounds romantic enough, but ladies take note—the humpback isn"t one to settle down. It"s a migratory animal that swims up to 16,000 miles a year, traveling from southern breeding grounds to Arctic waters like these.
