Humpback Whales’ Global Circuit
Humpback whales split their lives between two very different worlds. When winter approaches, they swim thousands of miles to tropical breeding grounds where they fast for months while focusing on mating and giving birth. Adult humpbacks swim about 6,000 miles each way, but it’s the calves that really impress. These youngsters, just months old, must keep pace with their mothers on the return journey while learning to breach, dive, and avoid predators.
