A whale of a hug
This time of year, humpback whales make their annual trip to the warm waters of the South Pacific to mate. Today's image finds us swimming alongside a humpback mother and her young calf near the Polynesian island chain of Tonga. The humpbacks return each year from their feeding grounds off Antarctica—a journey of more than 6,400-kilometres. Through November, the cows will stay in this region while their newborn calves grow strong enough to make the trek back to the cold Antarctic waters where their main food source—the small crustacean called krill—is abundant. Humpbacks are found in every ocean in the world. They’re known for their magical songs, which like the humpback itself, can travel great distances through the water. Scientists are still studying these sounds to find out what they mean. But it's likely they sing to communicate with others and attract potential mates. Or maybe it’s a way to pass the time on that 6,400-kilometre journey through the oceans.
