I was fortunate to have encountered a humpback whale with her calf on my first day snorkeling near Japan’s Kumejima Island. Most of the time, the calf stayed close to her mom. At one point, the calf began jumping and tapping its tail on the water near us—it was very friendly and curious. Finally, the mother, who was watching nearby, came to pick up the calf and swim away. I fell in love completely with the calf and its very energetic, large, and beautiful tail.
