During courtship, humpback whales (Megaptera novaeangliae) sometimes swim together in a graceful manner reminiscent of a choreographed performance, and take an interest in boats and people. The two whales pictured here are a good example. The closer whale is the male, while the darker whale in the background performing a spyhop is the female. I came across this pair outside the Hunga island area in Vava'u, Tonga.
