A day when the sea is as calm as a lake without a ripple, so much calm that we can easily zoom our eyes through the thin water and see the humpback whale mother and calf gliding gently beneath the surface. The moment when the mother whale's tail is hidden in the water as it glides across the calm sea, but accidentally splits the water into the shape of another tail that is even bigger and more splendid, created by sunlight, waves, sponges and a little bit of ocean poetry.
