Shooting star by Tony Wu, US/Japan. Winner, underwater. The electrifying reproductive dance of a giant sea star. As the surrounding water filled with sperm and eggs from spawning sea stars, Wu faced several challenges. Stuck in a small, enclosed bay with only a macro lens for photographing small subjects, he backed up to squeeze the undulating sea star into his field of view. The dancing posture of spawning sea stars rising and swaying may help release eggs and sperm, or may help sweep the eggs and sperm into the currents where they fertilise together in the water.

Winner. “This was taken in the South Ari Atolls, Maldives, as the south-west monsoon season was setting in. It features my partner – and dive buddy – Emma after surfacing at the end of the last dive of the day to find 1.5 metre swells and dark monsoon clouds. MICK RYAN, JUDGE: This beautiful portrait of a diver in an ocean swell below a menacing sky stands out this month for its emotional and elemental beauty. It is a reminder that while we may play among nature we are always dwarfed by its power and must be constantly on our guard”. (Photo by Simon Dunn/The Guardian)
