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.

A 40-tonne humpback launching out of the water in an incredible breach in New South Wales, Australia on October 2022 in front of a sunset. The humpback whale can grow up to 56 feet long and typically covers 9,900 miles a year as it travels through the oceans of the world. Humpback whales are a species of Baleen whale, meaning they don't have teeth. Instead, they have baleen which helps them to filter feed. Their main source of food is krill or tiny bait fish.
