This is a male Leiaster leachi sea star broadcasting sperm into murky water in a shallow bay. Other nearby sea stars were broadcasting sperm and eggs into the water in synchrony, though the they were not within visual distance of one another. Over the course of an hour or more, the sea star swayed and twirled as it released streams of sperm—a five-limbed dancer gyrating to a silent, timeless rhythm of life. This individual was between 40cm and 45cm in diameter. Photographed in Kagoshima Prefecture, Japan.
