Physalia mikazuki sp. nov., a newly described Portuguese man-of-war filmed alive from Sendai Bay, Japan. The footage shows distinct clusters of zooids (feeding, reproductive, and defensive units) arranged beneath the translucent, crescent-shaped float. Their coordinated motion highlights the colony's intricate organization characteristic of the genus Physalia.
