Snapshots of vorticity heatmaps capture the complex, time-varying flow structures generated by simulated oscillatory flow over multiscale reef topography. Coral larvae pathlines from an agent-based model show the interaction of swimming larvae with these flow structures, causing them to dance and spin as they make their way to their new home on the benthic surface.
