A study visualizing the fluid flow around 15 species of unicellular flagellated protists, which use their flagella to generate currents that enable feeding while avoiding detection by flow-sensing predators, finds that the arrangement of flagella governs swimming speed, architecture of the fluid flow, and the trade-off between feeding and predator avoidance, with the dinoflagellates achieving particularly successful feeding and stealth behavior due to their unique flagellar arrangement.
