a–c A chain swimmer chasing (a), encountering (b), and following (c) a chemical source (symbolized by a star) moving along a circular orbit. d–f Similar to a–c, but for a ring swimmer and a source executing a figure-eight-shaped path. g Trajectories of chain (left column) and ring (right column) swimmers pursuing a source at varying speeds. Source data are provided as a Source Data file.
