Fluid Flow Around a Microbe (image) American Physical Society Caption Researchers have mapped the flow field around a swimming Volvox carteri microbe by tracking the movements of tiny tracer particles. The spherical Volvox is swimming towards the top of the image. Streamlines appear as red curves, and the color map corresponds to the fluid velocity. Credit K. Drescher, R. E. Goldstein, N.
