2020 Small World in Motion Competition

Two larvae of parasitic flatworm are captured here, seemingly interacting in what might be arguably displayed as complex interactive behavior between the two creatures. It brings to light the fact that, albiet it rare, complex interactions between microscopic creatures do exist. Capturing this wonderful exchange between the two organisms is especially difficult since Mr. Martin Ledo needed to use extreme care when isolating them to assure they are not damaged or change their morphology. This movie was captured using phase contrast microscopy.
