Caption: Water flea heart. Light microscope footage of the rapidly beating heart of a water flea (Daphnia sp.). Individual blood cells are seen circulating. Also visible is the digestive tract (green). Daphnia are small freshwater planktonic crustaceans. They feed on algae, bacteria and other organic detritus. Daphnia are around one millimetre in length and their transparent bodies have made them a popular subject for microscopy and physiological studies.
