Caption: Water flea feeding. Light microscope footage of a water flea (Daphnia sp.) feeding. Daphnia are small freshwater planktonic crustaceans. They feed on algae, bacteria and other organic detritus. The beating thoracopods (appendages) within the carapace create a current which draws food particles into the digestive tract. Prominent here are the compound eye (black area, upper right) and the gut (green) with food particles. Above the gut, the heart beats rapidly. Daphnia are around one millimetre in length and their transparent bodies have made them a popular subject for microscopy and physiological studies.
