Cyclops are tiny crustaceans of the family Cyclopidae, also called water fleas. They are usually found in stagnant bodies of fresh water such as wells and ponds in poor agricultural communities in rural or periurban areas. Cyclops are just visible (0.5–2 mm) and can be recognized by their jerky mode of swimming. They feed on plankton and other small aquatic organisms. Their life cycle is adapted to their natural habitat in ponds and other accumulations of stagnant water.
