The Hydra is an ancient serpentine marine monster, a fearsome beast in Greek mythology who grew two heads for each one removed by a valiant warrior. Its real life equivalent, a freshwater polyp no longer than a centimeter (0.4 inches), is far less frightening but still quite remarkable – it is able to regenerate its entire body from any tiny fragment of itself.
