The Journey of the Freshwater
Water vapor rises high into the air and then falls on mountains and runs through valleys until it meets a river. You will meet many underwater creatures in a drop of water?s journey from river to ocean. In this programme, there are stories about carnivorous plants that lure and trap insects to get nutrition, the nematomorph hairworm which is a parasite on other insects' bodies and induces suicide, the mystery of the parasitic wasp which goes underwater inside the caddis fly larva to lay its eggs, and the sad life of the dayfly that lives only 8 hours above water to mate after 2-3 years of life underwater. Like endless running water, the river is always full of life.
