If lifespan is defined as the entire lifetime of an animal from birth until death, then the record for shortest average lifespan belongs to a group of microscopic worm-like animals called gastrotrichs.Continue Reading
The entire life cycle of a gastrotrich only lasts three or four days. There are many varieties of these aquatic microorganisms, but none live more than a few days under normal circumstances. This life is spent floating about, eating and reproducing. For some gastrotrichs, reproduction involves an exchange of genetic material with another individual, but many species reproduce by parthenogenesis, in which the offspring is a genetic copy of the adult animal.
