Extinct in the wild Extinct in the wild An extinct in the wild (EW) species is one which has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss. Examples of species and subspecies that are extinct in the wild include: The Pinta Island tortoise ("Geochelone nigra abingdoni") had only one living individual, named Lonesome George, until his death in June 2012.
