In recent decades, the Yangtze River dolphin or baiji （Lipotes vexillifer） gradually declined while the world stood by. Wildlife biologists, conservationists, and government officials discussed the merits of protecting the species in the wild versus moving the remaining individuals to a nearby lake （Yang et al., 2006; Reeves ＆ Gales, 2006; Wang et al., 2006）, but did neither. The baiji＇ s Yangtze River habitat has become increasingly inhospitable from over-fishing, pollution, dams, boat traffic, and poaching; a few attempts to breed captive baiji have failed. In the end, the baiji declined from thousands to tens, and finally, according to a recent survey （baiji. org/） there are no more left. If any baiji remain in the Yangtze, there are too few to maintain a viable population. In losing the baiji, China lost an important cultural symbol and the world has lost a unique species tens of millions of years old and the only member of its entire family.
