THE YUNNAN LAKE
NEWT
1. The Yunnan Lake newt, Cynops wolterstorffi, lived in Kunming Lake in the Chinese province of Yunnan. 2. This newt was 5 - 6 inches long with females being slightly larger than males. 3. The front limbs have four toes. The back legs have 5 toes. 4. The Yunnan Lake newt was black with red-orange spots. The tail of the male would turn blue during mating season. 5. This newt exhibited neoteny, keeping juvenile traits, like gill vestiges of various length, into adulthood. 6. The Yunnan Lake newt lived in the shallow water of Kunming Lake, and would hibernate under the mud of deeper water in winter. 7. Amphibians like frogs, salamanders, and newts are extremely vulnerable to pollution because they absorb water, oxygen, and even toxins through their porous skin. 8. Increased urbanization, rise in pollution, the addition of duck farming and introduction of new fish species proved too much for the Yunnan Lake newt. 9. It was last officially observed in 1979, though a local fisherman claimed to have seen one in 1984.

EXTINCTION DATE
1979
The Yunnan Lake newt was a newt that lived in the region in and around Kunming Lake in the Yunnan Province in China which is 5,905 feet above sea level. In the springtime, thousands of Yunnan Lake newts could be seen swimming among aquatic plants in the shallows during the breeding season. These newts would also move into irrigation canals, ponds, and swamps. During the colder winter months the Yunnan Lake newts would move to deeper water and hibernate under the mud. The newts’ population declined as the urbanization of the area increased. Newts, like all amphibians, are extremely sensitive to changes in the water. The amount of pollution in the water began to take a toll on the newts. The increase in domestic duck farming also affected the water where these newts lived. The addition of non-native fish into Kunming Lake also took a toll on the Yunnan Lake newt population. Many surveys have been done, but the last confirmed sighting was in 1979, although a local fisherman claimed to have seen a newt in 1984. Although Jurassic Park is fiction, scientists are working on several de-extinction projects. In fact, in 2003 scientists did bring back the extinct Pyrenean ibex, a type of wild goat, for 7 minutes before it died, showing de-extinction is possible. The Yunnan Lake newt might be a candidate. Scientists would potentially use DNA from the few remaining skins and specimens at museums. If the Yunnan Lake newt was brought to life, could it ever be reintroduced to its native homeland in Kunming Lake in China? The urbanization in China is in conflict with many native species. Some animals are able to adapt to living alongside humans, and others struggle to survive. The pollution, duck farms, and invasive species brought to the lake would make establishing a wild population difficult at this point. Hopefully in the future it might be possible. If the Yunnan Lake newt was brought back it could be bred in captivity like the Panamanian golden frog, which is currently extinct in the wild but being bred with the hopes it can be reintroduced to its native Panama some day in the future. Perhaps the same could be true for the Yunnan Lake newt.
