The Yangtze sturgeon lived in its namesake river for 140 million years. Now it doesn’t. Nor does another behemoth it shared China’s longest waterway with for ages, the Chinese paddlefish. Updating its Red List of Threatened Species on Thursday for the first time in 13 years, the International Union for Conservation of Nature declared the two species, known as “the last giants of the Yangtze,” extinct. |

Once the largest freshwater fish in the world, the Yangtze sturgeon, Acipenser dabryanus, could reach 26 feet in length and weigh 1,500 pounds. Its historic range extended throughout Asia, including Japan, Korea, and the Yellow River in China. Dubbed a “living fossil,” it sported a rounded snout, large pectoral fins, and rows of elevated ridges on its spine and flanks. Though there are still captive fish in breeding programs, authorities, despite many efforts, have failed to successfully reintroduce the fish to the river system, and now it considered extinct in the wild. |
