On this day 37 years ago, on September 19, 1988 (August 9, 1988 in the lunar calendar), the Soviet Union revived an amphibian that had been frozen for 90 years. On September 19, 1988, Soviet gold detectors found an amphibian frozen for 90 years in the permafrost of Siberia and successfully revived it. The news said that the amphibian with a tail belonged to the small salamander family and was found in the isolated Kolyma region of Siberia. When it was frozen in an 11-meter-long tree trunk under the permafrost, it was brought back and placed in a water basin. The animal slowly revived. Scientists say that the animal can survive in such cold conditions for a long time because its liver is different from other animals. Its liver is about one-third of its body weight and can secrete glycerin, which acts like a "special antifreeze."
