The Korean tiger, also known as the Manchurian tiger, Siberian tiger, Siberian tigers, Ussurian tiger, or amur tiger, has a typical lifespan of from 19 years and 9 months to 32 years and 11 months, with a maximum recorded lifespan of 30 years, although its theoretical lifespan is from 13 years and 2 months to 26 years and 4 months; the species reaches sexual maturity between 3 and 5 years of age. The young’s eyes open between 1 and 2 weeks of age, and it begins to walk between 2 weeks and 4 days and 4 weeks. During the embryonic stage, the embryo develops inside the mother, receiving nourishment from her and growing rapidly; the newborn is blind and helpless, and the mother feeds it with milk and protects it in a den during the infant stage. As an adult, the tiger lives and hunts independently, and males defend a large territory, a phase lasting from 2 to 20 years.
