The Siberian musk deer has a typical lifespan of from 7 to 18 years, although its theoretical lifespan can extend from 15 years and 3 months to 19 years and 8 months. The species reaches sexual maturity from 1 to 1 year and 8 months of age. The embryo develops inside the mother, receiving nourishment through the placenta and not eating independently. A newborn musk deer, which is a young animal, has its eyes open and begins walking immediately after birth; it is covered in fur with white spots, quickly stands on its legs, and feeds on its mother’s milk for a period of from 1 day to 6 months. Following this stage, the animal enters the adult phase, which lasts from 1 year and 6 months to 18 years, during which it is capable of reproduction and lives independently in the forest.
