Alpacas typically live for 15 to 20 years, with a maximum and theoretical lifespan of 25 years and 10 months. The species reaches sexual maturity between 1 year and 5 months and 3 years of age. At birth, the young alpaca’s eyes are open and it begins to walk. The embryo develops inside the mother, receiving nourishment through the placenta and not eating independently. The infant alpaca drinks its mother's milk and learns to eat grass during a period lasting from 1 day to 8 months. An adult alpaca is capable of reproduction and independent living, with this stage lasting from 1 to 20 years.
