- Observations
Males are sexually mature at one year of age but do not normally reproduce until they are two years of age. Females generally stay with parents for two years. In the wild, these animals are capable of reproducing up to 7 years of age [0646]. One captive specimen lived 12.6 years [0671]. The high parental care and long time to maturity partly explain the longer lifespan than that of similar species.
