AnAge entry for Hippopotamus amphibius

Classification (HAGRID: 01702)

Taxonomy: Kingdom: Animalia
    Phylum: Chordata
        Class: Mammalia (Taxon entry)
            Order: Artiodactyla
                Family: Hippopotamidae
                    Genus: Hippopotamus
Species: Hippopotamus amphibius
Common name: Hippopotamus

IMR: 0.01/year
MRDT: 7 years
Maximum longevity: 61.2 years (captivity)
Source: ref. 671
Sample size: Large
Data quality: Acceptable
Observations: Tooth erosion is a common age-related change in these animals. In captivity sexual maturity is attained at 3-4 years but in the wild mating does not occur until males are 6-13 years and females are 7-15 years [0434].
