AnAge entry for Crocodylus johnstoni

Classification (HAGRID: 02886)

Taxonomy: Kingdom: Animalia
    Phylum: Chordata
        Class: Reptilia (Taxon entry)
            Order: Crocodilia
                Family: Crocodylidae
                    Genus: Crocodylus
Species: Crocodylus johnstoni
Common name: Johnson's crocodile

Maximum longevity: 55 years (wild)
Source: ref. 1298
Sample size: Medium
Data quality: Questionable
Observations: Age estimates using skeletochronology suggest that these animals can live over 50 years [1082], which is plausible. A female at least 55 years old was reported in captivity [1298]. In conditions of scarce food, growth and sexual maturity are delayed in these animals [0586]. One study found that mortality slightly increases with age [1150].
