- Crocodylus johnstoni
- Common name
- Johnson's crocodile
Lifespan, ageing, and relevant traits
- Maximum longevity
- 55 years (wild)
- ref. 1298
- Sample size
- Data quality
Age estimates using skeletochronology suggest that these animals can live over 50 years , which is plausible. A female at least 55 years old was reported in captivity . In conditions of scarce food, growth and sexual maturity are delayed in these animals . One study found that mortality slightly increases with age .
