For how many years does a crocodile live?

All species of crocodile have a lifespan of 30–40 years, with the larger species having a lifespan of 60–70 years. As with most animals, longevity is greater in captivity, where they get regular food, medical treatment and habitat without competing threats (typically, other male crocodiles). read more

The species known to live the longest in the wild, though, is the saltwater crocodile, the largest-living reptile. Saltwater crocodiles usually live for 70 years, while some have been found to live for 100. read more

C. porosus is estimated to live around 70 years on average, and there is limited evidence that some individuals may exceed 100 years. Certainly, individuals in many aboriginal tribes recognise very old crocodiles that have been alive for as long as they can remember. The same is true of C. niloticus, which probably lives nearly as long as the saltwater crocodile. One of the oldest crocodiles recorded died in a zoo in Russia apparently aged 115 years old. read more
