Life span of Nile Crocs

this was suprisingly difficult to find on the web. what is the age for wild ones and captives? i have heard 100-150 yrs, but also have heard 80, for captives.

100 years:

No, wait…20 years!

Er…70 to 100 years, maybe?

Most other sites seem to confirm the 70-100 years range, with [this document](www.rotterdamzoo.nl/uk/r_zoovenirs/ werkstukken/blijdorp_krokodil.doc) (it’s an MS word doc) stating

Also, according to this site:

I just watched a documentary on Animal Planet last night about Nile crocs. It mentioned that the life span of an adult male was usually 80 years, although some may live to be 100. Of course, the vast majority of Nile crocs do not make it to adulthood, becoming meals for other animals, including cannibalistic Nile crocs. :eek:
