How long do crocodiles and alligators live?: Information Roundup
The longevity of crocodiles and alligators can be only conjectured. Evidence is not available to prove or disprove the common notion that they attain greater ages than many other creatures. It has been generally assumed that crocodiles live to be very old because they grow slowly, but it is now known that crocodilians grow more rapidly than was formerly supposed. Some of the sacred crocodiles of India are believed to be more than a century old. Alligators in captivity have been known five forty or fifty years without showing any signs of senescence.
