It depends on your definition of animal and life. Members of the turtle and tortoise (both giant and normal) can live to 150+ as the previous answer said however they have found bacteria in places like Antartica that are thousands of years old but, of course, have spent that life in a sort of suspended animation. So as you see it depends on the definitions.
The ocean quahog - 220 years. Also blue whales are now known to live longer than previously thought - some have been found with 18th-century whaling spear-heads embedded in their skin, showing that they can live to 200 or more.
btw, I don't know what a "quahog" is, that's just what the Guinness Book of Records says.
