Try this. Though this might be Outdated Research Material. But there is an animal Scientist have been studying Called the Immortal Jellyfish that might just Have the key to Immortality in General. Or longer life span.

And then there's this I saw while looking around. Hydras. They do not Age at all or die. So this one might help alot in the search for immortality in General.
