Longest living animal is...
 

While we know plants ( like trees, moss like plants) are the longest living plants ( and maybe some alien humanoid species out there ) the known world's oldest creature is revealed to be 507-year-old shellfish called Ming – until scientists KILLED it by opening it up to check its age.

Kinda interesting read.

Wonder how long our maxima clams live.

So curiosity killed the clam

Well he should have told them when they asked. But OH NO he had to clam up!!

Must have made some very tough chowder...
