What is the longest life span of an animal on Earth?

Answer 1

The giant tortoise lives very long, about 177 years in captivity.

However, the bowhead whale, the second largest whale behind the blue whale, can live to over 200 years due to its low metabolism and size.

Answer 2

The longest average life span is about 80 years for a turtle. However, a turtle can live up to 177 years (the record). There was a koi fish which apparently lived up to 226 years old! Also, Icelandic Cyprine Arctica islandica (also known as an ocean quahog) is a mollusk that is estimated to have lived for 405-410 years!

A giant tortoise. It lives for roughly 200-300 years!

Edit:(ryon) This is a highly debated subject, in fact in general definition an animal is any living organism that has voluntary motion, and with claims of bacteria, and other micro organism, that can still be classified as animal, and some labs having results from reviving some of those micro organism possibly dating back many millions of years, also some sea organism such as the sponge is considered an animal and some date over 1500 years old.
A creature with longest lifespan ever recorded is Quahog. A specimen of the Icelandic Cyprine Arctica islandica (also known as an ocean quahog), a mollusk, was found to have lived 405 years and possibly up to 410. Another specimen had a recorded lifespan of 374 years.
