The 10 Oldest Living Things On Earth

Updated October 14, 2019 683.8k views10 items

This list of the oldest living things on Earth, including the oldest animals, species, and organisms, will definitely make you feel young. You could probably nitpick some of these life forms within a million years here, a million years there... but the fact remains that these animals have been around a loooong time. What are the oldest living organisms on earth? And more importantly how have they stuck around this long?

These ancient organisms have been around for millions, or ever billions of years and have achieved apparent perfection in their environment. Millennia have passed, and they keep on keeping on. Sure, a tail might shorten, an extra tentacle might grow, or they might develop a more streamlined coat of armor... but, like that guy you know with the haircut he's had since high school, these animals have asked themselves the question: Why change it if it's working?

These are the oldest living things on the planet, and they just might still be here long after we are nothing more than fossils found buried in a pile of styrofoam take-out boxes.
