Longest living animal # 5 – Lamellibrachia Tube Worm

Longest living animal # 4 – Greenland Shark

Sharks are one of the longest living animals on the planet, and the Greenland Shark species takes the cake when it comes to lifespan.

On average the live for about 200 years, but one was found to have lived for about 400 years. Due to its long lifespan, it is the longest-living vertebrae known to man.

Longest living animal # 3 – Ocean Quahog Clam

Ocean Quahog (not to be confused with the Family Guy character!) is a species of clam with incredibly long lifespans, and is easily one of the longest living animals on Earth.

Based on some collected specimens, the lifespan of the Ocean Quahog clams have been estimated to be around 400 years long.

There was even one – the famous clam, Ming – who is reported to have lived for a whopping 507 years! It was killed accidentally while scientists were trying to retrieve it. The irony… 

Longest living animal # 2 – Antarctic Sponge

How long can they live: 15,000 years!

Yes, you read that right. 15,000 years. Antarctic Sponges live in extremely cold temperatures which is the main reason why they live for such an incredibly long time.

Studies have found that the sponges that live deeper tend to live longer, which would make sense since the deeper they live, the colder it is.

Longest living animal # 1 – Turritopsis Dohrnii Jellyfish

How long do they live: Forever (unless they are eaten of course!) 

The Turritopsis dohrnii species of jellyfish is basically immortal, thanks to its ability to between adult stage and infant stage. That makes them the absolute longest living of the longest living animals on Earth!

In theory, it can do this in perpetuity, so unless there are external harmful factors (like predators or accidents) to deal with, they can continue to live forever!

Closing thoughts

The thing about long life is that it is always subject to the circumstances the animal experiences. In good circumstances and ideal scenarios, they will live long. On the other hand, if their circumstances are challenging, then even the longest living animal won’t survive for long (think dinosaurs…).

But hey, that’s just how life works.
