Koi usually live 25-30 years, but there are reports of koi over 200 years old! A famous koi in Japan named ‘Hanako’ died in 1977 and a study of the growth rings of one of her scales revealed she was 226 years old! This made her older than the United States of America!

Native to New Zealand and Australia, these eels often live up to 60 years old with the oldest living New Zealand eel recorded as being 106 years old! Like the Greenland shark, these fish grow very slowly, which is why they can live to be so old.

Macaws can live up to 60-80 years while their reproductive age ranges from 30 to 35 years. Unfortunately, the majority of macaws are now endangered in the wild and some have already become extinct due to habitat degradation and the illegal pet trade.

The largest living turtle species that can survive well well past one hundred, the oldest of which is at 152 years old. The most famous Galapagos giant tortoise ‘Lonesome George’, a subspecies that lived on the islands, it was 100 years old and still classified as a young adult! He had become something of an ambassador for the islands off Ecuador’s coast whose unique flora and fauna helped inspire Charles Darwin’s theories of evolution.

These sharks can live up to 200 years, although one individual was found to be 400 years old – making it the oldest vertebrate in the world. They live so long because they grow very slowly. They grow about 1cm a year and mature at about 100 years old, well that’s a long childhood!

2. North Shrink

A very unique jellyfish that can revert to its premature state of health when exposed to stress or injury. While this means it’s biologically immortal, in practice they don’t live forever and like other animals, they get injured and eaten.
