In this Article We’re Going to Review to you the longest livingin the World – You may not Know Some of those
Animals living in natural conditions rarely approach their maximum possible age because of very high mortality rates due to infant mortality, disease, predators, bad weather, habitat destruction or competition for food and territory.
Below are ten animals that would have the longest lifespan under ideal conditions.
1. Koi carp
Koi usually live between 25 and 30 years, but there are reports of Koi that have reached the age of over 200 years. A famous koi in Japan, named “Hanako”, died in 1977 and a study of the growth rings of one of its scales revealed that it was 226 years old, which means it was older than the United States of America!
2. Long-finned eel
Native to New Zealand and Australia, these eels often live up to 60 years, with the oldest living long-finned eel being 106 years old. Like the Greenland shark, these fish grow very slowly, which is why they can age so long.
3. Red sea urchin
Red sea urchins are believed to be almost immortal. They are found in the shallow waters of the Pacific Ocean along the west coast of North America. These small, spiny creatures can live for over 200 years.
Macaws can live up to 60 or 80 years, while their reproductive age ranges from 30 to 35 years. Unfortunately, the majority of macaws are now threatened in the wild and a few are already extinct due to habitat degradation and the illegal pet trade.
5. African Elephant
The largest surviving land animals have an average life expectancy of 70 years and a recent Zimbabwean study showed that female African elephants can potentially remain fertile until death.
6. Galapagos giant tortoise
The largest living species of turtle that can survive well over a hundred years, the oldest is 152 years old. The most famous Galapagos tortoise was called “George the Solitary”, a subspecies that lived on the islands. It was 100 years old and was still considered a young adult. It had become something of an ambassador for the islands off the coast of Ecuador, whose unique flora and fauna inspired Charles Darwin’s theories of evolution.
7. Bowhead whale
The bowhead whale has an average life expectancy of 200 years and is the second largest mammal after the blue whale. It was the discovery of a live animal with a harpoon from over 100 years ago in its skin that provided information on their longevity.
8. Immortal Medusa
A unique jellyfish that can return to its premature state when exposed to stress or injury. Although this means that they are biologically immortal, in practice they do not live forever, are injured and eaten like other animals.
9. Greenland shark
These sharks can reach the age of 200 years, although a 400-year-old individual has been found, making it the oldest vertebrate in the world. They live so long because they grow very slowly. They grow about 1 cm per year and reach maturity around the age of 100 years, that’s a long childhood!
10. Icelandic prairie
The age of some specimens collected has been estimated at over 400 years. These animals show exceptional longevity, the highest reported age for the “Ming” clam being 507 years. This clam was so named because it is believed to have lived during the Chinese Ming Dynasty.
