Human life on earth can be considered short if we compare it with the life span of other animals. While humans have an average life expectancy of 72 years, according to the World Health Organization (WHO), there are several living things on the planet that do not die and some may live for thousands of years.
Scientists are trying to find out why other animals live longer, trying to unravel their mysteries and hoping to use this knowledge to prolong human life. Here are some of the longest-lived animals:
The Jellyfish by the name Turritopsis dohrnii has no brain and heart and is thought to be the only immortal creature on earth; it lives in tropical waters.
As scientists have proved, jellyfish do not die of old age as they live to a certain age and then begin to grow younger and return to their natural state.
And from that point on, it begins to grow again. Fortunately, there is no limit to the number of times they can do it! Thus, this creature can survive indefinitely.
2. Greenland shark
The Greenland shark lives in the lowest depths of the Arctic Ocean and comes from a family known scientifically as somnios.
This shark grows up to 0.5 to 1 centimeter per year and can grow up to 24 feet tall and can live in the water and is the only shark that can withstand the Arctic temperature all year round with a temperature of 7 to -2 degrees.
This is very surprising as most sharks are intolerant in temperatures above 40c. This animal lives up to 100-200 years, which is a major indicator for sharks.
This creature does not choose food, it even eats living things. The maximum age of the Greenland shark can be confirmed is 392 years.
3. Bowhead Whale
The longest-lived mammal on the planet goes to the whale by the name Bowhead, also known as the Arctic whale. Most of them are believed to be over 200 years old, while the oldest known is 211 years old.
These whales have a gene in their body, called ERCC1 which continues to repair damaged DNA in the body. Therefore, these fish do not have serious diseases such as cancer, cardiovascular disease.
4. Koi Fish
Koi is a small kept fish for decoration. The oldest koi fish died at the age of 226 in Japan in 1977, on average, they live for 40-50 years.
The country of this subspecies of these fish is usually China, but this fish gained more popularity in Japan, where it has grown significantly.
The Japanese named Hanako after one of the most famous people. At first, koi fish were eaten, and later they began to be kept at home as ornamental fish.
5. Large Galapagos tortoises
The giant Galapagos tortoise is known for the famous Galapagos archipelago and has been considered one of the world's largest living organisms and, therefore, as the world's largest living invertebrate, about 200 years old.
In 2006, a male tortoise named Adwaita died at the age of 255 at the Alipore Zoological Gardens in Kolkata. He subsisted on fodder of wheat bran, carrots, salads, dipped grams (chickpea), bread, hay and salt.
It is said that this male tortoise weighing up to 250 kilograms of Algebra species was presented with a gift by Lord Clive, the founder of the British Empire in India. The average life span of these tortoises is over 150-250 years.
6. Rougheye Fish
Rougheye rockfish is one of the largest living fish. They live for about 205 years. These fish are found in the Pacific Ocean from California to Japan.
They can grow up to 38 inches in height. However, the risk of extinction has also increased with this species, leading to many campaigns to sensitize people about the importance of conserving this species.
