Longest living animals

The life of humans on the planet can be considered short if we compare it with the lifespans that some animals have. While humans have an average life expectancy of 72 years according to the World Health Organization (WHO), there are some creatures on the planet who are immortal and some can live up to thousands of years. Scientists are trying to find out why some animals live so long, trying to unravel their mysteries and hope to be able to use this knowledge to extend the human lifespan. Here is a list of some of the longest living animals:

1. Turritopsis dohrnii

The jellyfish Turritopsis dohrnii has no brain and heart and is considered the only immortal creature on Earth; it lives in tropical waters. As scientists have proved, such jellyfish do not die of old age, living up to a certain age, they begin to get younger and return to their original stage. And from the stage of a young individual, she again begins to develop. Fortunately, there is no limit to the number of times they can do this! Thus, a creature can live an infinite number of cycles. Such jellyfish die, most often, due to predators or diseases. Sponges have this incredible longevity thanks to their slow growth and generally cold water environment.

2. Antarctic sponge

The Antarctic sponge holds the record for the longevity of its kind. The creature lives in arctic cold waters. Every year the sponge grows by 0.2 mm, while it lives at a depth of about 200 m, where sunlight practically does not penetrate. By reducing the metabolic process, the Antarctic sponge can live upto 5,000 to 15,000 years.

3. Red Sea Urchin

Next on the list is Red Sea Urchin, a sea creature, which is native to the Pacific Ocean, mostly found along the west coast of North America. These creatures live in shallow areas, mostly near rocky ones where low tides reach 90m. They can also be seen crawling along the ocean floor with the help of their spines. In addition to its size and spines, the giant red sea urchin stands out as one of the longest-living animals, as it can reach up to 200 years.

4. Koi Fish

The Japanese gave the name Hanako to one well-known centenarian. At first, koi carps were eaten, later they began to be kept at home as ornamental fish.

It is said that this male tortoise weighing upto 250 kg of Algebra species was gifted to Lord Clive, the founder of the British Empire in India. The average lifespan of these tortoises is upto 150-250 years.

The credit for being the longest-living mammal on the planet goes to the bowhead whale, also known as the Arctic whale. Many of them are believed to be over 200 years old, while the oldest known of them is 211 years old. Bowhead whales have a gene in their body, which is called ERCC1 that keeps on repairing the damaged DNA in the body. Therefore, these fish do not have terrible diseases like cancer, neurodegenerative, cardiovascular and metabolic. They grow upto 60 feet (18.3 m) and 200,000 pounds (91 tons) and eat around 220,000 pounds (100 tons) of food a year.

8. Greenland Shark

The Greenland shark lives deep in the Arctic Ocean belonging to the somnios family. The sharks grow about 0.5 to 1 cm a year and can grow up to 24 feet long and can live in water and the only shark that can tolerate Arctic temperatures year round with a temperature of 7 to -2 degrees. This is very strange since most sharks are thermophilic. The animal lives upto 100-200 years, which is the greatest indicator for sharks. The creature is not picky about food, it eats any living creatures. The maximum age of the Greenland shark that could be determined is 392 years. The studies were carried out using radiocarbon testing of the lens of the eye. The Greenland shark is probably the longest-lived vertebrate animal.

9. Rougheye rockfish
