Most of the Scientists claimed that the fundamental unit of life is the cell for any living organism to live as long as possible, it works properly to maintain a healthy stasis for the cells that comprise it. From longevity, antiquity, and the immortality of living species and it has been a subject of research and study for many great scientists, thinkers, and philosophers.
The main reason why scientists team believe that the undercover to longevity and possibly to immortality is hidden in nature, to be more appointed, in other living organisms that appear to live unrealistically long.
Really, these organisms are much older than your grandma, here is a list of 20 longest living animals who are really longer than your grandma.
Here Are the 20 List Of Longest Living Animals
1. Bowhead Whales
Bowhead Whales are the longest living animals, can live as long as 200 years. evidence of modern scientific research has published that it could possibly be the longest-living mammal on the planet.
However, the bad news about bowhead whale is that in most cases the scientists have calculated their age through a necroscopy, which was the case of a bowhead that was killed by Iñupiat Eskimos in northern Alaska and was estimated to be 211 years old.
Even then researchers said that a bowhead whale could live more than 250 years if Iñupiat hunters did not disturb him.
2. Freshwater Pearl Mussel
Freshwater Pearl Mussel is considered as the longest living animal of freshwater mussel also known by its scientific name Margaritifera Margaritifera. A research team of Finnish malacologists later affirmed his finding and uncovered that the most established recorded creature in Finland’s history is a Margaritifera that was assessed to be between 210 and 250 years old.
For that reason, marine scientists and malacologists alike have given much consideration to the species in ongoing decades, with Russian malacologist Valeriy Zyuganov increasing worldwide consideration upon his disclosure that a freshwater pearl mussel could live up to 250 years.
It has recently been sorted by the International Union for Conservation of Nature as likely to become extinct.
3. Honey Fungus
Honey fungus is known as Armillaria and a genus of parasitical fungi that commonly live on trees and woody shrubs. In the year of 2000, a research team of mycologists discovered an individual fungus, Armillaria Ostoyae, in Malheur National woodland in eastern Oregon which portrayed the scientific community for its size and long life span. It was calculated to be 2400 years old and covered 3.4 square miles.
A Frenchwoman named Jeanne Calment who died at age 122 and 164 days. If you seek online where you will get many unproven reports of people who managed to live hundreds of years, Methuselah being a principal example, the longest historically recorded human life. Obviously, we can not go without talking about our own species on this list, now can we?
Moreover, the talent of humans and animals, although they tend to grow old pretty fast, particularly compared to creatures such as plants, aquatic animals, and various other microorganisms, appear to be one of the longest-living terrestrial animals.
According to the research of scientists disclose in the journal Experimental Gerontology, biologists are particularly fascinated by hydrae due to their amazing regenerative ability, while some scientists say that hydra can be cover up the secret of immortality for humans.
However, hydra that reproduces sexually will eventually age and die just like humans or other animals. It is believed to be one of the very few organisms that are biologically immortal and there’s no senescence in their kind. What does that mean? Just put, their cells divide forever and as a result of a hydra never grows old.
6. Koi Fish
Koi fishes are considered as the second-most-famous fish used for decoration, behind goldfish. It usually kept for decorative purposes in outdoor koi ponds or water gardens. Also known for their unusual lifetime and for their fascinating variation in color.
They can come in white, red, yellow, blue, black, cream, and other color combinations as well. They can live for 200 years or more. The most famous example from the owner of koi fish called it Hanako, who died at the age of 226 years on July 7, 1977.
Leiopathes are one of the oldest organisms in the sea. They have every other black coral that belongs to the order of Antipatharica. However, a marine scientist team suggested that Leiopathes corals might be some of the longest-living species on the planet. They also found that the life span of Leiopathe in excess of 4,500 years, which of course makes it one of the oldest-known marine organisms in the world.
Wonderfully, they are named as Leiopathes to see their dark skeleton. Sad to say, we don’t know much about Leiopathes corals and their biological status because they live in deep, cold, dark waters that human beings haven’t managed to fully explore yet.
Truth be told, their quality appears to increment as they age much of the time, with the prime example being George the Lobster, a monster American lobster that was caught in 2008 and awed everybody with his weight (20 lbs) and incredible strength. As per sea life researchers, he was born around 1869, which would presently make him 145 years of age.
In opposition to different urban legends and images you may have found out about lobsters, truly this delightful armor-clad is as mortal as people and regardless of whether left undisturbed by man and other ocean predators, it will one day die from old age.
However, scientific studies have demonstrated that lobsters don’t age like most other living creatures, their conceptive capacities don’t diminish, and their metabolism doesn’t slow down as they grow older.
9. Macaw Parrots
It is one of the most famous occurrences of a Blue-and-yellow Macaw living quite long is that of a female named Charlie who was hatched in 1899 (according to estimates), which would make her about 115 years old. She came back particularly in 2004 when BBC News claimed Longest Living Animal Charlie had formerly belonged to Winston in the 1930s.
This information marks that Churchill’s daughter didn’t verify, perhaps she wasn’t sure about the story’s validity herself. Macaw Parrots is a member of a big group of Neotropical parrots that are known for two things like amazing capability to age slowly and live a long life; and real outlook, exotic color.
10. Old Tjikko
In 2008, Old Tjikko which is five-meter tall Norway spruce was discovered by geologist and professor Lief Kullman of Umea University and is located in Sweden. Leif Kullman named this tree after his dead dog.
At almost 9,550 years old Tijikko is also considered to be one of the oldest single-stemmed clonal trees and took root not long after the glaciers received from Scandinavia after the last ice age.
11. Orca Whales
Orca Whales are considered as the longest-living mammals on earth and also known for having one of the slowest heart rates as well. We just knew but didn’t collect the exact numbers but this is not the case anymore. A scientist said an orca who was born around 1911 and so is believed to be about 103 years old at the moment, a real fact that gives the record for being the oldest-known orca alive.
A recent report of the average life span of a female orca around 70 to 80 years, but Granny’s case has made many marine scientists question the accuracy of their theories or whether Granny is just a sole exception to the system.
12. Silene Stenophylla
The Russian team of scientists discovered and tested a seed cache of Silene Stenophylla, and ensured through radiocarbon dating that the seeds were an incredible 32,000 years old. Really, It makes Silene Stenophylla the oldest plant ever to be regenerated in history. This flowering plant native to Siberia, which had been buried by an ice age squirrel near the banks of the Kolyma River.
Sponges are known for their truly fantastic diversity since they arrive in an immense verity of colors and shapes. They are one kind of Longest Living animals and don’t have internal organs or muscles and even more amazingly, they lack a nervous and circulation system.
They also have lined walls with many small pores called Ostia, that allow water to flow into the sponges. The most impressive thing about the sponge, like a marine scientist has found a 10,000 years old sponge in Antarctica.
Sturgeons are considered as very tasty meat and known as one of the best “catches’’ for any fisherman in the United States. The national resources department tagged one 125 years old female sturgeon in Wisconsin.
It can grow about 7’3 inches-long that found biologist Ron Bruch after a closer examination. Sturgeon of 240-pound was born around 1887, which means the anthropophagous sturgeon is currently 127 years old and still alive.
15. The Immortal Jellyfish
The Immortal Jellyfish or Turritopsis Nutricula is the only living organism found in the Mediterranean sea and in the water of Japan. Scientists say jellyfish is able to revert back to a juvenile form once it mates after becoming sexually mature, and it can potentially live forever in this way. The Turritopsis Nutricula is classified as a very small predatory animal.
It is also known that this creature is capable of reverting completely to its younger self and scientists believe that the cycle can repeat indefinitely, which means that the “immortal jellyfish” might really be immortal after all.
16. The Ocean Quahog
The Ocean quahog is known as the long-lived animal and really big for its kind since as well as it can grow up to 13-14cm across. This animal usually lives buried in both dry and muddy sand, and up to a depth of 500 meters, often with its shell entirely hidden and simply a small tube rising to the surface of the seabed.
In addition to that, It also is known as Arctica Islandica, which is a classic marine Bivalve mollusk, and the two halves of its confide in, the rounded shell is thick, glossy and dark brown in color. Researchers found two Ocean quahog they have lived respectively 507 years and 375 years.
According to the researcher of scientists, a zoo employee who took care of Adwaita, plenty of animals weighed about 590 lbs and some of these favorite foods added carrots, bread, lettuce, and grass. Male Adwaita was born in Seychelles around 1750 was about 255 years old when he died in 2006.
He lived in the Alipore Zoological gardens of Kolkata, India. Adwaita was alive through four different centuries during the course of his life, in fact, it proves as the longest-living animals in history.
Tuatara is an unusual, little-sized animal that can be found only in New Zealand. It is considered as the Longest Living animal in history. An adult tuatara ranges from about 300 grams to 1 kg, they are also considered to be the only surviving members of the Sphenodontia family, which was illustrated almost 200 million years before by many species during the age of the dinosaurs.
However, about about 60 million years ago, all these species vanished and became extinct except the tuatara, a fact that makes them an endangered species, and one of the most ancient animals in the world.
In the year of 2002, “tuatara” named Henry by his owner and underwent surgery to remove a tumor from his genitals and in 2009 at the age of 111 he mated for the first time with Mildred an eighty-year-old female and had 11 baby tuatara.
19. Tube Worms
According to scientific research, it is trusted that average 2-meter-long Tube worms can live from 170 to 250 years. In the year of 2000, a Penn State research team found that the Tube worms that live in the cold and calm hydrocarbon-seep sites in the Gulf of Mexico have surprisingly way longer life spans compared to their distant cousins living in the hot and dynamic hydrothermal vents, reported a newspaper.
20. Sea Urchins
Most of the scientists researched sea urchins seem to have high mortality rates and their deaths are a result of being preyed upon by man and other sea creatures. A real example is known as Mesocentrotus Franciscans can live up to 200 years if it doesn’t become food for fish or humans in the meantime.
It seems to prefer the waters of the Pacific since and can be found in great quantity anywhere from Alaska to Baja California. Generally, they live in shallow waters and located on rocky shores protected from acute wave action.
