Scientists reveal two “immortals” among the 10 longest-living creatures on the “Incredible” list

admin

A scientific journal published a list of more than 10 life-spanning animals on the planet, but what is interesting in this list is the presence of two animals that were considered “immortal animals” due to the inability, so far, to accurately determine their very long lifespans.

The animal kingdom is proud of the lifespan of some of its very long creatures, which exceed the lifespan of humans by stages, as humans may have an “absolute limit” of age that may reach 150 years, but this number is a small stage in the life of these animals, whose ages are estimated by centuries and some by thousands of years, According to the sources.
And the scientific “livescience” magazine published a list of the lifespans of the 10 longest animals on earth, from the least to the longest, and although everyone expected the turtle (the oldest turtle at 150 years old) within this list, despite its long life, it is outside this exciting table. Two creatures in the “immortal animals” category were placed at the bottom of the list.

Bowhead whale… 200 years old

The bowhead whale (Balaena mysticetus) is the longest-living mammal, which is also known as the Greenland right whale and the ermine whale. It is a marine mammal belonging to cetaceans, living in the Arctic Ocean, where its lifespan reaches about 200 years due to the presence of a genetic mutation called (ERCC1). ) Able to repair damaged DNA.

rugby rock fish… 205 years

The rock rugby fish (Sebastes aleutianus) is one of the longest-living fish with a maximum lifespan of at least 205 years.

These pink or brown fish live in the Pacific Ocean from California to Japan. They reach 38 inches (97 cm) in length and feed on other animals such as shrimp and small fish, and are critically endangered.
Freshwater pearl dates… 280 years old

Freshwater pearl mussels (Margaritifera margaritifera) open their shells to filter food particles from the water. It lives mainly in rivers and streams and can be found in Europe and North America.

Studies show that the oldest freshwater mussels are 280 years old, according to the World Wildlife Fund (WWF). These invertebrates have a long life span thanks to their low metabolism.
Greenland shark… 272 years old

The Greenland shark (Somniosus microcephalus) lives in the depths of the Arctic Ocean and the North Atlantic Ocean.

They can reach 24 feet (7.3 m) in length and have a diet that includes a variety of marine animals, including fish and marine mammals such as seals.

A 2016 study of Greenland shark eye tissue, published in the journal Science, estimated that these sharks could have a maximum lifespan of at least 272 years. The study estimated that the largest shark ever spotted was around 392 years old, and researchers suggested that these sharks may have been 512 years old.

Tube worms… 300 years old

Tube worms are invertebrates that enjoy a long life and live in the cold environment and take their place in the deep sea. A 2017 study published in The Science of Nature found that these worms regularly live for up to 200 years, and some specimens have lived for more than 300 years. These worms have a low mortality rate due to the scarcity of predators in their environment.

Oceanic clam… 507 years

The oceanic clam (Arctica islandica) lives in the brackish waters of the North Atlantic Ocean much longer than the other bivalve species on this list.

One of them was found in 2006 off the coast of Iceland. It was estimated to be around 507 years old, according to the British National Museum of Wales. The ancient clam was called “Ming” because it was born in 1499 when the Ming Dynasty ruled China (1368-1644).

Coral reefs… 4 thousand years old

Coral reefs look similar to the colorful boulders and vegetation within the ocean, but are actually made up of invertebrate exoskeletons called polyps.

These invertebrates constantly reproduce similar to polyps and replace themselves by creating a genetically identical copy of themselves, which over time causes the corals’ exoskeleton to grow larger and larger. Coral life is therefore a “collective effort of a single parent group”.

Corals can live for hundreds of years or more, but deep-water black corals (Leiopathes sp) are among the world’s longest-lived corals, with samples of black coral found off the coast of Hawaii estimated to be 4,265 years old.
Glass sponge colonies… 11,000 years ago

Sponges are similar in composition to coral reefs, as they live in groups in the form of colonies, and their life cycle reaches thousands of years.

The glass sponges are among the longest-lived sponges on Earth, and they spread in the depths of the ocean, and they have bony, glass-like shapes.

A 2012 study published in the journal “Chemical Geology” estimated that the glass sponge belonging to the species “Monorhaphis chuni” was about 11,000 years old. Other sponges may be able to live longer.

Immortal jellyfish…information from the world of imagination

Scientists call the jellyfish “Turritopsis dohrnii” the “immortal jellyfish” because it has the potential to live forever, according to the source.

This jellyfish begins its life in the form of larvae, before spreading its parts on the sea floor in the form of chains, which spread similarly to benign crabs, as these small tumors on their edges turn into new jellyfish.

The origin of this jellyfish dates back to the Mediterranean Sea, and this life cycle is repeated several times, and therefore these creatures never die under the right conditions, according to some scientists.

Small jellyfish are less than 0.2 inches (4.5 mm) in size, many of which are devoured by other animals such as fish and others, thus preventing them from achieving actual immortality.
Hydra… the “immortal” enteropods

Hydra is a group of small invertebrates with soft bodies somewhat similar to a jellyfish. The hydra or “hydra” is one of the most common aquifers and is abundant in fresh pond waters. The hydra represents a simple model of the cylindrical adenoid structure.

According to “Live Science”, this creature does not show signs of ageing. These invertebrates are largely made up of stem cells, which are constantly renewed through the process of duplication or cloning.

Hydra does not live forever under natural conditions, suffering from the presence of various threats such as predators and diseases, but without these external threats, it can be “immortal” according to the source.
