10 animals that live the longest in the earth

Humans are one of the species with relatively high life expectancy and tend to increase with the development of modern medicine. The advances of science and medicine have helped cure many incurable diseases, prolonging human life. However, compared to the 10 most "tough" living animals in the list below, an adult is no different from an infant in the animal world.

10. Rougheye fish

Rougheye is one of the longest-lived fish species, they grow very slowly, it takes decades to become an adult. Rougheye's life span may last for 200 years, with the Rougheye being the longest living record of 205 years. Rougheye often lives at depths of 170 to 700m below sea level, and in Pacific waters.

9. Red sea urchin

Red sea urchin is the largest sea urchin, possibly up to 25cm. They appeared 450 million years ago, and in their lifetimes they are usually very few to move, so the red sea urchins have a lot of spines. Sometimes they often gather together and look for food, but they crawl quite slowly. One thing in particular is the average life span of red sea urchins is 30 years, but if they pass, they can live for more than 200 years.

8. Bowhead whale

Some scientists believe that bowhaed whales may be the oldest mammal species still in the world. A Pacific whale named Bada has lived for about 211 years. Most bowhead whales die between the ages of 20 and 60, but up to four of these whales live between 91 and 172 years old.

7. Koi carp

Although the average lifespan of koi carp is only about 50 years, a special case has helped this small fish named in the list of the "toughest" living animals in the earth. It was a koi named Hanako who lived 226 years, from 1751 to 1977. The life of this fish was confirmed by counting the number of scales on the scales, similar to determining the life of a tree based. into wood grain.

6. Pipe worms Vestimentiferan

This mollusk lives in a protective and fixed shell throughout its life.Vestimentiferan has a body length of up to 3m and often lives in very large groups, which can reach thousands. They live concentrated in the Gulf of northern Mexico, which is more than 750m deep below sea level. Pipe worms Vestimentiferan grow very slowly, usually they can live for more than 250 years.

5. Freshwater mussels

While many animals are difficult to adapt to changing habitats, from climate, geology to many physical, chemical and biological factors change. So freshwater mussels are quite adaptable when they have to completely change their living conditions. Perhaps it is because of this that they can live for more than 250 years. Freshwater mussels are often found in Scandinavia.

4. Turtle

Turtles are still known to have a relatively high life expectancy, on average a healthy turtle can live up to 150 years, but it depends on different turtles. A turtle named Adwaita who lives at a zoo in Kolkata has lived for more than 250 years and died because a crack in the shell became increasingly serious. Without that unfortunate accident, perhaps Adwaita turtle could live a lot longer.

3. Quahog oysters

This oyster is native to the North Atlantic, it lives at a depth of 8 to 396m. To avoid being eaten, they can hide deep in the sea and live there for a long time without looking for food and oxygen.North Atlantic oysters are molluscs with a lifespan of about 400 years, the longest of which can live up to 507 years old. According to the study, the reason they live so long is because the body contains unusually high antioxidant properties.

2. Antarctic sponges

Many people mistakenly think that sponges are plants, but in fact they are a less active animal, every day they move only 1mm. Sponges also have a very slow growth rate, so they have a long life cycle. Conventional sponges have a lifespan of three to twenty years, only Antarctic sponges have a lifespan of up to 1550 years.

1. Immortal jellyfish

The jellyfish has the scientific name of Turritopsis nutricula , which has a special ability to reverse its life cycle from adulthood back to the single-celled period and from there to continue to grow. This is the only case ever discovered about a multicellular organism capable of reversing the life cycle when mating after sexual maturity. Theoretically, this process is infinite, and leads to this kind of immortal jellyfish.
