Humans are one of the species that have a fairly long life expectancy and tend to increase with the development of modern medicine. Advances in science and medicine have helped cure many incurable diseases and prolong human life. However, if compared with the 15 most "tough" living animals in the list below, an adult is no different from a newborn baby in the animal world.
16. New Zealand longfin eel
New Zealand longfin eels are native to New Zealand and Australia, these eels usually live to be 60 years old and the longest recorded individual is 106 years old.
Like blue sharks, these fish grow very slowly, which is why they are able to live so long.
15. Tubeworm Lamellibrachia
These colorful sea creatures live along hydrocarbon vents on the seafloor. They live about 170 years, but many scientists believe that some individuals live up to 250 years. Lamellibrachia grows slowly throughout its life with a length of more than 182cm. This creature is found in the Atlantic Ocean, especially the shallow areas of the Gulf of Mexico basin.
14. Tuataras . Lizard
The two species of Tuataras alive today are the only surviving members of the group of animals that flourished 200 million years ago, living dinosaurs. They are also one of the longest living vertebrates, ranging from 100 to 200 years.
13. Proboscis snails
The heliotrope snail, native to the Pacific Northwest, is an animal that can live for more than 165 years. During the first 4 years of life, heliotrope snails grow rapidly, growing an average of more than 2.5 cm per year. With a long "neck" (also known as a straw), the heliotrope snail's body can be more than 90 cm. Meanwhile, the outer shell is usually not up to 20.3 cm long. This is a saltwater mussel native to Puget Sound and is believed to live for at least 160 years.
12. Rougheye Fish
Rougheye is one of the longest-lived fish, they grow very slowly, taking decades to become an adult. The life cycle of a Rougheye can be as long as 200 years, with the longest recorded Rougheye being 205 years. Rougheye usually lives at depths of 170 to 700m below sea level, and in the waters of the Pacific Ocean.
11. Red Sea Urchin
The red sea urchin is the largest species of sea urchin, which can grow up to 25cm. They appeared 450 million years ago, and in their life cycle are usually very few moves, so red sea urchins have many protective spikes. Sometimes they also often gather together and go in search of food, but they crawl quite slowly. There is a special thing that the average life expectancy of red sea urchins is 30 years, but if exceeded they can live to more than 200 years.
10. Bowhead Whale
Some scientists believe that bowhaed whales may be the oldest living mammals 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 as many as four of these whales live between 91 and 172 years.
9. Koi carp
- The poor dog is paralyzed and can’t stand up crying for everyone’s help and doesn’t leave him in this helpless moment
- The moment when the brave loyal dog fought to the last moment sacrificing himself to protect the safety of his owner from the attack of venomous snakes made us extremely emotional and couldn’t hold back his tears me

Although the average lifespan of koi carp is only about 50 years, but a special case has helped this tiny fish to be named in the list of "toughest" living animals on earth. It was a koi fish named Hanako that lived 226 years, from 1751 to 1977. The lifespan of this fish is confirmed by counting the number of veins on its scales, similar to determining the life of a tree based on into the wood grain.
8. Tubeworm Vestimentiferan
This mollusk lives in a protective and fixed shell throughout its life. Vestimentiferan tubeworms have a body length of up to 3m and often live in very large groups, up to thousands of individuals. They usually live in the northern Gulf of Mexico, where the depth is more than 750m below sea level. Vestimentiferan tubeworms grow very slowly, usually they can live more than 250 years.
7. Greenland Shark
These sharks can live up to 200 years. Scientists discovered a 400-year-old case. This has made them the oldest vertebrates in the world. These animals are long-lived because they grow very slowly, about 1 cm per year, and reach old age at 100 years old.
6. Freshwater mussels
While many animals find it difficult to adapt to changing habitats, from climate and geology to many physical, chemical and biological factors change. The freshwater mussels have the ability to adapt quite well when they have to completely change living conditions. Perhaps it is because of this that they can live up to 250 years. Freshwater mussels are commonly found in the Scandinavian peninsula.
5. Tortoise
Turtles are still known as animals with a fairly long lifespan, on average a healthy tortoise can live up to 150 years, but it also depends on different types of turtles. A turtle named Adwaita who lived at a zoo in Kolkata lived for more than 250 years and died from an increasingly severe crack in the shell. Had it not been for that unfortunate accident, perhaps the Adwaita tortoise could have lived much longer.
4. Quahog . Shellfish
This sea scallop is native to the North Atlantic Ocean, it lives at depths from 8 to 396m. To avoid being eaten, they can hide deep on the seabed and live there for a long time without looking for food and oxygen. North Atlantic sea scallops are mollusks with a lifespan of about 400 years, the longest can live to 507 years old. According to research, the reason they live so long is because they contain an unusually high antioxidant content in the body.
3. Antarctic Sponge
Many people mistakenly think that sponges are plants, but in fact they are an inactive animal, moving only 1mm a day. Sponges also have a very slow growth rate, so they have a fairly long life cycle. Common sponges have a lifespan of three to twenty years, with the only species of Antarctic sponges that can live up to 1550 years.
2. Black coral
Corals look like colorful rocks and underwater plants, but they're actually made up of invertebrate exoskeletons called polyps. These polyps continuously multiply and replace themselves by creating a genetically identical copy, which over time causes the coral's exoskeleton structure to grow larger and larger. As a result, corals are made up of many identical organisms rather than a single organism so longevity of the coral is a team effort. Samples of black coral found off the coast of Hawaii are 4,265 years old.
1. Immortal Jellyfish
This jellyfish has the scientific name Turritopsis nutricula, they have a special ability to reverse their life cycle from the adult stage back to the protozoan period and from there continue to develop. This is the only known case of a multicellular organism capable of reversing its life cycle when mating after becoming sexually mature. Theoretically, this process goes on indefinitely, and leads to the jellyfish's immortality.
Like Turritopsis jellyfish, Hydras jellyfish also have the potential to live forever. These invertebrates are largely made up of stem cells, which continuously regenerate through duplication or cloning. Hydras don't live forever in the wild because of threats like predators and disease, but without these external threats, they could be immortal.
