9 Animals with long lifespan


Animals living under natural conditions rarely approach their maximum possible age because of very high death rates due to infant mortality, diseases, predators, bad weather, habitat destruction, or competition for food and shelter.

Below Is A List Of Animals That Have A Long Lifespan In The World But Believe It Or Not Number 1 Never Dies If Not Killed

9.Cat

Domestic cats live on average 10-15 years.

8.African Elephant 

Lives for 60-70 years.

7.Longfin Eel

Often lives to 60 years. 

6. Pink cockatoo

Oldest recorded: 83 years.

Average adult weight: 0.9 Lbs.

Habitat: Australia, New Guinea, Indonesia, Solomon Islands, and the Philippines.

5.Bowhead whale

Based on the recovery of stone harpoon tips from harvested bowheads, it is evident that bowhead whales live well over 100 years.

With an average lifespan of 177 years, tortoises are considered one of the longest living vertebrates on Earth. One of their oldest known representatives was Harriet, a Galápagos tortoise that died of heart failure in 2006 at the age of 175 at a zoo owned by the late Steve Irwin. Harriet was considered the last living representative of Darwin’s epic voyage on the HMS Beagle. A Seychelles tortoise named Jonathan, at 187, recently made it into the Guinness World Records as the oldest known living land animal.

3. Red Sea Urchin

The red sea urchin (Strongylocentrotus franciscanus) has a life expectancy from 100 to over 200 years. Found only in the Pacific Ocean, primarily along the West Coast of North America and the northern coast of Japan, the red sea urchin lives in shallow, sometimes rocky waters. The red sea urchin avoids extremely wavy areas and stays primarily from the low-tide line down to 300 feet. They crawl along the ocean floor using their spines as stilts.Red

Tuatara are the only surviving members of an order that flourished about 200 million years ago, the Sphenodontia. Essentially, they are living fossils. Tuatara are also among the longest-lived vertebrates on Earth, with some individuals living over 100 years. Found only in New Zealand, tuataras reach sexual maturity after 10 to 20 years and continue growing until they are 35 to 40 years old.

1.Immortal jelllyfish 

Turritopsis dohrnii, also known as the immortal jellyfish, is a species of small, biologically immortal jellyfish found worldwide in temperate to tropic waters. It is one of the few known cases of animals capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual. Others include the jellyfish Laodicea undulata and species of the genus Aurelia.

If a T. dohrnii jellyfish is exposed to environmental stress, physical assault, or is sick or old, it can revert to the polyp stage, forming a new polyp colony. It does this through the cell development process of transdifferentiation, which alters the differentiated state of the cells and transforms them into new types of cells.

Theoretically, this process can go on indefinitely hence living forever, effectively rendering the jellyfish biologically immortal, although in practice individuals can still die. In nature, most Turritopsis dohrnii are likely to succumb to predation or disease in the medusa stage without reverting to the polyp form. However Immortal Jellyfish Never Dies and Lives Forever only if they are not killed by predators or disease in the medusa stage without reverting to the polyp form.
