Due to today’s bad lifestyle and bad food habits, we are surrounded by many diseases in the early days of our life. Which also has a bad effect on our lifespan. This is the region where scientists are engaged in research day and night to increase human longevity. Now the human race may be struggling with the struggle to prolong its life, but there are some such animals around us even today. Which can live for hundreds of years.
Yes, this may sound like a lie, but in reality, it is absolutely true. So let’s meet the 10 longest living animals on earth…

List of Longest Living Animals on Earth
Let us now tell you about such a creature who never dies. Yes, you heard right, the creature named Hydra is really immortal. Actually, Hydra is such a group of small invertebrates, whose body is very soft and it looks like jellyfish.

That’s why they never get old. It has also been found many times when Hydra has regenerated the lost parts of its body.

Black corals are the longest living creatures, living up to several 100 years. In March 2009, such a case also came to light when more than 4000 years old black coral was found. Apart from this, researchers have discovered corals older than 2500 years. It is believed that the enemies of these sea creatures are few and far between due to what scientists consider a major reason for their longevity.
