The thing to note is that apart from the macaw, all the rest are water-dwelling animals.
After that there are some immortal like animals :——
- Turritopsis dohrnii
This jellyfish species, apparently lacks two most important organs of any animal’s body: Brain and heart. According to biologists, such jellyfish don’t turn old and die like almost all other living beings. They simply live up to a certain age and then start getting younger, finally going back to their original state of glory. Their lifespan simply follows a vicious cycle, young to old and back to young again. However, researchers are yet to know exactly why these jellyfish replenish on their own. These species that survive in tropical waters only occasionally die due to illness or predators.
2. Antarctic Sponge
The Antarctic Sponge has made its name in the Guinness Book of World Records for its incredible longevity. This happens predominantly due to their excessively slow growth and cold natural habitat. One of the very few companions of the penguins, Antarctic Sponge lives in the polar climate of the world’s coldest continent Antarctica. It is presumed to live as long as 5000 to 15000 years, by simply reducing their degree of metabolism. This sponge grows only 0.2 mm in length annually, and lives 200m under ice cold water, where sunlight can’t enter
