They can easily prove that the overall lifespan of humans is nothing when we calculate theirs.
Few animals can live much longer than others, there are a few animals who just discard this longest-living fact. Because they are able to avoid death. Animals like immortal jellyfish don’t need the blessings of Aurora, the Greek goddess of the dawn to be immortal.
Unlike Tithonus they can evolve from a mature stage to an immature polyp. So it can easily be said that beyond our knowledge, there are a handful of animals around us before whom human life may seem short. From birds to marine life, they exist throughout different habitats.
Immortal Jellyfish, probably the first immortal living creature
Immortal is just not a word suitable for literature and this living being has proved that very well. It is a type of jellyfish that can continue its life cycle by evolving itself from a mature state to an immature polyp, meaning it is capable enough to live forever. While there are some threats like predators and a few unnatural causes of death, it has managed to save itself. If it experiences any threat in the environment, it is capable enough to revert itself to its original polyp stage. In order to change the location, it can ride at the bottom of cargo ships and move to a safer location.
Ocean Quahog
Ocean Quahog is mostly found in the Western Atlantic Ocean, in Newfoundland and North Carolina. They can easily bury themselves at the bottom of the ocean floor and can filter the water at a great level (1 gallon per hour). Their average lifespan is around 400 years. The oldest living Quahog has lived for 507 years. It is also the oldest noncolonial animal in the world.
Greenland Shark
They are the deep sea dwellers who move very slowly at a rate of around 1 km per hour. These sharks are spotted as deep as 7200 feet below sea level. They are considered the longest-living vertebrate. The process of growth and maturity is very slow as they grow only 1cm each year. In this way they become sexually mature at around 100 years. According to the findings, scientists have concluded that the average age of a Greenland Shark can be more than 350 years.
