1. Jellyfish (Turritopsis nutricula)

The ¨immortal¨ jellyfish, Turritopsis nutricula, is considered to be one of the most incredible animals in the world. This jellyfish is to the Caribbean and does not measure more than a mere 5mm. This animal is considered to be immortal, defying the concept of death.

But what process converts this jellyfish into such an eternal species? This jellyfish is capable of reversing its aging process. Simply put, it is genetically capable of returning to its form as a polyp (baby). Therefore, once it reaches old age, or a stage of which death nears, it reverses its aging process and dodges death.

2. The Sponge (Porifera)

Sponges, otherwise known as, Porifera, are primitive and beautiful animals. Although many people believe that they are plants, this is not the case. We can find these sponges in almost any ocean in the world. They are incredibly resistant and can withstand cold temperatures and depths up to 5,000 meters. These sea creatures were the first to branch and are a common ancestor of most animals. In addition, they also have an impact on water filtration.

These animals existed 542 million years ago and appear to be the longest living animals in the world, apart from the immortal jellyfish. In fact, the oldest Scolymastra joubini is estimated to have lived up to 13,000 years. These Sponges are able to experience this longevity thanks to their extremely slow growth and cold water environment.

3. The Ocean quahog (Arctica islandica)

The Ocean quahog (Arctica islandica) is the longest living mollusk that exists. This mollusc was infact recorded by accident, when a group of biologists decided to study "Ming". Ming, who originated from the coast of Iceland, is considered the oldest clam in the world. It unfortunately died at 507 years old, due to the clumsy manipulation of one of his observers. This mollusk was born about 7 years after the discovery of America by Christopher Columbus and during the Ming Dynasty.

4. The Greenland shark (Somniosus microcephalus)

This incredible creature lives in the frozen depths of the Antarctic, Pacific and Arctic Oceans. The Greenland shark (Somniosus microcephalus) is the only shark with a soft bone structure and can reach 7 meters in length. It is a predator that, fortunately, has not been killed off by man. This is due to the fact that it is not very dangerous and lives in places humans can barely reach.

Due to the fact that this animal is very difficult to find and incredibly rare, its information is minimal. A group of scientists recently claimed to have found a member of this species at 329 years old, making it the longest living vertebrate in the world.

5. The Bowhead Whale (Balaena mysticetus)

The Bowhead Whale (Balaena mysticetus) is completely black in color, with the exception of its chin, which portrays a beautiful white hue. A male bowhead whale can measure between 14 and 17 meters and females can reach up to 16 or 18 meters. These incredibly large animals can weigh between 75 and 100 tons. In addition to their jawdropping size, they are incredibly fascinating due to their longevity, capable of living up to 211 years old.

Scientists are incredibly intrigued by this unlikely longevity. The reason for this is because, an animal of such a large size has 1000 times more cells than humans, however, still manages to maintain the ability to avoid cancer. Based on the decoding of the animal genome, researchers believe that this animal has managed to create mechanisms to prevent not only cancer, but also some neurodegenerative, cardiovascular and metabolic diseases.
