Living for many years, in addition to being a desire for humans, for now, is also for animals. There are those that are equipped with features to slow down or reverse the aging process. Long-lived animals are usually those that live in aquatic environments. In this way, scientists studied the maximum lifespan of some species from the biology.

Check out some animals that have long life in nature below:
- Hydra
Hydra is part of a group of small invertebrates characterized by being immortal. These animals' stem cells continually regenerate through duplication or cloning, so they don't deteriorate as they age. The only chance they die is due to threats from predators or disease.
- glass sponge
Glass sponges are animals formed by colonies similar to corals. They are found in the deep ocean and have glass-like skeletons. They belong to the Monorhaphis species and live for about 10,000 years.
- quahog shellfish
They live in the North Atlantic Ocean. A quahog clam was found off the coast of Iceland in 2006 and was already 507 years old. They live this long because Ocean Quahog has a slower metabolism and therefore grows more gradually.
- Greenland shark
These sharks live in the depths of the Arctic and North Atlantic oceans. They have a length of up to 7.3 meters. The largest studied to date, according to scientists, is about 392 years old.
However, these vertebrate sharks can live up to 512 years, making them the longest-lived sharks on Earth.
- Seychelles giant tortoise
According to scientists, the oldest living land animal is the Seychelles giant tortoise. Studies reveal that she is over 190 years old and lives on the island of Saint Helena in the South Atlantic Ocean.
Due to its ability to kill damaged cells that deteriorate with age, it is able to live for many years.
