The animal has the ability to

With continuous regeneration, water is the only animal that is not affected by the aging process.

In ancient Greek mythology, the Hydra is a multi-headed monster capable of growing two new heads for each lost head. In real life, this species called Hydra also has persistent vitality. A new study shows that hydra, or freshwater cavity, seems to be able to live immortally without aging.

According to Live Science, water is a group of invertebrates that look like tiny tubes with tentacles reaching out at one end. They are only about 10mm long and eat smaller animals living in the water.

Water is famous for its regeneration ability. According to research author Daniel Martinez, biologist at Pomova University, California, USA, most of the body's cells of this species are stem cells. The cells can divide continuously and are different from every cell type in the body. In humans, this type of cell appears only in the first few days of embryonic development. In contrast, water is constantly rejuvenating the body with new cells.

In 1998, Martinez and his colleagues published a study describing they found no signs of aging in adult hydration for four years. To detect the aging process, scientists consider mortality and fertility decline in long-term water. In the 1998 study, they were unable to determine whether the fertility of aquatic animals declined with age.

In a new study published Dec. 7 on Pomova University website, Martinez's group created small paradise islands for 2,256 watermelons. They want to provide ideal living conditions for animals. Each individual is in a separate plate, with water changing three times a week and food is fresh sea shrimp.

After 8 years, researchers found no signs of aging in aquatic animals that were raised. The annual death rate remains the same in 1/167 aquatic animals, regardless of age. Similarly, the number of aquatic species with fertility is still 80%, while the remaining 20% ​​is influenced by experimental conditions."I am sure a aquatic individual can live immortally in the right conditions," Martinez said.

In natural environments, plagues, predators and water pollution often kill water before they reach immortality. Hydrological research can help scientists figure out why most animals are aging.

"I hope this research will inspire scientists to take a closer look at immortality," Martinez said.
