Top 3 Longest Living Animals on Earth
The oldest confirmed person was Jeanne Calment, a 122-year-old Frenchwoman, yet her life expectancy pales in contrast to that of other animals on the planet. Some creatures can live for hundreds or even thousands of years. Surprisingly, there are two species that have been identified as having the potential to live indefinitely. The world’s longest-living animals are listed below.
3). Antarctic Sponge
The Antarctic sponge is a slow-growing multicellular creature found in the chilly waters of the Antarctic Ocean. Some of the sponges discovered here are thought to be over 1,500 years old. Because this organism lacks a protective shell, predators like as turtles and fish can easily hurt or kill them. This just adds to the incredible fact that some of these sponges have survived for so long. Sponge don’t have a digestive, circulatory, or neurological system, relying instead on water movement to thrive. They receive oxygen and nourishment when water passes through them. Waste is also carried away by the river.
A freshwater polyp related to coral, sea anemones, and jellyfish, the hydra is a tiny freshwater polyp. The hydra, like the Turritpsis nutricula jellyfish, has regenerative abilities. When you tear one of these small organisms apart, each piece grows into a new hydra extremely fast. Hydras don’t seem to age in any way. Their bodies are tubular in form, with a venomous tentacle-filled mouth on one end. The hydra paralyses insects and crustaceans with its tentacles before eating them. They only grow to be a little less than an inch long, yet they can eat animals up to twice their own size. These weird animals move about by “somersaulting” or using a cup-like foot or dragging themselves along with their tentacles.
1). Turritopsis Nutricula Jellyfish
Turritopsis nutricula, sometimes known as the “immortal jellyfish,” is a species of Turritopsis. Once sexually mature, this species has the ability to return back to the polyp stage, thereby restarting its existence. The jellyfish does this by allowing its cells to transdifferentiate into different types of cells. Its muscles, for example, may transform into eggs or sperm, allowing life to regenerate. Most Turritopsis perish as a result of being eaten by other animals or contracting a disease while still in the polyp stage. Because their regenerating powers were not discovered until the 1990s, it is unknown how long one of these species lives. Furthermore, it is difficult to observe them in their natural habitat, and the process of life rejuvenation is very quick. It’s practically hard to determine their age accurately because of this.
