The only animal known to be biologically immortal, meaning it can theoretically live forever by reversing its aging process, is the tiny jellyfish Turritopsis dohrnii, also known as the "immortal jellyfish". When stressed, injured, or old, it can transform back from an adult medusa into a juvenile polyp stage, essentially resetting its life cycle to start anew through a process called transdifferentiation.

Which animal can live forever?

In the warm seas of the Mediterranean lives a jellyfish with an extraordinarily rare ability – it can rewind its life cycle. The so-called 'immortal' jellyfish, or Turritopsis dohrnii, can somehow reprogramme the identity of its own cells, returning it to an earlier stage of life.

Which animal has a 1000 year lifespan?

The tubeworm Escarpia laminata that lives in deep sea cold seeps regularly reaches the age of between 100 and 200 years, with some individuals determined to be more than 300 years old. Some may live for over 1,000 years.

Which animal did not have death?

At the top of our immortal animals list is a tiny variety of jellyfish known as Turritopsis doohmii, or more commonly, the immortal jellyfish.

Which animal in the world never dies?

When the medusa the immortal jellyfish (Turritopsis dohrnii) dies, it sinks to the ocean floor and begins to decay.

Immortal Animals: 5 Species That Could Live Forever

Can a Turritopsis dohrnii regenerate after injury?

Turritopsis dohrnii, the so-called "immortal jellyfish," can hit the reset button and revert to an earlier developmental stage if it is injured or otherwise threatened. Like all jellyfish, Turritopsis dohrnii begins life as a larva, called a planula, which develops from a fertilized egg.

What animal is a silent killer?

A "silent killer" animal can refer to predators that hunt stealthily (like leopards, owls, crocodiles) or venomous creatures that don't make loud threats (like the camouflaged stonefish, the venomous slow loris, or the disease-carrying mosquito), with the mosquito often cited as the deadliest due to diseases, while the common krait snake also earns the nickname for its potent neurotoxins. 

Could humans live 200 years?

Based on mathematical models, our longest potential lifespan is around 150 years. But, we know that genetic manipulation of model organisms increases it by up to 100%. So, humans can live up to 244 years.

What animal is pregnant for 4 years?

Did you know the longest brooding period or 'pregnancy' of any known animal is a whopping four and a half years? If you think female African elephants have it tough with their 22-month gestation period, spare a thought for the deep-sea octopus Graneledone boreopacifica.

What animals don't age?

Jellyfish and comb jellies

Turritopsis dohrnii and Turritopsis nutricula, are small (5 millimeters (0.20 in)) species of jellyfish that use transdifferentiation to replenish cells after sexual reproduction. This cycle can repeat indefinitely, potentially rendering them biologically immortal.
