The 10 Longest-Living Animals: Nature’s Most Resilient Creatures

As humans, reaching 100 years old can be quite the milestone. However, in the animal kingdom, this is just the beginning for some species! From the deepest oceans to the highest mountains, there are creatures that defy the passage of time, living for hundreds—even thousands—of years. Here is a top 10 list of the animals with the longest documented lifespans. The list starts with the “shortest” long-lived species and moves towards the ultimate record holder.

#10: Giant Tortoise – up to 190 years

Giant tortoises, especially the Galápagos species, are renowned for their slow lifestyle and remarkable lifespans. Some individuals have been documented to be over 180 years old. Their peaceful existence and lack of natural predators contribute to their longevity.

#9: Red Sea Urchin – around 200 years

This ocean-dwelling creature, found along the western coast of North America, rarely lives less than 100 years. Red sea urchins exhibit almost no age-related decline, making them an intriguing subject for research into aging.

#8: Koi Fish – up to 225 years

While many koi fish in captivity live 30-50 years, there are documented cases of individuals living over 200 years. The most famous, “Hanako,” reportedly lived to 226 years old in Japan. Their lifespan heavily depends on care and water quality.

#7: Greenland Shark – up to 400 years

The Greenland shark is not only one of the longest-living shark species—it’s also the longest-living vertebrate. With an extremely slow growth rate and a lifespan of up to 400 years, these sharks glide slowly through the cold Arctic waters with no sense of urgency.

#5: Ocean Quahog Clam – up to 507 years

This modest sea inhabitant, known as the “Ocean quahog,” surprises with its ability to live over 500 years. The oldest known specimen was named “Ming” because it was born while the Ming dynasty reigned in China.

#4: Black Coral – up to 4,000 years

Black coral grows in the deep sea, forming colonies that can live for thousands of years. Researchers have dated certain colonies to be at least 4,000 years old, making them some of the oldest living organisms on the planet.

#3: Glass Sponge (Antarctica) – up to 10,000 years

In the cold waters around Antarctica live glass sponges, which grow so slowly that their lifespan is measured in millennia. Some estimates suggest they can live up to 10,000 years, making them some of the oldest multicellular organisms on Earth.

#2: The Colony “Pando” – over 80,000 years

This colony of aspen trees in Utah, USA, is technically one organism connected by a single root system. While individual trees die and regenerate, the entire clone colony has existed for up to 80,000 years. It continues to grow and remains genetically identical through time and space.

#1: The Sea Grass ‘Posidonia oceanica’ – up to 200,000 years

The world record for the longest-living organisms goes to a colony of sea grass in the Mediterranean. This plant form has existed as a single cohesive genetic unit for up to 200,000 years. It propagates clonally and has survived climate changes, ice ages, and human encroachment.
