19 Living Creatures That Have Survived for Hundreds of Years
Life spans in the animal kingdom show remarkable diversity. While humans celebrate reaching 100 years as an extraordinary achievement, some creatures on our planet consider a century merely the beginning of their journey. These ancient organisms challenge our understanding of aging and mortality with their exceptional longevity.
Let’s explore 20 living creatures that have survived for hundreds of years, defying time in ways that seem almost magical to us short-lived humans.
Greenland Shark
The Greenland shark holds the title for the longest-living vertebrate, with lifespans reaching an astonishing 400 years. These cold-water dwellers grow at a glacial pace of less than one centimeter per year, reaching maturity around age 150.
Their secret to longevity likely lies in their extremely slow metabolism, perfectly adapted to the frigid Arctic waters they call home.
Giant Tortoise
Giant tortoises are famous for their remarkably long lives, regularly reaching 150-200 years in the wild. Jonathan, a Seychelles giant tortoise born around 1832, is currently the oldest known living land animal at approximately 190 years old.
These gentle giants maintain slow, steady metabolic rates and possess impressive cellular repair mechanisms that help them resist aging.

Ocean Quahog Clam
The ocean quahog clam puts most other long-lived creatures to shame with verified specimens reaching over 500 years of age. One famous example, nicknamed Ming, was determined to be 507 years old when scientists unfortunately killed it during the age verification process.
These unassuming mollusks grow extremely slowly in cold North Atlantic waters, adding just one growth ring to their shells annually.
Bowhead Whale
Bowhead whales routinely live beyond 200 years, making them the longest-living mammals. Scientists discovered their impressive age by finding 19th-century harpoon fragments embedded in living whales and through analysis of eye tissue proteins.
Their longevity likely stems from extremely efficient DNA repair mechanisms and low body temperature that reduces cellular damage over time.
Tubeworm
Deep-sea tubeworms living near hydrothermal vents can survive for over 300 years in one of Earth’s most extreme environments. These remarkable creatures have no digestive system and rely on symbiotic bacteria that convert chemicals from the vents into nutrients.
Their incredibly slow metabolism and stable deep-sea habitat contribute to their extended lifespan.

Great Basin Bristlecone Pine
The Great Basin bristlecone pine stands as the oldest known non-clonal organism on Earth, with some specimens exceeding 5,000 years of age. These hardy trees survive in harsh, high-altitude environments where few competitors exist.
Their dense, resin-rich wood resists decay, insects, and fungal attacks, while their slow growth conserves energy over millennia.
Antarctic Sponge
Antarctic sponges can live for over 10,000 years in the frigid waters surrounding Antarctica. These simple organisms grow at rates of less than 0.2 inches per century, making them among the slowest-growing creatures on Earth.
Their minimal energy requirements and simple cellular organization contribute to their exceptional longevity in the stable, cold waters they inhabit.
Red Sea Urchin
Red sea urchins routinely live for 200 years, with some individuals potentially reaching 400 years. These spiny ocean dwellers show almost no signs of aging throughout their long lives and can reproduce until death.
Their cells appear to maintain regenerative capacity indefinitely, making them valuable subjects for aging research.

Aldabra Giant Tortoise
The Aldabra giant tortoise regularly lives beyond 150 years in its native habitat of the Aldabra Atoll. Their slow metabolism, efficient digestive systems, and lack of predators contribute to their impressive lifespan.
Unlike many animals, these tortoises continue growing throughout their lives, albeit at an increasingly slower rate as they age.
Rougheye Rockfish
The rougheye rockfish can live for over 200 years in the deep waters of the North Pacific. These slow-growing fish take approximately 25 years to reach sexual maturity and continue reproducing throughout their long lives.
Their deep-water habitat provides stable temperatures and protection from many predators, factors that likely contribute to their extended lifespan.
Black Coral
Black coral colonies can survive for over 4,000 years in the deep ocean, making them some of the oldest living animals on the planet. These colonial organisms grow at an incredibly slow rate of about 0.04 inches per year.
Their remarkable longevity stems from slow metabolic processes and the ability to continuously replace individual polyps within the colony.

Hydra
The tiny freshwater hydra possesses biological immortality, potentially living indefinitely under ideal conditions. These small relatives of jellyfish continuously renew their cells and show no signs of aging or increased mortality over time.
Their stem cells have unlimited regenerative capacity, allowing them to essentially reset their biological clock continuously.
Glass Sponge
Glass sponges can live for more than 10,000 years on the ocean floor, making them among the oldest living animals. These ancient creatures filter feed in deep, cold waters where disturbances are minimal.
Their silica skeletons grow extremely slowly, adding less than a millimeter per year as they patiently filter the passing water currents.
Lake Sturgeon
Lake sturgeon can live beyond 150 years in the freshwater systems of North America. These living fossils have remained largely unchanged for over 200 million years, with their ancient genetics potentially contributing to their longevity.
They grow rapidly in their early years but then slow dramatically after reaching maturity, conserving energy for their extended lifetime.

Eastern Box Turtle
Eastern box turtles commonly live 100 years or more in their native woodland habitats. Their slow metabolism and protective shells provide advantages for long-term survival.
These turtles can also lower their metabolic rates dramatically during cold periods, effectively pausing their biological clocks during hibernation and extending their overall lifespan.
Lamellibrachia Tubeworm
The Lamellibrachia tubeworm can live over 250 years in the cold, stable environment of deep-sea methane seeps. These fascinating creatures lack mouths and digestive systems, instead housing symbiotic bacteria that provide nutrients.
Their extremely low energy demands and slow growth rate of less than 1 inch per decade contribute to their exceptional longevity.
Orange Roughy
Orange roughy fish can live beyond 150 years in the deep waters they inhabit. These slow-growing deep-sea dwellers take approximately 30 years to reach sexual maturity.
Their long lifespan represents an evolutionary adaptation to deep ocean environments where food can be scarce and reproductive opportunities limited.

American Lobster
American lobsters can potentially live for more than 100 years when spared from predators and fishing. Unlike most animals, lobsters continue to grow throughout their lives and maintain reproductive capabilities into old age.
Their cells produce an enzyme called telomerase that helps prevent the shortening of telomeres, a common cause of aging in other species.
Freshwater Pearl Mussel
Freshwater pearl mussels routinely live beyond 100 years, with some European specimens reaching over 200 years of age. These filter feeders grow extremely slowly after reaching maturity and can essentially enter a state of suspended animation during harsh conditions.
Their simple body structure and low energy lifestyle allow them to persist for centuries in stable river habitats.
Time’s True Masters
The extraordinary creatures detailed above demonstrate nature’s remarkable diversity in approaches to longevity. From the cellular immortality of hydras to the millennial lifespans of bristlecone pines, these organisms have developed fascinating adaptations to extend their time on Earth.
Their existence reminds us that our human perspective on time represents just one brief way of experiencing life in a world where some inhabitants measure their lives not in years, but in centuries or even millennia.
