In a world where the average lifespan for humans is rising, it’s hard to fathom that no one born in the 1800s is still walking among us. The oldest known living person today is Tomiko Itooka from Japan, having celebrated her astounding 116th birthday in October 2023. Born in Osaka in 1908, Itooka has witnessed monumental milestones in history, from World War II to the dawn of the Internet. But while humans like Itooka are spectacular in their longevity, certain animals are scratching our jaws in amazement with their lengthy existence. Here are three remarkable creatures that redefine what it means to survive through the ages.

1. Greenland Shark: The Ancient Ocean Wanderer

The Greenland shark is not just any fish; it holds the title for the longest-living vertebrate known to science, with lifespans that can stretch between 250 to 500 years! Imagine the aquatic adventures these majestic sharks may have undertaken alongside some of history’s great explorers like Ferdinand Magellan in the early 1500s or standing witness to the tragic sinking of the Titanic in 1912. Their secret to such an incredible lifespan lies in various traits: an extremely slow growth rate—hitting sexual maturity at around 150 years—and their ability to thrive in deep, cold waters with low oxygen levels. These adaptations allow them to conserve energy and live a stress-free existence compared to so many others in the animal kingdom.

2. Bowhead Whale: The Giant of the Arctic

With verified lifespans exceeding 200 years, bowhead whales are living legends of the ocean. Some individuals, studied as recently as the 2000s, bore harpoons from the 1800s, showcasing their remarkable ability to evade hunters for over a century. Their secret? A combination of a slow aging process linked to unique genetic traits and extraordinary cellular repair mechanisms that allow them to recover from injuries efficiently. In addition, living in the icy Arctic waters likely slows down their metabolic rates, providing them further longevity. This noble creature not only showcases nature's resilience but also signals the implications of our actions on wildlife conservation as they continue to inhabit the ocean.

3. Tuatara: The Living Fossil of New Zealand

Lastly, we find the Tuatara, a reptile that has remained relatively unchanged for over 200 million years. This small creature can live an impressive 130 to 140 years, which is extraordinary for a reptile of its size (capping out at about 30 inches). With a metabolism that operates at a leisurely pace, tuataras experience less wear and tear on their bodies. Their slow growth ensures that they do not experience the rapid aging often associated with fast-developing species. However, they also face unique challenges, including habitat loss and climate change, factors that could jeopardize their long-term survival. Their specialized adaptations are fascinating, making them more resilient to harsh conditions typical of their island home.

Conclusion: A Window into Survival

While humans celebrate their achievements and longevity, these ultra-surviving animals remind us of the extraordinary lengths nature can go to endure. Each of these species boasts remarkable adaptations that guarantee their survival through centuries. As we dive deeper into understanding these creatures, let us also reflect on our responsibilities as stewards of the Earth, ensuring these living marvels continue to roam our planet well beyond our lifetimes. So, what do you think – can we ever hope to learn the secrets to such longevity from our animal counterparts?
