World Turtle Day

What Is World Turtle Day?

Every year on May 23, the world observes "World Turtle Day." It was established in 2000 by American Tortoise Rescue, a US nonprofit organization. The day aims to deepen knowledge of and respect for turtles and tortoises, and to encourage conservation efforts to protect these threatened animals and the natural habitats they depend on. Its goal is simply to "give turtles and tortoises a chance to survive and thrive."

Historical Facts About These Ancient Survivors

Turtles are true "evolutionary success stories," having survived since the age of dinosaurs with remarkably little change to their form.

• Over 200 million years of history: Fossils of turtle ancestors have been found in rock layers dating back roughly 220 million years, to the Triassic period. As a biological fact, turtles witnessed the entire rise and fall of the dinosaurs while surviving through their unique evolutionary strategy: the shell.
• Record-breaking lifespans: An Aldabra giant tortoise named Adwaita is recorded to have lived to an estimated 255 years old. As a matter of fact, turtles rank among the longest-lived vertebrates on Earth, symbolically connecting life across generations.

The Science Behind Shells and Longevity

A turtle's remarkable resilience is rooted in highly efficient anatomical and physiological features.

• The shell is an "immovable skeleton": A turtle's shell is actually formed from fused, modified ribs and spine. Unlike other animals, turtles cannot "take it off." This rigid exoskeleton not only defends against predators but also functions as a calcium reserve and a buffer against lactic acid buildup—scientifically supporting survival in harsh environments.
• Extremely efficient metabolism: Turtles have very low metabolic rates, allowing them to survive long periods on minimal energy. As a matter of fact, some species can absorb oxygen through their skin and cloaca during hibernation, possessing a specialized physiological mechanism that sustains heart function even in low-oxygen conditions.

Fascinating Facts About Turtles

• "Temperature" determines sex: In many sea turtle species, the sand temperature during egg incubation actually determines the hatchling's sex—generally, warmer temperatures produce females and cooler temperatures produce males. Scientists are increasingly concerned about how global warming may be skewing turtle sex ratios.
• Remarkable navigation skills: Sea turtles can return with precision to nesting grounds thousands of kilometers away. As a matter of fact, they possess a magnetic sense in their brains that lets them navigate the open ocean using Earth's magnetic field like a built-in map.
• Even the shell has nerves: Blood vessels and nerves run through a turtle's shell. If it's struck or scratched, the turtle feels pain—meaning the shell isn't just a "shield" but also part of a sensitive sensory organ.
• The state of endangered species: Of the more than 300 turtle and tortoise species worldwide, more than half are reported by the IUCN (International Union for Conservation of Nature) to be at risk of extinction, largely due to the pet trade, habitat destruction, and plastic pollution.
• A cultural symbol of longevity: Across East Asia, including Japan, there's an old saying: "The crane lives a thousand years, the turtle ten thousand." This cultural reverence connects neatly with the biological reality of turtles' extraordinary lifespans, and the saying is still passed down today.

Ideas for World Turtle Day

• Watch a documentary about turtle ecology and conservation. Reflecting on creatures that have survived 200 million years can offer a thoughtful perspective on the sustainability of our own planet.
• Take action to reduce plastic use. Sea turtles often mistake plastic bags for jellyfish and eat them, a genuinely serious problem. Something as simple as using a reusable bag can directly help protect ocean life.
• Try practicing a "slow life." Like a turtle's steady pace, step back from a world obsessed with efficiency, take a deep breath, and check in with where you are. It's a healthy way to reset any anxiety from the new fiscal year.
• Visit a zoo or aquarium and observe turtles up close. Watching their calm presence and deliberate movements can teach you the "quiet strength" needed to endure a harsh world—and offer hints for building your own resilience.

Carrying the Weight of Ages, a Steady Step at a Time—Bringing Comfort to a Restless Heart

May 23 is a day to appreciate the value of "living at your own pace," something turtles model so well in a world obsessed with speed. No matter how times have changed, turtles have steadily and gracefully carried life forward. As the new fiscal year gets underway, are you comparing yourself to others, or exhausted by impossibly high standards? Today, picture a turtle carrying its heavy shell, moving forward one step at a time. Arriving quickly isn't everything—it's the accumulation of small steps that eventually builds a 200-million-year history. You're doing fine at your own pace. Plant your feet firmly on the ground today, and keep going on your own journey.
