About World Sea Turtle Day
World Sea Turtle Day takes place every year on 16 June. It is a global awareness day dedicated to the conservation of sea turtles, the threats they face, and the work being done to protect these ancient marine reptiles. The date was chosen to mark the birthday of Dr Archie Carr, the biologist widely regarded as the father of sea turtle science.
What is World Sea Turtle Day?
World Sea Turtle Day is an annual observance that raises awareness of the seven species of sea turtle and the dangers threatening their survival. It encourages people to learn about turtle biology, support conservation organisations, and take practical action to reduce the harm caused by plastic pollution, fishing gear, coastal development, and climate change. The day is promoted by conservation groups including the Sea Turtle Conservancy and forms part of the wider Sea Turtle Week campaign, a coordinated effort by marine charities around the world. It is observed internationally, from nesting beaches in Costa Rica and Florida to coastlines across the Mediterranean, Australia, and South East Asia.
When is World Sea Turtle Day?
World Sea Turtle Day falls on Tuesday, 16 June 2026. The date is fixed and does not change from year to year, so it is always observed on 16 June regardless of the day of the week. It was deliberately set to coincide with the birthday of Dr Archie Carr, who was born on 16 June 1909. World Sea Turtle Day should not be confused with World Turtle Day, a separate observance on 23 May that covers all turtle and tortoise species rather than marine turtles specifically.
Why World Sea Turtle Day Matters
Sea turtles are among the oldest creatures on Earth, having existed in a recognisable form for more than 110 million years, yet many populations have collapsed within living memory. Of the seven sea turtle species, six are listed by the IUCN Red List as vulnerable, endangered, or critically endangered. Green turtle numbers are estimated to have fallen from around 91 million historically to roughly 30,000 nesting females, while hawksbill populations have dropped from millions to fewer than 30,000. Turtles play a vital role in ocean health: they graze seagrass beds, help keep coral reefs balanced, and move nutrients between land and sea. Protecting them protects the wider marine ecosystems that millions of people depend on for food and livelihoods.
How to Get Involved in World Sea Turtle Day
There are many ways to mark the day and support sea turtle conservation, whether you live by the coast or hundreds of miles inland.
- Join a beach clean – Discarded fishing nets, plastic bags, and litter trap turtles and pollute nesting beaches. Joining or organising a clean-up removes hazards directly from their habitat.
- Cut down on single-use plastic – Around eight million tonnes of plastic enter the oceans each year, and an estimated one in two sea turtles has ingested plastic after mistaking it for jellyfish. Reducing your plastic use helps tackle the problem at source.
- Donate to a conservation charity – Organisations such as the Sea Turtle Conservancy and MarineBio fund nesting site protection, satellite tracking, and rescue work that depends on public support.
- Adopt a turtle symbolically – Many charities offer symbolic adoptions that fund research and provide updates on a real tagged turtle, making a memorable gift for children.
- Choose sustainable seafood – Bycatch in fishing gear is a leading cause of turtle deaths. Checking that the seafood you buy is responsibly sourced reduces demand for harmful fishing methods.
- Learn and share the facts – Read about the seven species and the threats they face, then share what you learn online to widen the day’s reach.
- Respect nesting beaches – If you live near or visit a nesting coastline, keep beaches dark at night, avoid disturbing nests, and follow local guidance, as bright lights can disorientate hatchlings.
- Visit a rescue or research centre – Accredited turtle hospitals and aquariums offer the chance to learn about rehabilitation and support their work through your visit.
History of World Sea Turtle Day
World Sea Turtle Day grew out of the conservation movement that gathered pace in the late twentieth century, when scientists began to document the steep decline in sea turtle populations. The day was created to honour Dr Archie Carr, an American zoologist born on 16 June 1909, who devoted his career to the study and protection of sea turtles and is recognised as the founder of sea turtle biology.
Carr’s long-term research at Tortuguero in Costa Rica, supported by the National Science Foundation, became one of the longest and most intensive studies of an animal population ever undertaken. More than 35,000 adult female green turtles were tagged at his research station, transforming scientific understanding of how turtles migrate, nest, and navigate. In 1959 he helped found the Caribbean Conservation Corporation, now known as the Sea Turtle Conservancy, the world’s oldest sea turtle research and conservation organisation.
By choosing his birthday as the focus for the observance, conservationists ensured that the day celebrates both the animals and the scientific legacy that underpins efforts to save them. World Sea Turtle Day now sits within Sea Turtle Week, a broader awareness campaign that runs in mid June and brings together aquariums, charities, and researchers around shared conservation messaging.
