However, sea turtles face increasing threats from climate change, habitat destruction, and human activities. Their unique life cycle and migratory patterns make them particularly vulnerable, yet they remain symbols of resilience.
Every year on 16 JuneWorld Sea Turtle Day‘ is celebrated to raise awareness about Conservation Efforts This is essential to protect these magnificent animals and highlight their importance to the health of the ocean.
Interesting facts about sea turtles
Life expectancy 80 years
Sea turtles have a very impressive lifespan, with many species living between 50 and 80 years. They take two to three decades to mature, and once mature, they continue to actively reproduce for about 10 years.
The temperature of the sand determines their gender
The temperature of the sand where sea turtles lay their eggs plays an important role in determining the sex of the hatchlings. Male sea turtles are born on cooler sand temperatures, while females are born on warmer sand. This temperature-based sex determination is sensitive to climate change, which affects turtle populations in the future.
Shortage of male sea turtles in Florida
Due to record high temperatures in Florida, the sand where sea turtles nest has become too hot. This has led to an alarming trend where the majority of eggs are hatching as females, resulting in a growing shortage of male turtles.
Sea turtles migrate thousands of miles
Sea turtles are known for their extraordinary migrations. For example, the leatherback turtle travels more than 10,000 miles annually across the Pacific Ocean. Loggerhead turtles have been observed traveling nearly 8,000 miles from Japan to Baja. These long-distance migrations are necessary for food, reproduction, and survival.
They play a vital role in the marine ecosystem
Sea turtles are essential for maintaining healthy marine ecosystems. They graze on seagrass beds and coral reefs, preventing overgrazing and promoting biodiversity. By controlling jellyfish and crustacean populations, sea turtles help balance food webs. Their presence ensures the health of the oceans, which benefits many other species.
their shells can’t be retracted
Unlike land turtles, sea turtles cannot retract their heads or fins into their shells. This makes them more vulnerable to predators like sharks and killer whales. Hatchlings and eggs are even more vulnerable to animals like raccoons and seabirds, making protection vital to their survival in the wild.
Human activities pose major threats
Human activities are a major threat to sea turtles. Coastal development reduces nesting sites, while artificial lighting drives hatchlings away from the ocean. Plastic Pollution This also poses a major threat, as many sea turtles mistake the debris for food, often resulting in fatal blockages or entanglements.
There are only 6.5 million sea turtles left
The current global sea turtle population is estimated at 6.5 million, with most species classified as endangered or critically endangered. This decline is primarily due to habitat loss, poaching, and accidental catches in fishing equipment. Conservation efforts are vital to prevent further declines and protect these iconic marine species.
Hawksbill and Kemp’s ridley turtles are critically endangered
Hawksbill TurtlesFamous for their attractive shells, the Kemp’s ridley turtle has a population of only 57,000, making them critically endangered. The Kemp’s ridley turtle, another critically endangered species, is even rarer, numbering only about 10,000. Both species are under serious threat due to climate change and human activities.
Sea turtles thrive during the COVID-19 pandemic
During the COVID-19 pandemic, reduced human activity on beaches gave sea turtles a respite from disruptions. In Florida, where nearly 400,000 sea turtle nests were recorded in 2019, researchers found better nesting success during lockdown in 2020. Fewer people visiting the beach and less trash allowed turtles to thrive without human interference.
Sea turtles have existed for over 100 million years
Sea turtles are among the oldest creatures on Earth, having existed for more than 100 million years. They have survived drastic changes in the planet’s climate and ecosystems over the millennia. However, their adaptability is being tested by the rapid pace of modern climate change and human impacts on the oceans.
They can hold their breath for hours
Sea turtles are highly adapted to life at sea and can hold their breath for up to five hours while resting. When active, they surface every few minutes for air. This ability is essential for their long dives, especially when they are feeding or escaping predators in the deep sea.
Excellent navigation skills
They travel thousands of miles using the Earth’s magnetic field and return to the same beach where they were born and lay their eggs.
Sea turtles help combat climate change
By grazing on seagrass beds, sea turtles play a role in regulating the ocean’s carbon cycle. Seagrass absorbs carbon dioxide and stores it, helping to mitigate the effects of climate change. The health of these underwater meadows depends on sea turtles, as they prevent overgrazing and maintain biodiversity in the marine ecosystem.
Conservation Efforts
Many organizations and governments are working to save sea turtles, such as reducing bycatch in fisheries, protecting nesting sites, and banning plastic waste. Sea Turtle Conservation ProjectIt aims to conserve endangered species, especially the Olive Ridley turtle.
Launched in 1999 by the Ministry of Environment and Forests in collaboration with UNDP, this programme focuses on Indian coastal states, particularly Odisha. It uses satellite technology to monitor nesting areas, protect breeding habitats and promote cooperation at national and international levels for turtle conservation efforts.
