Green Sea Turtles: Guardians of the Ocean’s Legacy

With an estimated 85,000 and 90,000 nesting females, these magnificent creatures confront substantial threats to survival. These include habitat loss, pollution, and climate change, posing significant challenges to their continued existence.

Conservation Status

The conservation status of green sea turtles, which are currently classified as endangered, is a matter of grave concern.

Habitat

They can be found in tropical and subtropical waters worldwide. They prefer shallow waters near coral reefs, seagrass beds, and mangrove swamps, which provide ample food and shelter, essential for their survival. However, the increasing degradation of these habitats poses a significant risk to their long-term viability.

Migration Patterns

Green sea turtles are known for their remarkable migration patterns. They travel long distances between their feeding and nesting grounds, often traversing thousands of miles, returning to sandy beaches in the tropics to lay their eggs. Despite their nomadic lifestyle, these turtles exhibit remarkable fidelity to their nesting sites, returning year after year to continue the cycle of life.

Life Cycle and Behaviour

From their humble beginnings as hatchlings emerging from sandy nests to their epic migrations across oceans, green sea turtles lead fascinating lives filled with adventure and wonder. These remarkable creatures spend much of their lives at sea, feeding on seagrass and algae in coastal waters before returning to the beaches where they were born to lay their eggs. With uncanny accuracy, they travel great distances under instinct and the tides.

Conservation Efforts

Despite their enduring legacy, green sea turtles face numerous threats, including habitat loss, pollution, and climate change. We all must protect and preserve these magnificent creatures for future generations. Through our responsible tourism practices and support for conservation initiatives, we strive to ensure that green sea turtles continue to thrive in their natural habitat for years to come.

Size and Description

Adult green sea turtles grow to impressive sizes, reaching up to 1.5 metres in length and weighing between 68 and 190 kilograms. Despite their large size, they have comparatively small heads and teardrop-shaped shells in dark brown, grey, or olive colours. Their underside is much lighter, ranging from yellow to white, and they possess large paddle-like flippers, ideal for navigating the ocean depths.

Reproduction

The Great Barrier Reef is a vital nesting site for green sea turtles, with genetically separate populations located north and south of Australia’s northeastern and northern shores. Important breeding places, such as Raine Island and Bramble Cay, play a crucial role in the survival of these magnificent creatures. However, increasing human activity and habitat degradation threaten the future of these critical nesting sites.

Diet

Green sea turtles exhibit a diverse diet that evolves as they mature. While young turtles consume meat, including molluscs, jellyfish, and small invertebrates, adults transition to an omnivorous diet. They feed on various marine life, including algae, crustaceans, and fish eggs, with coral reefs and seagrass beds providing essential habitats for their survival.
