The Great Barrier Reef is home to a significant population of Green Sea turtles, also known as Chelonia mydas. These majestic creatures are one of the seven species of sea turtles found worldwide and are distinguished by their olive-green coloration and heart-shaped shells. Green Sea turtles play a vital role in maintaining the health of the reef ecosystem, as they graze on seagrass beds, helping to keep them healthy and productive. Additionally, they contribute to nutrient cycling by depositing their eggs on sandy beaches, which in turn nourish the coastal ecosystem. Green Sea turtles are also an iconic symbol of conservation efforts on the Great Barrier Reef, as they face threats from habitat loss, pollution, climate change, and incidental capture in fishing gear. Efforts to protect and conserve Green Sea turtles include habitat preservation, nesting site monitoring, and measures to reduce human impact, such as turtle-friendly fishing gear and marine protected areas. By safeguarding these ancient and beloved creatures, we help ensure the long-term health and sustainability of the Great Barrier Reef ecosystem.
