Introduction: The green turtle weighs approximately 150 jin, accounting for only a fraction of its juvenile population. Generally, green turtles migrate from June to September each year, returning to the shore to lay eggs. At night, female turtles slowly crawl onto the beach to find suitable locations and dig nests for laying eggs, which usually range from 50 to 200 (Figure 2). After laying, they cover the eggs with sand and incubate naturally in the warm and humid sand, usually taking about 49 to 60 days for the young turtles to hatch and crawl into the sea. Protection staff assist them in returning to the sea (Figure 3). As a national second-class protected animal and an internationally protected species, green turtles are of great significance.
