Green sea turtles (Chelonia mydas) is a species of large sea turtle of the family Cheloniidae in the genus Chelonia, which belongs to ocean migratory species. Their habitat range extend throughout tropical and subtropical seas around the world. Green sea turtles feed on seaweed and large algae. Occasionally, they also feed on fish or invertebrates. Most mature sea turtles return to their birth places to mate and lay eggs. Each female lays 1 to 7 nests per spawning season, with about 110 to 130 eggs per nest. After the turtles hatch, it takes 20 to 50 years to become sexually mature, and only one of the 1,000 hatchlings gets to become adult. Therefore, their population is easily affected by human factors, such as improper coast development and bycatch. Due to their decreasing population, green sea turtles are currently rated by International Union for Conservation of Nature and Natural Resources (IUCN) as endangered species (EN). Taiwan also listed them as first class protected wild animal.

Most green turtles return to their birthplaces to breed and spawn, so the conservation of spawning habitats is critical to the survival of green sea turtles. Dongsha Atoll National Park has been committed to protect local marine biodiversity since establishment. The result of recording new-born green sea turtles is an important milestone for Marine National Park Headquarters.
