Green Sea Turtle

Scientific Name: Chelonia mydas
Common Name: Green Sea Turtle

  • They are called green sea turtles because of the colour of their shell and the green fat located under their shell.
  • They can live up to 90 years in the wild.
  • They lay about 100 eggs at a time, however on average only one of the eggs survives to adulthood.


Did you know?

  • Green sea turtles' face many threats, which include their natural predators like sharks and killer whales. However, they have recently been suffering increasing threats due largely to human impact, in the form of hunting, pollution, and climate change.
  • The hatchlings’ sex is determined by the temperature in their nest, with warmer temperatures favouring female hatchlings. Climate change affects the turtles by warming the temperature of the beach that sea turtle eggs are laid in, which in turn affects the outcome of their sex and overall male / female population balance. 
  • The three green sea turtles currently at COEX Aquarium were born on April 2017 at Aqua Planet Yeosu.

Endangered Species

Green sea turtles are listed as an endangered species by the International Union for Conservation of Nature (IUCN) and CITES, and protection measures are currently in place in most countries. Therefore, collecting, harming, and slaughtering of turtles is currently prohibited.
