-​​​​Green Sea Turtle (Chelonia mydas)


The green sea turtle is the second largest after the leatherback. They can weigh up to 500 lbs (225 kg) and reach four feet (1.2 m) in length. The adult is an herbivore, dining on sea grasses, seaweeds, algae and other forms of marine plant life. Their beak is sharp and finely serrated, perfectly adapted for grazing in seagrass beds and scraping algae off of hard surfaces.

Chelonia mydas

Diet

  • Juveniles: Omnivorous, feeding on jellyfish, crabs, shrimp, sponges, molluscs, and other marine invertebrates, as well as algae.

  • Adults: Primarily herbivorous, grazing on seagrasses and marine algae, making them the only sea turtle whose adult diet consists mainly of plants.

  • Their grazing helps maintain healthy seagrass meadows, which serve as important nursery habitats for many marine species.

Range

  • Found in tropical and subtropical oceans worldwide.

  • Along the eastern Pacific, it occurs from southern California through the Gulf of California, the Pacific coast of Mexico, Central America, and South America.

  • Common in the coastal waters of Guerrero, including the Zihuatanejo region, where juveniles forage in bays, estuaries, and seagrass habitats.

  • Several beaches along Mexico's Pacific coast are important nesting sites.

Habitat

  • Inhabits coastal bays, lagoons, estuaries, coral reefs, seagrass meadows, mangrove channels, and nearshore waters.

  • Juveniles spend their early years in the open ocean before moving into shallow coastal feeding areas.

  • Adult females return to sandy beaches to lay their eggs, often travelling thousands of kilometres to the same nesting beaches where they hatched.

Size

  • Carapace length: 80–120 cm (31–47 in)

  • Weight: 110–190 kg (240–420 lb), with exceptionally large individuals exceeding 250 kg (550 lb).
