1. GREEN SEA TURTLE Marine Biology Presented by Austin and Mike

2. Kingdom: Animalia Phylum: Chordata Class: Reptilia Order: Estudines Family: Cheloniidae Genus: Chelonia Species: Mydas Chelonia Mydas

3. ●Species: there are 7 species: Green Sea Turtle (Chelonia mydas), Hawksbill (Eretmochelys Imbricata), Leatherback (Dermochelys Coriacea), Loggerhead (Caretta Caretta), Flatbacks (Natator Depressus), Kemp’s Ridley (Lepidochelys kempii), Olive Ridley (Lepidochelys olivacea). ●Green Sea Turtles from the Cheloniidae family. ●Turtles evolved in the Mesozoic Era and have scarcely changed since. they took to the sea during this time period. ●can live up to 100 years or more. ●weight: 300-350 pounds (135-160 kg) for adults; hatchlings weight: 0.05 lbs (25 g) ●Weigh up to 400 lbs over all. ●Length: 3 feet (1m.) for adults; others maybe up to 5 feet long. ●hatchlings are 2 inches (50 mm). ●Appearance: top shell (carapace) is smooth with shades of black, gray, green, brown, and yellow; their bottom shell (plastron) is yellowish white.

8. They eat: Algae, jellies, squid, urchins, sea cucumbers, mollusks, prawns, other invertebrates and seaweed. FEEDING

10. Adults: Sharks, whales, and humans. Juveniles and new hatchlings: Crabs, small marine mammals, and shorebirds. PREDATION

11. - Beaches for nesting -Open ocean convergence zones -Coastal areas for "benthic" feeding HABITAT/LOCATION

12. Tropical regions along the equator. Pacific, Atlantic and Indian Ocean. Warmer areas of the oceans. Young, sometimes spend their summer in New England waters.

14. Nesting seasons are at different times around the world. In U.S.-April through October. They Mate in the ocean, males rarely return to land after crawling into the sea as hatchlings Most females return to nest on the beach where they were born (natal beach). Most females nest at least twice during each mating season; some may nest up to ten times in a season. The female turtle crawls to a dry part of the beach and begins to build a "body pit" by digging with her flippers and rotating her body. After the body pit is complete, she digs an egg cavity using her cupped rear flippers as shovels. The egg cavity is shaped roughly like a teardrop and is usually tilted slightly. These may lay up to 200 eggs. REPRODUCTION

15. -Red dots are known major nesting sites -Yellow dots are minor nesting sites

16. - Harvest of eggs and adults (historically, though the practice continues in some areas of the world) -Following artificial lights after hatching -Incidental capture in fishing gear HUMAN IMPACT/THREATS

17. - General threats to marine turtles: Marine debris and environmental contamination -Fibropapillomatosis (disease)
