<P> Nesting grounds are found all along the Mexican coast . These turtles feed in seagrass pastures in the Gulf of California . Green turtles belonging to the distinct Hawaiian subpopulation nest at the protected French Frigate Shoals some 800 kilometers (500 mi) west of the Hawaiian Islands . In the Philippines, green turtles nest in the Turtle Islands along with closely related hawksbill turtles . Indonesia has a few nesting beaches, one in the Meru Betiri National Reserve in East Java . The Coral Sea has nesting areas of world significance . The Great Barrier Reef has two genetically distinct populations; one north and one south . Within the reef, twenty separate locations consisting of small islands and cays were identified as nesting sites for either population of C. mydas . Of these, the most important is on Raine Island . Major nesting sites are common on either side of the Arabian Sea, both in Ash Sharqiyah, Oman, and along the coast of Karachi, Pakistan . Some specific beaches there, such as Hawke's Bay and Sandspit, are common to both C. mydas and L. olivacea subpopulation . Sandy beaches along Sindh and Balochistan are nesting sites . Some 25 kilometers (16 mi) off the Pakistani coast, Astola island is another nesting beach . </P> <P> On 30 December 2007, fishermen using a hulbot - hulbot (a type of fishnet) accidentally caught an 80 kg (180 lb), 93 cm (37 in) long and 82 cm (32 in) wide turtle off Barangay Bolong, Zamboanga City, Philippines . December is breeding season near the Bolong beach . </P> <P> Green sea turtles move across three habitat types, depending on their life stage . They lay eggs on beaches . Mature turtles spend most of their time in shallow, coastal waters with lush seagrass beds . Adults frequent inshore bays, lagoons and shoals with lush seagrass meadows . Entire generations often migrate between one pair of feeding and nesting areas . Green sea turtles, Chelonia mydas, are classified as an aquatic species and are distributed around the globe in warm tropical to subtropical waters . The environmental parameter that limits the distribution of the turtles is ocean temperatures below 7 to 10 degrees Celsius . Within their geographical range, the green sea turtles generally stay near continental and island coastlines . Near the coastlines, the green sea turtles live within shallow bays and protected shores . In these protected shores and bays, the green sea turtle habitats include coral reefs, salt marshes, and nearshore seagrass beds . The coral reefs provide red, brown, and green algae for their diet and gives protection from predators and rough storms within the ocean . The salt marshes and seagrass beds contain seaweed and grass vegetation, allowing ample habitat for the sea turtles . </P> <P> Turtles spend most of their first five years in convergence zones within the bare open ocean that surround them . These young turtles are rarely seen as they swim in deep, pelagic waters . Green sea turtles typically swim at 2.5--3 km / h (1.6--1.9 mph). </P>
