Green sea turtle in the context of "Cheloniidae"

A flipper is a broad, flattened limb adapted for aquatic locomotion. It refers to the fully webbed, swimming appendages of aquatic vertebrates that are not fish.

In animals with two flippers, such as whales, the flipper refers solely to the forelimbs. In animals with four flippers, such as pinnipeds and sea turtles, one may distinguish fore- and hind-flippers, or pectoral flippers and pelvic flippers.

Episkopi Bay (Greek: Κόλπος Επισκοπής; Turkish: Piskobu Körfezi) is a bay west of the Akrotiri Peninsula on the south-western shore of Cyprus, between Paphos and Akrotiri. On the other side of the Akrotiri Peninsula is Akrotiri Bay. It is famous for its beaches and fish restaurants. Despite the Turkish invasion and ensuing ethnic division of Cyprus in 1974, a number of Turkish Cypriots chose to remain in the area.

Episkopi Bay is a nesting ground for green and loggerhead turtles, both of which are on the IUCN list of endangered species. Episkopi Turtle Watch is a local volunteer group dedicated to the conservation of the turtles and their nesting beaches.

Sea turtles (superfamily Chelonioidea), sometimes called marine turtles, are reptiles of the order Testudines and of the suborder Cryptodira. The seven existing species of sea turtles are the flatback, green, hawksbill, leatherback, loggerhead, Kemp's ridley, and olive ridley. 5 of the seven species are listed as threatened with extinction globally on the IUCN Red List of Threatened Species, the remaining two are not considered to be threatened with extinction. One of which, the flatback turtle, is found only in the waters of Australia, Papua New Guinea, and Indonesia.

Sea turtles can be categorized as hard-shelled (cheloniid) or leathery-shelled (dermochelyid). The only dermochelyid species of sea turtle is the leatherback.

Biscayne National Park is a national park of the United States located south of Miami, Florida, in Miami-Dade County. The park preserves Biscayne Bay and its offshore barrier reefs. The shore of the bay is the location of an extensive mangrove forest. The park covers 172,971 acres (69,998.9 ha; 270.3 sq mi; 700.0 km), of which 9,075 acres (3,673 ha) are on land. It includes Elliott Key, the park's largest island and northernmost of the true Florida Keys, formed from fossilized coral reef. The islands farther north in the park are transitional islands of coral and sand. The offshore portion of the park includes the northernmost region of the Florida Reef, one of the largest coral reefs in the world.

Biscayne National Park protects four distinct ecosystems: part of the Florida mangroves along the shoreline, the shallow waters of Biscayne Bay, the coral limestone keys, and the offshore Florida Reef. The shoreline swamps of the mainland and island margins provide a nursery for larval and juvenile fish, molluscs, and crustaceans. The bay waters harbor immature and adult fish, seagrass beds, sponges, soft corals, and manatees. The keys are covered with tropical vegetation including endangered cacti and palms, and their beaches provide nesting grounds for endangered sea turtles. Offshore reefs and waters harbor more than 200 species of fish, pelagic birds, whales, and hard corals. Sixteen endangered species including Schaus' swallowtail butterflies, smalltooth sawfish, manatees, and green and hawksbill sea turtles may be observed in the park. Biscayne also has a small population of threatened American crocodiles and a few American alligators.

Tromelin Island (/ˌtroʊmlɪn/; French: Île Tromelin, pronounced [il tʁɔmlɛ̃]), once called the Isle of Sand, is a low, flat island in the Indian Ocean about 500 km (310 mi; 270 nmi) north of Réunion and about 450 km (280 mi; 240 nmi) east of Madagascar. Both France and Mauritius claim sovereignty over the islands, and France includes it in the Scattered Islands in the Indian Ocean, the fifth district of the French Southern and Antarctic Lands.

Tromelin has facilities for scientific expeditions and a weather station. It is a nesting site for birds and green sea turtles.

Sea turtle migration is the long-distance movement of sea turtles (superfamily Chelonioidea), comprising the swimming of adults to their breeding beaches, and also the offshore migration of hatchings. Sea turtle hatchings emerge from underground nests and crawl across the beach towards the sea. They then head offshore to the open sea. The feeding and nesting sites of adult sea turtles may be far apart, requiring some to migrate hundreds or even thousands of kilometres.

Several patterns of adult migration have been identified. Some green sea turtles shuttle between nesting sites and coastal foraging areas. The loggerhead sea turtle uses a series of foraging sites. Others such as the leatherback sea turtle and olive ridley sea turtle do not keep to one coastal foraging site, but forage in different areas in the open sea. Although the leatherbacks seem to forage randomly, drifting passively with the currents, they still return to specific sites to breed. The ability of adult sea turtles to travel to precise locations has led biologists to wonder about their navigational mechanisms. Some have suggested that turtles might use the Earth's magnetic field to fix their position. There is evidence for this ability in juvenile green sea turtles.
