The loggerhead sea turtle is found in the Atlantic, Pacific, and Indian oceans as well as the Mediterranean Sea. Is is omnivorous, feeding mainly on bottom dwelling invertebrates. Its large and powerful jaws serve as an effective tool for dismantling its prey.
The loggerhead sea turtle is the world's largest hard-shelled turtle. Adult loggerheads have an average weight range of 80 to 200 kg and a length range of 70 to 95 cm . The maximum reported weight is 545 kilograms and the maximum carapace length is 213 cm. The head and carapace (upper shell) range from a yellow-orange to a reddish-brown, while the plastron (underside) is typically pale yellow. Like the Hawkbill sea turtle, it has two claws on each flipper.

Tortue franche - Green Sea Turtle - Chelonia mydas
Scale 1:15 - 1:29

Tortue d'Agassiz - Black ( or Eastern Pacific green) Sea Turtle - Chelonia agassizii
Scale 1:15 - 1:28

Some authors do not recognise Chelonia agassizii as a species separate from Chelonia mydas but as a subspecies, Chelonia mydas agassizii.
This turtle is found along the West coast of America, from California to southern Peru. It is essentially a herbivorous species, but hatchlings and juveniles feed on pelagic animals before moving inshore. Migrating adults feed on a wide range of invertebrates including molluscs, sponges, jellyfish, annelids and tunicates. Most graze on algae, sea grasses and mangrove shoots.
Smaller than the Green turtle, the Black sea turtle have an average length of 65 to 95cm.

Tortue luth - Leatherback Sea Turtle - Dermochelys coriacea
Scale 1:15 - 1:25

The leatherback turtle, sometimes called the lute turtle, is the largest of all living turtles (as well as the largest extant sea turtle) and is the fourth largest modern reptile behind three crocodilians. It can easily be differentiated from other modern sea turtles by its lack of a bony shell. Instead, its carapace is covered by skin and oily flesh. Leatherback turtles have the most hydrodynamic body design of any sea turtle, with a large, teardrop-shaped body. A large pair of front flippers power the turtles through the water. Claws are absent from both pairs of flippers. Instead of teeth, the leatherback turtle has points on the tomium of its upper lip, with backwards spines in its throat to help it swallow food.
Of all the extant sea turtle species, it has the widest distribution, reaching as far north as Alaska and Norway and as far south as the Cape of Good Hope in Africa and the southernmost tip of New Zealand.[6] The leatherback is found in all tropical and subtropical oceans, and its range extends well into the Arctic Circle.
Adults average 1–1.75 m in carapace length, 1.83–2.2 m in total length and weigh 250 to 700 kg. In the Caribbean, the mean size of adults was reported at 384 kg  in weight and 1.55 m  along the curve of the carapace. On a beach on the west coast of Wales, the largest ever found, however, was over 3 m from head to tail, including a carapace length of over 2.2 m and weighed 916 kilograms.

Tortue imbriquée - Hawksbill Sea Turtle - Eretmochelys imbricata
Scale 1:15 - 1:25

The hawksbill sea turtle is a critically endangered sea turtle. The species has a worldwide distribution, with Atlantic and Pacific subspecies.
The hawksbill's appearance is similar to that of other marine turtles. It has a generally flattened body shape, a protective carapace, and flipper-like arms, adapted for swimming in the open ocean. It is easily distinguished from other sea turtles by its sharp, curving beak with prominent tomium, and the saw-like appearance of its shell margins. The hawksbill's arms have two visible claws on each flipper.
Hawksbill shells slightly change colors, depending on water temperature. While this turtle lives part of its life in the open ocean, it spends more time in shallow lagoons and coral reefs.
Adult hawksbill sea turtles have been known to grow up to 1 metre (3 ft) in length, weighing around 80 kilograms (180 lb) on average. The heaviest hawksbill ever captured was measured to be 127 kilograms (280 lb).[4] The turtle's shell, or carapace, has an amber background patterned with an irregular combination of light and dark streaks, with predominantly black and mottled brown colors radiating to the sides.
Adult hawksbill sea turtles have been known to grow up to 1m in length, weighing around 80 kilograms on average. The heaviest hawksbill ever captured was measured to be 127 kilograms.

Tortue bâtarde - Kemp's Ridley Sea Turtle - Lepidochelys kempii
Scale 1:15 - 1:23

Kemp's ridley sea turtle is the rarest sea turtle and is critically endangered. It is a small sea turtle species, reaching maturity at 60–90 centimetres long and averaging only 45 kilograms. Kemp's ridley sea turtles generally prefer warm waters but inhabit waters as far north as New Jersey, They migrate to the Gulf of Mexico, and Florida where they often inhabit the waters off Louisiana. Their range includes the Atlantic Ocean and the Gulf of Mexico. Almost all females return each year to a single beach—Rancho Nuevo in the Mexican state of Tamaulipas—to lay eggs. Some travel as far away as the coast of Ireland.
The Kemp's ridley turtle feeds on molluscs, crustaceans, jellyfish, algae or seaweed, and sea urchins.

Tortue olivâtre - Olive ridley sea turtle - Lepidochelys olivacea
Scale 1:15 - 1:20

The olive ridley is a small extant sea turtle, with an adult carapace length averaging 60 to 70 cm The heart-shaped carapace is characterized by four pairs of pore-bearing inframarginal scutes on the bridge, two pairs of prefrontals, and up to nine lateral scutes per side.
Olive ridleys are unique in that they can have a variable and asymmetrical lateral scute count ranging from five to nine plates on each side, with six to eight being most commonly observed;
The olive ridley turtle has a circumtropical distribution living in tropical and warm waters of the Pacific and Indian Oceans from India, Arabia, Japan, and Micronesia south to southern Africa, Australia, and New Zealand. In the Atlantic Ocean, it has been observed off the western coast of Africa and the coasts of northern Brazil to Venezuela. Additionally, there have been records of the olive ridley in the Caribbean Sea as far north as Puerto Rico. It is also found in the eastern Pacific Ocean from the Galapagos Islands and Chile north to the Gulf of California, and along the Pacific coast to at least Oregon.
The olive ridley sea turtles are considered the most abundant, yet globally they have declined by more than 30% from historic levels. These turtles are considered endangered because of their few remaining nesting sites in the world.
The olive ridley is predominantly carnivorous, especially in immature stages of the life cycle. Animal prey consists of protochordates or invertebrates, which can be caught in shallow marine waters or estuarine habitats. Common prey items include jellyfish, tunicates, sea urchins, bryozoans, bivalves, snails, shrimp, crabs, rock lobsters, and sipunculid worms.

Tortue à dos plat - Flatback sea turtle - Natator depressus
Scale 1:20 - 1:32

Flatback turtles are usually found in bays, shallow, grassy waters, coral reefs, estuaries and lagoons on the northern coast of Australia and off the coast of Papua New Guinea.
The species may feed off Indonesia and Papua New Guinea, but it nests only the top half of Australia, from Exmouth in Western Australia to Mon Repos Conservation Park in Queensland. The most significant breeding site is Crab Island in the western Torres Strait. Breeding may also occur on the islands of the southern Great Barrier Reef, and on mainland beaches and offshore islands north of Gladstone.
The Flatback turtle eats a variety of organisms such as seagrass, marine invertebrates including mollusks, jellyfish and shrimp and also fishes. It also consumes of soft coral, sea cucumbers and other soft-bodied creatures
The carapace of the adult is on average 90 to 125 cm long. It is low domed, the edge is upturned and has four pairs of costal scales—fewer than other marine turtles. The upper parts are an olive-grey, while it is more pale ventrally. A single pair of scales are located at the front of the head, which also distinguish this species.
