Sea turtles, 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. Six of the seven sea turtle species, all but the flatback, are present in U.S. waters, and are listed as endangered and/or threatened under the Endangered Species Act. All but the flatback turtle are listed as threatened with extinction globally on the IUCN Red List of Threatened Species. The flatback turtle is found only in the waters of Australia, Papua New Guinea, and Indonesia.
The leatherback sea turtle, sometimes called the lute turtle, leathery turtle or simply the luth, is the largest of all living turtles and the heaviest non-crocodilian reptile, reaching lengths of up to 2.7 metres and weights of 500 kilograms (1,100 lb). It is the only living species in the genus Dermochelys and family Dermochelyidae. It can easily be differentiated from other modern sea turtles by its lack of a bony shell; instead, its carapace is covered by oily flesh and flexible, leather-like skin, for which it is named. Leatherback turtles have a global range, although there are multiple distinct subpopulations. The species as a whole is considered vulnerable, and some of its subpopulations are critically endangered.
The olive ridley sea turtle, also known commonly as the Pacific ridley sea turtle, is a species of turtle in the family Cheloniidae. The species is the second-smallest and most abundant of all sea turtles found in the world. L. olivacea is found in warm and tropical waters, primarily in the Pacific and Indian Oceans, but also in the warm waters of the Atlantic Ocean.
The loggerhead sea turtle is a species of oceanic turtle distributed throughout the world. It is a marine reptile, belonging to the family Cheloniidae. The average loggerhead measures around 90 cm (35 in) in carapace length when fully grown. The adult loggerhead sea turtle weighs approximately 135 kg (298 lb), with the largest specimens weighing in at more than 450 kg (1,000 lb). The skin ranges from yellow to brown in color, and the shell is typically reddish brown. No external differences in sex are seen until the turtle becomes an adult, the most obvious difference being the adult males have thicker tails and shorter plastrons than the females.
The green sea turtle, also known as the green turtle, black (sea) turtle or Pacific green turtle, is a species of large sea turtle of the family Cheloniidae. It is the only species in the genus Chelonia. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name refers to the usually green fat found beneath its carapace, due to its diet strictly being seagrass, not to the color of its carapace, which is olive to black.

Boca de Cielo is a small fishing town and beach in the municipality of Tonalá, Chiapas, Mexico. It and Puerto Arista, fifteen km away, are the two best known beaches on the Chiapas coast. Boca de Cielo is part of Chiapas’ Istmus-Costa Region on the north coast. it is one of many beaches in the region that stretch uninterrupted by anything except estuaries and lagoons formed by the small rivers that run from the nearby Sierra Madre de Chiapas mountains to the Pacific Ocean. The climate is semi moist with rain mostly in the summer and an average annual temperature of 27C, with weather is hottest in the spring and summer. The area around Boca del Cielo is filled with pastures for cattle as this is the main economic activity of the northern coast region.
The hawksbill sea turtle is a critically endangered sea turtle belonging to the family Cheloniidae. It is the only extant species in the genus Eretmochelys. The species has a global distribution that is largely limited to tropical and subtropical marine and estuary ecosystems.
The Penghu National Scenic Area is one of the National Scenic Areas of the Republic of China (Taiwan), and covers most, but not all of the islands and islets that form Penghu County. These islands have a total of 320 kilometers of shoreline. A National Scenic Area is not a National Park. National Scenic Areas fall within the control of the Tourism Bureau of the Ministry of Transportation and Communications of the Republic of China, while national parks fall within the jurisdiction of the Ministry of Interior of the Republic of China. The philosophies that govern the development of the two types of areas differ. For a national park the emphasis is on the preservation of natural and cultural resources, and development for human utilization is definitely a secondary priority. For a national scenic area, the priorities are more balanced between preservation and tourism utilization. This has led to conflicts between preservationists and those more favorable to the development of the area. The National Park Law of the Republic of China only applies to the latter areas. Studies about the project were first debated since the beginning of 1990 and, after a year of evaluations carried out by the Tourism Bureau of the Ministry of Transportation and Communications of the Republic of China, it was officially created in February 1991, when the Penghu office was finally established. The aim of the project was to "efficiently utilize the local resources and help Penghu's economic growth", while building vacation spots on the coast of Taiwan's only island county to attract both Taiwanese nationals and foreigners, making of Penghu an "International tourism vacation center". It is a well known scenic area for its sandy beaches. The tourist season in Penghu starts in April and peaks from June through August. The Scenic Area attracts thousands of weekenders with its brisk sea breezes and scenery. But when the autumn gales begin to blow in October, the archipelago becomes deserted until April, when warmer weather seems to thaw the local tourism industry. In addition to its rich oceanic resources, Penghu offers fantastic sights of basalt column formations. The scenic area lures more than 200 species of migratory birds, making it an important spot for Asia's birdwatchers. It was not always like this: for much of the second half of the past century, the Government of the Republic of China saw the islands in mainly political and military terms, as a naval base: "Penghu was regarded as a military base until the early 1990s. As a result, the central government never wanted to develop the islands, which resulted in Penghu's shortages of water and electricity and, of course, a lot of five-star hotels".
Kadmat Island, also known as Cardamom Island, is a coral island belonging to the Amindivi subgroup of islands of the Lakshadweep archipelago in India.

Threats to sea turtles are numerous and have caused many sea turtle species to be endangered. Of the seven extant species of sea turtles, six in the family Cheloniidae and one in the family Dermochelyidae, all are listed on the IUCN Red List of Endangered Species. The list classifies six species of sea turtle as "threatened", two of them as "critically endangered", one as "endangered" and three as "vulnerable". The flatback sea turtle is classified as "data deficient" which means that there is insufficient information available for a proper assessment of conservation status. Although sea turtles usually lay around one hundred eggs at a time, on average only one of the eggs from the nest will survive to adulthood. While many of the things that endanger these hatchlings are natural, such as predators including sharks, raccoons, foxes, and seagulls, many new threats to the sea turtle species are anthropogenic.
