Bald Head Island, historically Smith Island, is a village located on the east side of the Cape Fear River in Brunswick County, North Carolina, United States. Compared to the nearby city of Wilmington to the north, the village of Bald Head Island is small and somewhat remote. It is accessible by ferry from the nearby town of Southport and by four-wheel drive vehicle along the beach strand from Fort Fisher to the north. Only government officials are allowed to drive the beach strand route. There are few cars on the island; instead, residents drive modified electric golf carts. Bald Head Island is nationally recognized for its sea turtle nesting activity.
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 sea turtles. All of the seven species listed above, except for the flatback, are present in US waters, and are listed as endangered and/or threatened under the Endangered Species Act. The flatback itself exists 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.
Cheloniidae is a family of typically large marine turtles that are characterised by their common traits such as, having a flat streamlined wide and rounded shell and almost paddle-like flippers for their forelimbs. They are the only sea turtles to have stronger front limbs than back limbs. The six species that make up this family are: the green sea turtle, loggerhead sea turtle, olive ridley sea turtle, hawksbill sea turtle, flatback sea turtle and the Kemp's ridley sea turtle.
The leatherback sea turtle, sometimes called the lute turtle or leathery turtle or simply the luth, is the largest of all living turtles and the heaviest non-crocodilian reptile, reaching lengths of up to 1.8 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.
Hunting Island is a 5,000-acre (20 km2) secluded semitropical barrier island located 15 miles (24 km) east of Beaufort, South Carolina, United States in between Harbor Island and Fripp Island. Since 1935, it has been classified as a state park. It is the most-visited state park facility in South Carolina and is a part of the ACE Basin estuarine reserve area. Known for its natural environment, the island remains one of the few remaining undeveloped Sea Islands in the Lowcountry. The park is known for its 19th century lighthouse which bears its name. The park's beach has been featured in several travel publications and was listed in 2013 as a Top 25 beach in the United States by TripAdvisor.
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 diamondback terrapin or simply terrapin is a species of turtle native to the brackish coastal tidal marshes of the Northeastern and southern United States, and in Bermuda. It belongs to the monotypic genus Malaclemys. It has one of the largest ranges of all turtles in North America, stretching as far south as the Florida Keys and as far north as Cape Cod.
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, not to the color of its carapace, which is olive to black.
The Australian flatback sea turtle is a species of sea turtle in the family Cheloniidae. The species is endemic to the sandy beaches and shallow coastal waters of the Australian continental shelf. This turtle gets its common name from the fact that its shell has a flattened or lower dome than the other sea turtles. It can be olive green to grey with a cream underside. It averages from 76 to 96 cm in carapace length and can weigh from 70 to 90 kg. The hatchlings, when emerging from nests, are larger than other sea turtle hatchlings when they hatch.
Cayo Costa State Park is a state park in the U.S. state of Florida, on Cayo Costa, an island directly south of Boca Grande and just north of North Captiva Island, approximately 12 miles (19 km) west of Cape Coral. The park is accessible only by charter boat, private boat, ferry or helicopter.
ARCHELON, the Sea Turtle Protection Society of Greece was founded in 1983. It aims to protect sea turtles and their habitats in Greece through research, public awareness campaigns, restoring habitats, and through its rescue centre, built in 1994.
Gahirmatha Beach is a beach in Kendrapara district of the Indian state of Odisha. The beach separates the Bhitarkanika Mangroves from the Bay of Bengal and is the world's most important nesting beach for olive ridley sea turtles. The beach is part of Gahirmatha Marine Wildlife Sanctuary, which also includes the adjacent portion of the Bay of Bengal.
Wassaw Island is one of the Sea Islands. It is located on the Atlantic Ocean off the coast of the U.S. state of Georgia and is within the borders of Chatham County. The island and its surrounding marshlands are part of the Wassaw National Wildlife Refuge, which has a total area of 10,053 acres (40.68 km2) of marsh, mudflats, and tidal creeks, including approximately 7 miles (11 km) of undeveloped beaches. The land mass is 76 percent salt marshes and 24 percent beaches, dunes, and maritime forest. The refuge is a part of the Savannah Coastal Refuges Complex.
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.
Sea turtle migration is the long-distance movements of sea turtles notably the long-distance movement of adults to their breeding beaches, but also the offshore migration of hatchings. Sea turtle hatchings emerge from underground nests and crawl across the beach towards the sea. They then maintain an offshore heading until they reach the open sea. The feeding and nesting sites of adult sea turtles are often distantly separated meaning some must migrate hundreds or even thousands of kilometres.
The Turtle Conservancy (TC) is a 501(c)3 organization with a focus on protecting threatened turtles and tortoises and their habitats worldwide working toward improving turtle and tortoise populations in the wild. The TC is a conservation organization protecting tortoises and freshwater turtles with work in five areas: species conservation, protection of wild lands, research science, global awareness and education, and illegal trade prevention.
Ocypode convexa, commonly known as the golden ghost crab, or alternatively the western ghost crab or yellow ghost crab, is a species of ghost crabs endemic to the coast of Western Australia, from Broome to Perth. They are relatively large ghost crabs, with a carapace growing up to 45 mm (1.8 in) long and 52 mm (2.0 in) wide. They are easily recognisable by their golden yellow colouration. Like other ghost crabs they have box-like bodies with unequally sized claws. They also have large eyestalks with the cornea occupying most of the bottom part.
The Gnaraloo Turtle Conservation Program (GTCP) is an environmental organisation based at the Gnaraloo pastoral station and run by the Gnaraloo Wilderness Foundation, a not-for-profit organisation. The aim of the GTCP is to identify, monitor and protect the nesting beaches of loggerhead sea turtles found at two locations on the Gnaraloo coastline. These two rookeries contribute to the South-East Indian Ocean subpopulation of loggerhead turtles, with other major nesting sites for this sub-population at Dirk Hartog island and Exmouth. This is within the southern boundaries of the Ningaloo Coast marine area, a UNESCO World Heritage Site.
The Gnaraloo Feral Animal Control Program (GFACP) operates in conjunction with the Gnaraloo Turtle Conservation Program (GTCP), a non-governmental organization whose aim is to monitor and protect sea turtle nesting beaches along the coast of Gnaraloo. Since its implementation in 2009, the GFACP has worked to reduce the impact of feral predators on sea turtle nests within these rookeries. Gnaraloo is located at the southern end of the Ningaloo Coast, a World Heritage Site. The Ningaloo Reef and surrounding coastline are home to important wildlife, including vulnerable and endangered sea turtle populations.
