Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...

Lucayan Archipelago
The Lucayan Archipelago, also known as the Bahamian Archipelago, is an island group comprising the Commonwealth of The Bahamas and the British Overseas Territory of the Turks and Caicos Islands. The archipelago is in the western North Atlantic Ocean, north of Cuba and the other Antillean Islands, and east and south-east of Florida. William Keegan writes: "Modern political considerations aside, the islands form a single archipelago with common geological, ecological, and cultural roots." Though it is generally considered part of the Caribbean region, the Lucayan Archipelago is not geographically located within the Caribbean Sea. Countries and territories * The Bahamas * Turks and Caicos Islands (United Kingdom) The Mouchoir Bank, the Silver Bank, and the Navidad Bank are a submerged continuation of the archipelago, to the southeast of the Turks and Caicos Islands.

Islet
An islet ( ) is generally a small island. Definitions vary, and are not precise, but some suggest that an islet is a very small, often unnamed, island with little or no vegetation to support human habitation. It may be made of rock, sand and/or hard coral; may be permanent or tidal (i.e. surfaced reef or seamount); and may exist in the sea, lakes, rivers or any other sizeable bodies of water. Definition As suggested by its origin ''islette'', an Old French diminutive of "isle", use of the term implies small size, but little attention is given to drawing an upper limit on its applicability. The World Landforms website says, "An islet landform is generally considered to be a rock or small island that has little vegetation and cannot sustain human habitation", and further that size may vary from a few square feet to several square miles, with no specific rule pertaining to size. Other terms * Ait (/eɪt/, like eight) or eyot (/aɪ(ə)t, eɪt/), a small island. It is espe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Above Sea Level
Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods. Climate change and other forces can cause sea levels and elevations to vary over time. Uses Elevation or altitude above sea level is a standard measurement for: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Mining infrastructure, particularly underground. * Flying objects such as airplanes or helicopters below a Transition Altitude defined by local regulations. Units and abbreviations Elevation or altitude is generally expressed as "metres above mean sea level" in the metric system, or " feet above mean sea level" in United States customary and imperial units.

Conception Island National Park
The Conception Island National Park is a protected area in the Bahamas. The island lies between Cat Island to the north and Rum Cay to the south. The vegetation consists of mangrove communities, with typical strand vegetation, and the island is visited by green turtles, sea birds and migrating birds. The park The park has a land area of and a maximum altitude of . It is administered by the Bahamas National Trust. Washington Irving identified Conception Island as the site of one of Christopher Columbus' landfalls during his 1492 voyage, but this early theory was not supported by other historians and writers (either at the time or subsequently), who identified different claimant islands as the site of Columbus's landfall. Wilcomb E. Washburn, "Landfall Controversy" in ''The Christopher Columbus Encyclopedia'', Vol. 1 (ed. Silvio A. Bedin: Simon & Schuster, 1992).

Boidae
The Boidae, commonly known as boas or boids, are a family of nonvenomous snakes primarily found in the Americas, as well as Africa, Europe, Asia, and some Pacific islands. Boas include some of the world's largest snakes, with the green anaconda of South America being the heaviest and second-longest snake known; in general, adults are medium to large in size, with females usually larger than the males. Six subfamilies comprising 14-15 genera and 54-67 species are currently recognized. Description Like the pythons, boas have elongated supratemporal bones. The quadrate bones are also elongated, but not as much, while both are capable of moving freely so when they swing sideways to their maximum extent, the distance between the hinges of the lower jaw is greatly increased.Parker, H.W.; Grandison, A.G.C. 1977.

Conception Bank Silver Boa
The Conception Bank silver boa (''Chilabothrus argentum''), also known as the Conception Bank boa or silver boa, is a species of boa described in May 2016 by a team of researchers from Harvard University led by Dr. R. Graham Reynolds. It is only known from the Conception Island Bank in the Bahamas. It is the first known discovery of a West Indian boa species in 73 years. It is named for its unique silver color and the fact that the first specimen was found in a silver palm. It is the most endangered boa in the world, with fewer than 150 individuals in an area of just 5 hectares. Description Conception Bank silver boas have silver to tan dorsal background coloration, with or without scattered dark brown scales. Ventral scales are pure cream-white. Juveniles undergo ontogenetic color change, from a light brownish-orange coloration with heavy patterning as neonates to the adult coloration around 400-500 mm snout-vent length. They measure in snout–vent length and weigh . Tail le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...
