Pickles Reef
Pickles Reef is a small coral reef located within the Florida Keys National Marine Sanctuary. It lies to the southeast of Key Largo, to the south the Key Largo Existing Management Area and John Pennekamp Coral Reef State Park. Unlike many reefs within the Sanctuary, this reef is not within a Sanctuary Preservation Area (SPA). The reef gets its name from the Pickle Barrel wreck. Another small reef called Snapper Ledge is nearby. Shipwreck Various types of debris are scattered across the reef, including a number of barrel-shaped concrete objects. Local legend was that the concrete objects had been barrels of concrete on a ship or barge that had wrecked on the reef during the Civil War, but an analysis performed in 2008 showed that the concrete was a type of Portland cement produced between 1890 and 1923. Archaeologists have found evidence of an iron- or steel-hulled vessel with two masts that wrecked on the reef, but have not identified the ship. It is not clear how much ...

Haemulidae
Haemulidae is a family of fishes in the order Perciformes known commonly as grunts. It is made up of the two subfamilies Haemulinae (grunters) and Plectorhynchinae (sweetlips), which in turn contain about 133 species in 19 genera. These fish are found in tropical fresh, brackish, and salt waters around the world. They are bottom-feeding predators, and named for the ability of Haemulinae to produce sound by grinding their teeth. They also engage in mutualistic relationship with cleaner gobies of genus ''Elacatinus'', allowing them to feed on ectoparasites on their bodies.

Snapper Ledge (reef)
Snapper Ledge is a small coral reef located within the Florida Keys National Marine Sanctuary. It lies to the southeast of Key Largo, to the south the Key Largo Existing Management Area and John Pennekamp Coral Reef State Park. Unlike many reefs within the Sanctuary, this reef is not within a Sanctuary Preservation Area (SPA). It is near Pickles Reef. Since 2009, the Coral Restoration Foundation has used Snapper Ledge as a nursery site to grow Elkhorn coral (''Acropora palmata'').

Brain Coral
Brain coral is a common name given to various corals in the families Mussidae and Merulinidae, so called due to their generally spheroid shape and grooved surface which resembles a brain. Each head of coral is formed by a colony of genetically identical polyps which secrete a hard skeleton of calcium carbonate; this makes them important coral reef builders like other stony corals in the order Scleractinia. Brain corals are found in shallow warm water coral reefs in all the world's oceans. They are part of the phylum Cnidaria, in a class called Anthozoa or "flower animals". The lifespan of the largest brain corals is 900 years. Colonies can grow as large as 1.8 m (6 ft) or more in height. Brain corals extend their tentacles to catch food at night. During the day, they use their tentacles for protection by wrapping them over the grooves on their surface. The surface is hard and offers good protection against fish or hurricanes. Branching corals, such as staghorn cor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stoplight Parrotfish
The stoplight parrotfish (''Sparisoma viride'') is a species of marine ray-finned fish, a parrotfish from the family Scaridae, inhabiting coral reefs in Florida, Caribbean Sea, Gulf of Mexico, Bermuda and as far south as Brazil. It mainly feeds on algae by scraping and excavating it with its teeth. Like most of its relatives, it is able to change sex. The common name, stoplight, comes from the marked yellow spot near the pectoral fin, which is clearly visible only in specimens in the terminal phase. Sex Change & Coloring The stoplight parrotfish is a protogynous hermaphrodite that shows full sexual dichromatism, meaning that it changes its sex from female to male during its lifespan, and its color changes with its sex change. The sex change is most likely due to the control of hormones, in particular, 11-ketetestosterone (11-KT). The timing of the sex change can vary depending on population density, growth, and mortality rates. Early sex changes may occur if sexually active ...

Spotted Trunkfish
The spotted trunkfish (''Lactophrys bicaudalis'') is a member of the family Ostraciidae. It can be found in reefs throughout the Caribbean, as well as the south western Atlantic Ocean. The species gets its name from the black spots it has covered over its whitish or yellow-golden body. In many Caribbean countries, it is colloquially known as box-fish or cow-fish, and shell-fish in the Eastern Caribbean. Description Members of this family are known as boxfishes because they have a hard outer covering consisting of hexagonal plate-like scales fused together into a solid, triangular or box-like carapace. The eyes, snout, fins and tail protrude from this. The spotted trunkfish is basically white or yellowish with a regular pattern of numerous black spots on the body and tailfin. Just behind the eye, adult fish have a diagonal row of three white spots where black ones would have been expected. The snout is plain white, there are no spines above the eye, and there are a pair of sharp s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portland Cement
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of gypsum. Several types of portland cement are available. The most common, called ordinary portland cement (OPC), is grey, but white Portland cement is also available. Its name is derived from its resemblance to Portland stone which was quarried on the Isle of Portland in Dorset, England. It was named by Joseph Aspdin who obtained a patent for it in 1824. His son William Aspdin is regarded as the inventor of "modern" portland cement due to his developments in the 1840s. The low cost and widespread availability of the limestone, sh ...

American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shipwreck
A shipwreck is the wreckage of a ship that is located either beached on land or sunken to the bottom of a body of water. Shipwrecking may be intentional or unintentional. Angela Croome reported in January 1999 that there were approximately three million shipwrecks worldwide (an estimate rapidly endorsed by UNESCO and other organizations). When a ship's crew has died or abandoned the ship, and the ship has remained adrift but unsunk, they are instead referred to as ghost ships. Types Historic wrecks are attractive to maritime archaeologists because they preserve historical information: for example, studying the wreck of revealed information about seafaring, warfare, and life in the 16th century. Military wrecks, caused by a skirmish at sea, are studied to find details about the historic event; they reveal much about the battle that occurred. Discoveries of treasure ships, often from the period of European colonisation, which sank in remote locations leaving few livi ...

Sergeant Major (fish)
The sergeant major or píntano (''Abudefduf saxatilis'') is a species of damselfish. It grows to a maximum length of about . Distribution and habitat ''Abudefduf saxatilis'' is found in the Atlantic Ocean. Populations in the western part of the Atlantic Ocean are found from the north eastern coast of the United States south to the Gulf of Mexico, the Bahamas, islands around the Caribbean Sea, the eastern coast of Central and South America all the way to Uruguay. In the eastern Atlantic Ocean, they are found from Portugal, Azores, the Canary Islands, Cape Verde, and western Africa. Its distribution remains unclear in the Mediterranean Sea due to possible confusion with Abudefduf vaigiensis and Abudefduf troschelii.Atlas of Exotic Fishes in the Mediterranean Sea (Abudefduf saxatilis). 2nd Edition. 2021. 366p.

John Pennekamp Coral Reef State Park
John Pennekamp Coral Reef State Park is a Florida State Park located on Key Largo in Florida. It includes approximately 70 nautical square miles (240 km²) of adjacent Atlantic Ocean waters. The park is approximately 25 miles in length and extends 3 miles into the Atlantic Ocean. It was the first underwater park in the United States. The park was added to the National Register of Historic Places on April 14, 1972. The primary attractions of the park are the coral reefs (such as Molasses Reef) and their associated marine life. In Fiscal Year 2004 the park had more than a million visitors, making it the most popular park in the Florida State Parks system. The Florida Keys and the Flower Garden Banks in the Gulf of Mexico off the Texas coast are the only living coral reef formations in the continental United States. History Plans to designate the reefs off Key Largo for a park started in the 1930s. The state-sanctioned Everglades National Park Commission proposed a nati ...

Key Largo
Key Largo ( es, Cayo Largo) is an island in the upper Florida Keys archipelago and is the largest section of the keys, at long. It is one of the northernmost of the Florida Keys in Monroe County, and the northernmost of the keys connected by U.S. Highway 1 (the Overseas Highway). Three census-designated places are on the island of Key Largo: North Key Largo, near the Card Sound Bridge, Key Largo, eight to nine miles from the southern end of the island, and Tavernier, at the southern end of the island. As of 2010, the three places have a combined population of 13,850. None of Key Largo is an incorporated municipality, so it is governed at the local level by Monroe County. Key Largo is connected to the mainland in Miami-Dade County by two routes. The first route is the Overseas Highway, the southernmost portion of U.S. Highway 1, which enters Key Largo at Jewfish Creek near the middle of the island and turns southwest. The second route is Card Sound Road, which connects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
