The Amazon Reef (also referred to as the Amazonian Reef) is an extensive coral and sponge reef system, located off the coast of French Guiana and northern Brazil. It is one of the largest reef systems in the world known to exist, with scientists estimating its length to be over 600 miles (970 km) long, and covering over 3,600 square miles ...
Locations of coral reefs Boundary for 20 °C isotherms. Most corals live within this boundary. Note the cooler waters caused by upwelling on the southwest coast of Africa and off the coast of Peru. This map shows areas of upwelling in red. Coral reefs are not found in coastal areas where colder and nutrient-rich upwellings occur.
Three-dimensional map of southern Florida showing the Florida Reef in red. The Florida Reef (also known as the Great Florida Reef, Florida reefs, Florida Reef Tract and Florida Keys Reef Tract) is the only living coral barrier reef in the continental United States. [1]
The Great Barrier Reef is the world's largest coral reef system, [1] [2] composed of over 2,900 individual reefs [3] and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi).
While it covers only 1.6% of the planet's oceanic area, the region has 76% of all known coral species in the world. As a habitat for 52% of Indo-Pacific reef fishes and 37% of the world's reef fishes, it contains the greatest diversity of coral reef fishes in the world [17] More than 3,000 species of bony fish are distributed over more than 90% of the Coral Triangle.
On January 19, 2021, NOAA issued the Final Instruction for expansion of Flower Garden Banks National Marine Sanctuary. This action protects 14 additional reefs and banks, slightly adjusts the boundaries of the sanctuary's original three banks and expands the sanctuary from 56 square miles (145 km 2) to a total of 160 square miles (415 km 2).
Aerial view of Ningaloo Reef in Western Australia, the largest fringing coral reef in the world and a UNESCO World Heritage Site. Fringing reefs are located near shore in the tropics in many areas and are the most common reef type. Coral reefs are found in the tropics in which the water is between 18 and 30 °C (64 and 86 °F).

The reef has a number of colonies [citation needed] of hard coral atop rock outcroppings that run parallel to the coast, [5] occurring in progressively deeper water offshore. After organizing by local community groups, [ 6 ] the area was designated a national park in 1995, a UNESCO World Heritage Site in 2005, and a Ramsar Wetland of ...
