The reefs in this area are narrow fringing reefs located 150 to 300 m. from the shore of the islands and patch reefs rising up from depths of 2 to 9 m. and extending up to 2 km. long and 50 m. wide. Large areas of these reefs are in generally poor condition due to destructive human activities of the 150,000 persons living along the coast ...
In May 2019, The National Centre for Coastal Research, an institute under the Ministry of Earth Sciences of India, which has a field research station in the Gulf of Mannar region, found an alarming pattern of bleaching in the reefs in Mandapam, Kilakarai and Palk Bay. Researchers observed a pattern of bleaching in corals when the temperatures ...
Coral reefs deliver ecosystem services for tourism, fisheries and shoreline protection. The annual global economic value of coral reefs has been estimated at anywhere from US$30–375 billion (1997 and 2003 estimates) [14] [15] to US$2.7 trillion (a 2020 estimate) [16] to US$9.9 trillion (a 2014 estimate).

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 ...
The park is home to more than 40 species of sponges, 40 species of hard coral and 10 species of soft coral. [2] A sea slug on the sea floor rock. As the sea recedes, the sea creatures are exposed to the harsh sunlight before they retreat to deeper waters or take cover under rocks. The western reef heron (dark morphed) on the prowl.

These coral reefs are thousands of years old with the youngest being from 5,240 years old at Salaya although these coral ...
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.
It is a coral reef. The depth may vary; at some points, the water is 23 metres (75 ft) deep, and at other points, the seafloor can be 400 metres (1,300 ft) below sea level. The bottom is composed of sand, shells, and coral. The bank is steep-to on all sides, with great depths surrounding it. [2]
