Orbicella franksi seems to be more resistant to coral diseases than some members of its genus, but is still susceptible to coral plague, yellow-band disease, black band disease and coral bleaching. [1] The major threats it faces include climate change, ocean acidification and destruction of its reef habitat.
Black corals occur throughout all the oceans from the surface down to the deep-sea, though nearly 75% of species are only found at depths below 50 m (164 ft). The sole oceanic area in which black corals have not been found are brackish waters , though they can inhabit areas with decreased salinity . [ 15 ]
Proposals for the creation of a marine protected area (MPA) in India to combat this trend have existed as early as 2003. [3] Proposals for the Aggatti Conservation Reserve were first moved in 2008, and in 2020, three MPAs were created in Lakshadweep: the Dr. K.K. Mohammed Koya Sea Cucumber Conservation Reserve, the Attakoya Thangal Marine Reserve 344 km 2 (133 sq mi), and the PM Sayeed Marine ...
Aipysurus duboisii, also known commonly as Dubois' sea snake and the reef shallows sea snake, is a species of extremely venomous snake in the subfamily Hydrophiinae of the family Elapidae. Its geographic range includes Papua New Guinea , New Caledonia and the northern, eastern and western coastal areas of Australia , that is the Coral Sea ...
The laced moray is widespread throughout the Indo-West Pacific area from eastern coast of Africa, Red Sea included, to Papua New Guinea and from southern Japan to the Great Barrier Reef. [5] [6] It lives on the outer slopes of coral reefs. During the day, it sits sheltered in crevices between 1 and 45 meters (3 and 150 feet) deep. [7]
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
The giant moray is carnivorous and nocturnal, hunting its prey within the reef. It is known to engage in cooperative hunting with the roving coral grouper (Plectropomus pessuliferus). [7] These two fish species are complementary hunters: While the eel hunts in the reef, it may scare prey up and out of the reef, leaving them to be eaten by the ...
The blacktip reef shark has also been known to become aggressive in the presence of bait, and may pose a threat while attempting to steal the catches of spear fishers. [3] The blacktip reef shark is a normal catch of coastal fisheries, such as those operating off Thailand and India, but is not targeted or considered commercially important. [9]
