A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. [1] Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and ...
They provide habitats and food for a diversity of marine life comparable to coral reefs. This includes invertebrates like shrimp and crabs, cod and flatfish, marine mammals and birds. They provide refuges for endangered species such as seahorses, turtles, and dugongs. They function as nursery habitats for shrimps, scallops and many commercial ...
Coral reefs are one of the most well-known marine ecosystems in the world, with the largest being the Great Barrier Reef. These reefs are composed of large coral colonies of a variety of species living together. The corals from multiple symbiotic relationships with the organisms around them. [21] Coral reefs are being heavily affected by global ...
SMEs are characterized by carbonate reefs, which support many species. Estimates suggest that coral reefs alone may host between 1-9 million species. The three main types of reef formations are: [8] Fringing Reefs: attached to the shore; Barrier Reefs: separated from the mainland by a lagoon; Atoll Reefs: ring-shaped reefs surrounding a lagoon
Other common species of hard coral found on the Florida Reef include Ivory Bush Coral (Oculina diffusa), which is the dominant coral in the patch reefs along the Florida coast north of the Florida Keys, staghorn coral (Acropora cervicornis), lettuce coral (Agaricia agaricites), grooved brain coral (Diploria labyrinthiformis), boulder star coral ...
It includes the Florida Reef, the only barrier coral reef in North America [1] and the third-largest coral barrier reef in the world. It also has extensive mangrove forest and seagrass fields. The Florida Keys National Marine Sanctuary, designated on December 28, 1990, [2] was the ninth national marine sanctuary to be established.
Pavona decussata, sometimes known as leaf coral, is a species of colonial stony coral in the family Agariciidae. It is found in shallow water in various reef habitats, particularly on gently sloping surfaces, in tropical parts of the western and central Indo-Pacific region.
This association has been observed in species that inhabit coral reef habitats. Eusocial behavior has been discovered in the genus Synalpheus. The species Synalpheus regalis lives inside sponges in colonies that can number over 300. [18] All of them are the offspring of a single large female, the queen, and possibly a single male.
