Corals are colonial marine invertebrates within the subphylum Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.
Montastraea is a genus of colonial stony coral found in the Caribbean seas. It is the only genus in the monotypic family Montastraeidae and contains a single species, Montastraea cavernosa, known as great star coral. It forms into massive boulders and sometimes develops into plates. Its polyps are the size of a human thumb and fully extend at night.
Saint Martin Island is a small island in the northeastern part of the Bay of Bengal, about 9 km south of the tip of the Cox's Bazar-Teknaf peninsula, and forming the southernmost part of Bangladesh. There is a small adjoining island that is separated at high tide, called Chera Dip. It is about 8 kilometres west of the northwest coast of Myanmar, at the mouth of the Naf River.
The giant grouper (Epinephelus lanceolatus), also known as the Queensland groper (grouper), brindle grouper or mottled-brown sea bass, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It has a wide Indo-Pacific distribution and is one of the largest extant species of bony fish.
Alcyonacea are an order of sessile colonial cnidarians that are found throughout the oceans of the world, especially in the deep sea, polar waters, tropics and subtropics. Whilst not in a strict taxonomic sense, Alcyonacea are commonly known as soft corals. The term "soft coral" generally applies to organisms in the two orders Pennatulacea and Alcyonacea with their polyps embedded within a fleshy mass of coenenchymal tissue. Consequently, the term "gorgonian coral" is commonly handed to multiple species in the order Alcyonacea that produce a mineralized skeletal axis composed of calcite and the proteinaceous material gorgonin only and corresponds to only one of several families within the formally accepted taxon Gorgoniidae (Scleractinia). These can be found in order Malacalcyonacea (taxonomic synonyms of include : Alcyoniina, Holaxonia, Protoalcyonaria, Scleraxonia, and Stolonifera. They are sessile colonial cnidarians that are found throughout the oceans of the world, especially in the deep sea, polar waters, tropics and subtropics. Common names for subsets of this order are sea fans and sea whips; others are similar to the sea pens of related order Pennatulacea. Individual tiny polyps form colonies that are normally erect, flattened, branching, and reminiscent of a fan. Others may be whiplike, bushy, or even encrusting. A colony can be several feet high and across, but only a few inches thick. They may be brightly coloured, often purple, red, or yellow. Photosynthetic gorgonians can be successfully kept in captive aquaria.
Phyllodesmium longicirrum, common name the solar-powered phyllodesmium, is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusc in the family Facelinidae.
Ovula ovum, common name the common egg cowrie, is a species of sea snail, a marine gastropod mollusk in the family Ovulidae, the ovulids, cowry allies or false cowries.
Copper alloys are important netting materials in aquaculture. Various other materials including nylon, polyester, polypropylene, polyethylene, plastic-coated welded wire, rubber, patented twine products, and galvanized steel are also used for netting in aquaculture fish enclosures around the world. All of these materials are selected for a variety of reasons, including design feasibility, material strength, cost, and corrosion resistance.
The areolate grouper, also known as the yellowspotted rockcod, areolate rockcod, green-spotted rock-cod, squaretail grouper or squaretail rock-cod, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It inhabits coral reefs in the Indo-Pacific region. They are produced through aquaculture and commercially fished. They currently face no threats to their survival.
Alcyoniidae is a family of leathery or soft corals in the phylum Cnidaria.
Sea sponge aquaculture is the process of farming sea sponges under controlled conditions. It has been conducted in the world's oceans for centuries using a number of aquaculture techniques. There are many factors such as light, salinity, pH, dissolved oxygen and the accumulation of waste products that influence the growth rate of sponges. The benefits of sea sponge aquaculture are realised as a result of its ease of establishment, minimum infrastructure requirements and the potential to be used as a source of income for populations living in developing countries. Sea sponges are produced on a commercial scale to be used as bath sponges or to extract biologically active compounds which are found in certain sponge species. Techniques such as the rope and mesh bag method are used to culture sponges independently or within an integrated multi-trophic aquaculture system setting. One of the only true sustainable sea sponges cultivated in the world occur in the region of Micronesia, with a number of growing and production methods used to ensure and maintain the continued sustainability of these farmed species.
Coral aquaculture, also known as coral farming or coral gardening, is the cultivation of corals for commercial purposes or coral reef restoration. Aquaculture is showing promise as a tool for restoring coral reefs, which are dying off around the world. The process protects young corals while they are most at risk of dying. Small corals are propagated in nurseries and then replanted on the reef.
Litophyton arboreum, also known as broccoli coral, is a common soft coral (octocoral) found from the Red Sea to the Western Pacific. It grows up to 80 cm, usually on seaward reef slopes or hard bottoms. The color of L. arboreum varies from pale olive-green to yellow or grey. L. arboreum are anthozoans in the order Alcyonacea in the family Nephtheidae. The L. arboreum was originally classified in 1775 by Peter Forsskål, a Swedish Linnaean naturalist. As of 2016, the entire genus Litophyton was reclassified using phylogenetic data, in contrast to its original morphological classification.
Callyspongia crassa, commonly known as prickly tube-sponge, is a species of sponge found from the Red Sea to the Seychelles. Its wide flexible brown tube with exterior protuberances can appear as a single tube or as clusters of tubes and can reach up to 50 centimeters in size. Like many other sea sponges, it is primarily used for marine drugs as they have many bioactive components and properties. They also play an important role in marine reef and benthic communities, as they constantly filter water and act as habitats for smaller organisms. As sea sponges, they have the ability to reproduce both sexually and asexually.
Rhytisma fulvum, the sulphur leather coral, is a species of colonial soft coral in the family Alcyoniidae. It is native to shallow reefs in the Red Sea and the Indo-Pacific region. It was first described by the Swedish naturalist Peter Forsskål in 1775.
Sarcophyton is a genus of corals in the family Alcyoniidae that are commonly kept in reef aquaria. Sarcophyton produces the toxic terpene macrolide sarcophytoxide which serves as an antifeedant and also provides advantage in competition with other corals as it reduces photosynthesis of the coral Acropora formosa. However, snail Ovula ovum eats Sarcophyton, probably detoxifying sarcophytoxide in the intestines.
Sinularia polydactyla, known as finger leather coral, is a species of soft coral in the family Alcyoniidae. Bio-active isolates called durumolides have been found in all samples of this coral.
Holothuria (Cystipus) cubana is a species of sea cucumber in the family Holothuriidae. This species was first described by Ludwig in 1875.
Pseudoceratina is a genus of sponge within the family Pseudoceratinidae. They are characterized by possession of a dendritic fiber skeleton lacking laminar bark but containing pith. They have been found in a variety of habitats including the Great Barrier reef, the Red Sea, and Jamaica. Sponges of this genus have a microbiome known to produce a variety of chemicals that are used in pharmaceutical and anti-fouling activities. Notably, a species in this genus produces a chemical that is effective in inhibiting the migration of metastatic breast cancer cells.
Aldersladum is a genus of the Alcyoniidae family. Aldersladum are Alcyonacea found from the Philippine Sea to the Indian Ocean. The genus was created from previously described corals with similar properties in 2011.
