Sinularia polydactyla, known as finger leather coral, is a species of soft coral in the family Alcyoniidae. [1] Bio-active isolates called durumolides have been found in all samples of this coral. [2]
Corals are marine invertebrates within the class 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.
Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals and soft corals. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton. The basic unit of the adult is the polyp; this consists of a cylindrical column topped by a disc with a central mouth surrounded by tentacles. Sea anemones are mostly solitary, but the majority of corals are colonial, being formed by the budding of new polyps from an original, founding individual. Colonies are strengthened by calcium carbonate and other materials and take various massive, plate-like, bushy or leafy forms.
Normanby Island in North Queensland, Australia is part of the Frankland Islands 30 km north-east of Babinda, and south-east of Cairns. The Frankland Islands are teeming with permanent and migratory marine life, especially the green sea turtle which nests on the island. Normanby Island, part of the Frankland Islands group offers a comprehensive reef system with a tropical island. The islands are very popular with reef tour operators working from Cairns. It is around 7 hectares or 0.07 square km in size.
The Aliwal Shoal is a rocky reef which is the remains of an ancient sand dune approximately 5 kilometres (3.1 mi) off the coast of KwaZulu-Natal, South Africa. The reef is inhabited by many kinds of hard and soft corals and other marine invertebrates, and a variety of tropical and subtropical fish species. Aliwal Shoal was named after the near-sinking in 1849 of the three-masted vessel Aliwal, captained by James Anderson. There are two wrecks near the reef that are popular recreational dive sites. The Norwegian bulk carrier MV Produce sank in 1974, and SS Nebo sank in 1884. Aliwal Shoal has diverse marine life, including large predators, and is popular as a recreational scuba diving destination. The Shoal is known especially for its abundance of Grey nurse sharks between July and November when the sharks congregate there to mate.
McKean Island is a small, uninhabited island in the Phoenix Islands, Republic of Kiribati. Its area is 57 hectares.
Alcyonacea, or soft corals, are an order of corals. In addition to the fleshy soft corals, the order Alcyonacea now contains all species previously known as "gorgonian corals", that produce a more or less hard skeleton, though quite different from "true" corals (Scleractinia). These can be found in suborders Holaxonia, 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.
The teardrop butterflyfish is a species of marine ray-finned fish, a butterflyfish belonging to the (family Chaetodontidae. It is found in the Indo-Pacific region.
Octocorallia is a subclass of Anthozoa comprising around 3,000 species of water-based organisms formed of colonial polyps with 8-fold symmetry. It includes the blue coral, soft corals, sea pens, and gorgonians within three orders: Alcyonacea, Helioporacea, and Pennatulacea. These organisms have an internal skeleton secreted by mesoglea and polyps with eight tentacles and eight mesentaries. As with all Cnidarians these organisms have a complex life cycle including a motile phase when they are considered plankton and later characteristic sessile phase.
Pigeon Island National Park is one of the two marine national parks of Sri Lanka. The national park is situated 1 km off the coast of Nilaveli, a coastal town in Eastern Province, encompassing a total area of 471.429 hectares. The island's name derives from the rock pigeon which has colonized it. The national park contains some of the best remaining coral reefs of Sri Lanka. Pigeon Island was designated as a sanctuary in 1963. In 2003 it was re-designated as a national park. This national park is the 17th in Sri Lanka. The island was used as a shooting range during the colonial era. Pigeon Island is one of the several protected areas affected by the Indian Ocean tsunami in 2004.
Wakatobi National Park is a marine national park in Southeast Sulawesi, Indonesia. The name of Wakatobi is a portmanteau of the four main Tukangbesi Islands: Wangi-wangi, Kaledupa, Tomia, and Binongko. Since 2005 the park is listed as a tentative World Heritage Site.
The Phoenix Islands Protected Area (PIPA) is located in the Republic of Kiribati, an ocean nation in the central Pacific approximately midway between Australia and Hawaii. PIPA constitutes 11.34% of Kiribati's exclusive economic zone (EEZ), and with a size of 408,250 km2 (157,630 sq mi), it is one of the largest marine protected areas (MPA) and one of the largest protected areas of any type on Earth. The PIPA was also designated as the world's largest and deepest UNESCO World Heritage Site in 2010.
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.
Phyllodesmium guamense is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusc in the family Facelinidae.
Phyllodesmium magnum is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusc in the family Facelinidae.
Alcyoniidae is a family of leathery or soft corals in the phylum Cnidaria.
Sinularia is a genus of soft coral in the family Alcyoniidae. They are commonly known as leather corals and currently have 166 described species in the genus.
Sinularia flexibilis is a species of soft coral in the family Alcyoniidae. It is known commonly as the spaghetti finger leather coral. This species is widespread throughout the western Pacific and eastern Indian Oceans. It is usually found in large colonies at depths between one and fifteen meters.
Piti Bomb Holes Marine Preserve is a marine protected area comprising all of Piti Bay on the western coast of Guam, located off of the village of Piti in the Philippine Sea. The defining "bomb hole" features, named because they look like bomb craters in the reef flat, are actually natural percolation pits where fresh water filters into the shallow lagoon at a depth of 25 to 30 feet. The largest pit houses the commercial Fish Eye Marine Park tourist attraction, which includes a wooden pier to a underwater observatory and a Seawalker tour of the lagoon bottom. It is visited by more than 200,000 people annually. The Piti preserve is the most ecologically diverse of Guam's five marine preserves. The pit around Fish Eye is a popular snorkeling and recreational diving site.
