Coralliidae
Coralliidae, also known as precious corals, is a taxonomic family of soft corals belonging to the phylum Cnidaria of the family Scleraxonia. These sessile corals are one of the most dominant members of hard-bottomed benthic environments such as seamounts, canyons and continental shelves. From this coral family results 69 descendants in which each species plays a key role in forming habitats for a variety of marine species. Due to their unique trait of possessing a red calcium carbonate skeleton, these corals can be harvested in order to create handcrafted amulets, jewelry and other valuable artifacts, giving rise to its reputed name of "precious corals". Correspondingly, members of this family are vulnerable to the negative impacts of overharvestation imposed by mass coral trade. Description Members of this family Coralliidae are also considered "soft corals" which are sedentary, colonial polypoids. Animals of this class have a simple cup shaped body that consists of two laye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scleraxonia
Scleraxonia is a suborder of corals, a member of the phylum Cnidaria. Characteristics Members of Scleraxonia have a skeletal axis made of calcified spicules, organic fibres or both, which may be separate, linked or fused together. Families and genera There are nine recognised families in this suborder and over thirty genera, with four families (Anthothelidae, Briareidae, Coralliidae and Subergorgiidae) containing some deep-water species and two families (Paragorgiidae and Parisididae) being exclusively deep water. Families and genera in this suborder include: * Anthothelidae Broch, 1916 ** '' Alertigorgia'' Kükenthal, 1908 ** '' Anthothela'' Verrill, 1879 ** '' Briareopsis'' Bayer, 1993 ** '' Erythropodium'' Kölliker, 1865 ** '' Iciligorgia'' Duchassaing, 1870 ** '' Lateothela'' Moore, Alderslade & Miller, 2017 ** '' Solenocaulon'' Gray, 1862 ** '' Stereogorgia'' ** '' Tubigorgia'' Pasternak, 1985 ** '' Williamsium'' Moore, Alderslade & Miller, 2017 * Briareidae Gray, 1859 ** ...

Corallium Rubrum
Precious coral, or red coral, is the common name given to a genus of marine corals, ''Corallium''. The distinguishing characteristic of precious corals is their durable and intensely colored red or pink-orange skeleton, which is used for making jewelry. Habitat Red corals grow on rocky seabottom with low sedimentation, typically in dark environments—either in the depths or in dark caverns or crevices. The original species, ''C. rubrum'' (formerly ''Gorgonia nobilis''), is found mainly in the Mediterranean Sea. It grows at depths from 10 to 300 meters below sea level, although the shallower of these habitats have been largely depleted by harvesting. In the underwater caves of Alghero, Sardinia (the "Coral Riviera") it grows at depth from 4 to 35 meters. The same species is also found at Atlantic sites near the Strait of Gibraltar, at the Cape Verde Islands and off the coast of southern Portugal. Other ''Corallium'' species are native to the western Pacific, notably a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mesentery (zoology)
In zoology, a mesentery is a membrane inside the body cavity of an animal. The term identifies different structures in different phylum, phyla: in vertebrates it is a double fold of the peritoneum enclosing the intestines; in other organisms it forms complete or incomplete partitions of the body cavity, whether that is the coelom or, as in the Anthozoa, the gastrovascular cavity. The word "mesentery" is derived from the Greek ''mesos'', "in the middle" and ''enteron'', an "intestine". Vertebrates In vertebrates, a mesentery is a membrane consisting of a double fold of peritoneum that encloses the intestines and their associated organs and connect them with the dorsal wall of the abdominal cavity. In invertebrates, a mesentery is a support or partition in a body cavity serving a similar function to the mesenteries of vertebrates. Bilateria In Bilateria, bilaterally symmetrical organisms there is often a major mesentery separating the two halves of the coelom. In segmented orga ...

Canary Islands
The Canary Islands (; es, Canarias, ), also known informally as the Canaries, are a Spanish autonomous community and archipelago in the Atlantic Ocean, in Macaronesia. At their closest point to the African mainland, they are west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and they are the most populous special territory of the European Union. The seven main islands are (from largest to smallest in area) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, and El Hierro. The archipelago includes many smaller islands and islets, including La Graciosa, Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It also includes a number of rocks, including those of Salmor, Fasnia, Bonanza, Garachico, and Anaga. In ancient times, the island chain was often referred to as "the Fortunate Isles". The Canary Islands are the southernmost region of Spain, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Archipelago
The Hawaiian Islands ( haw, Nā Mokupuni o Hawai‘i) are an archipelago of eight major islands, several atolls, and numerous smaller islets in the North Pacific Ocean, extending some from the island of Hawaii in the south to northernmost Kure Atoll. Formerly the group was known to Europeans and Americans as the Sandwich Islands, a name that James Cook chose in honor of the 4th Earl of Sandwich, the then First Lord of the Admiralty. Cook came across the islands by chance when crossing the Pacific Ocean on his Third Voyage in 1778, on board HMS ''Resolution''; he was later killed on the islands on a return visit. The contemporary name of the islands, dating from the 1840s, is derived from the name of the largest island, Hawaii Island. Hawaii sits on the Pacific Plate and is the only U.S. state that is not geographically connected to North America. It is part of the Polynesia subregion of Oceania. The state of Hawaii occupies the archipelago almost in its entirety (including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Region
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
