Neptune's Cup Sponge
''Cliona patera'', commonly called Neptune's cup sponge, is a species of demosponge in the family Clionaidae. Among the larger known sponges at up to a meter in height and width, the common name ''Neptune's cup'' refers to its characteristic wine glass shape and the Roman god of the sea. The species was thought to be extinct since late 1900s due to overharvesting, but live specimens were discovered in 2011 off the coast of Singapore and Thailand. Later they were transported so they can be close enough to reproduce. Another population was later found in Cambodia Cambodia, officially the Kingdom of Cambodia, is a country in Southeast Asia on the Mainland Southeast Asia, Indochinese Peninsula. It is bordered by Thailand to the northwest, Laos to the north, and Vietnam to the east, and has a coastline .... In the early 1900s, they were used as baby baths because they grew so large.

Thomas Hardwicke
Major-General Thomas Hardwicke (1756 – 3 March 1835) was an English soldier and natural history, naturalist who was in India from 1777 to 1823. He collected numerous specimens of natural history and had them painted by Indian artists. From these paintings many new species were described. Several of these species are named after him. On returning to England he collaborated with the zoologist John Edward Gray to publish ''Illustrations of Indian Zoology'' (1830–1835). Biography Hardwicke joined the British East India Company army with the Bengal Artillery as a Lieutenant Fireworker on 3 November 1778. He was posted in southern India from 1781 to 1785 serving under Colonel Pearce and Sir Eyre Coote (East India Company officer), Eyre Coote. He was in the field during the campaign against Tipu Sultan in 1790–1792. He saw action in the Relief of Vellore (10 January 1782), the Siege of Cuddalore (June 1783) and in the Rohilla Campaign (26 October 1794). He was wounded at Satyaman ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demosponge
Demosponges or common sponges are sponges of the class Demospongiae (from + ), the most diverse group in the phylum Porifera which include greater than 90% of all extant sponges with nearly 8,800 species A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction.

Being siliceous sponges, they are predominantly sponge#leuconoid, leuconoid in structure with an endoskeleton made of a meshwork of sponge spicule, spicules consisting of fibers of the protein spongin, the mineral silica, or both. Where spicules of silica are present, they have a different shape from those in the otherwise similar glass sponges. Some species, in particular from the Antarctic, obtain the silica for spicule-building from the ingestion of diatoms. The m ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Wine Glass
A wine glass is a type of Glass (drinkware), glass that is used for drinking or wine tasting, tasting wine. Most wine glasses are stemware (goblets), composed of three parts: the bowl, stem, and foot. There are a wide variety of slightly different shapes and sizes, some considered especially suitable for particular types of wine. Some authors recommend one holds the glass by the stem, to avoid warming the wine and smudging the bowl; alternately, for red wine it may be good to add some warmth. Before "glass" became adopted as a word for a glass drinking vessel, a usage first recorded in English c. 1382, wine was drunk from a wine cup, of which there were a Cup#History, huge variety of shapes over history, in many different materials.

Neptune (mythology)
Neptune ( ) is the god of freshwater and the sea in the Roman religion. He is the counterpart of the Greek god Poseidon.''Larousse Desk Reference Encyclopedia'', The Book People, Haydock, 1995, p. 215. In the Greek-inspired tradition, he is a brother of Jupiter and Pluto, with whom he presides over the realms of heaven, the earthly world (including the underworld), and the seas. Salacia is his wife. Depictions of Neptune in Roman mosaics, especially those in North Africa, were influenced by Hellenistic conventions. He was likely associated with freshwater springs before the sea; his festival, '' Neptunalia'', took place on July 23, during the peak of summer when water was scarcest. Like Poseidon, he was also worshipped by the Romans as a god of horses, ''Neptunus equestris,'' who was also a patron of horse-racing. Worship The theology of Neptune is limited by his close identification with the Greek god Poseidon, one of many members of the Greek pantheon whose theol ...

Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Overharvesting
Overexploitation, also called overharvesting or ecological overshoot, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife. In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at an unsustainable rate, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology, the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. The term is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Singapore
Singapore, officially the Republic of Singapore, is an island country and city-state in Southeast Asia. The country's territory comprises one main island, 63 satellite islands and islets, and one outlying islet. It is about one degree of latitude () north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south along with the Riau Islands in Indonesia, the South China Sea to the east, and the Straits of Johor along with the State of Johor in Malaysia to the north. In its early history, Singapore was a maritime emporium known as '' Temasek''; subsequently, it was part of a major constituent part of several successive thalassocratic empires. Its contemporary era began in 1819, when Stamford Raffles established Singapore as an entrepôt trading post of the British Empire. In 1867, Singapore came under the direct control of Britain as part of the Straits Settlements. During World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
