Lyncina Sulcidentata
''Lyncina sulcidentata'', common name the square-toothed cowry or groove-toothed cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family (biology), family Cypraeidae, the cowries. Description The shells of these quite uncommon cowries reach on average of length, with a minimum size of and a maximum size of . The dorsum surface is smooth and shiny, the basic color is reddish or brown-orange, with three wide blue-gray transversal bands. The base is white or light brown, with long teeth furrowing the base (hence the Latin name ''sulcidentata''). The shell is quite similar to ''Lyncina schilderorum'', ''Lyncina carneola'' and ''Lyncina ventriculus''. In the living cowries mantle is brownish, with long bluish tree-shaped sensorial papillae. Mantle and foot are well developed, with external antennae. The lateral flaps of the mantle may hide completely the shell surface and may be quickly retracted into the shell.

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Lyncina Schilderorum
''Lyncina schilderorum'', common names the sandy cowry or Schilder's cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries. This species was named in honor of Franz and Maria Schilder, two German cowry biologists (hence the Latin name ''Schindlerorum'', meaning ''Schilder's''). Description The shells of these quite uncommon cowries reach on average of length, with a minimum size of and a maximum size of . The surface is smooth and shiny, their basic color is brown-orange, with 3-5 wide light blue transversal bands. The base is whitish or bluish, with fine white teeth. The shell is quite similar to '' Lyncina sulcidentata'', ''Lyncina carneola'' and ''Lyncina ventriculus''. In the living cowries mantle is whitish, with long tree-shaped sensorial papillae. Mantle and foot are well developed, with external antennae. The lateral flaps of the mantle may hide completely the shell surface and may be quickly retracted into the she ...

James Cosmo Melvill (naturalist)
James Cosmo Melvill (1 July 1845 – 4 November 1929) was a British botanist and malacologist who collected plants in Europe and North America. Family Melvill was born at Hampstead, London, on 1 July 1845. He was a grandson of British administrator in India, Sir James Cosmo Melvill (1792–1861), his father being the latter's second son, also James Cosmo Melvill (1821–1880), onetime assistant Under-Secretary of state for India.

Hawaiian Islands
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 (i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cypraeidae - Lyncina Sulcidentata - Hawaii-2
Cypraeidae, commonly named the cowries ( cowry), is a taxonomic family of small to large sea snails. These are marine gastropod mollusks in the superfamily Cypraeoidea, the cowries and cowry allies. Shell description Cypraeidae have adult shells which are very rounded, almost like an egg; they do not look like a typical gastropod shell. In virtually all of the species in the family Cypraeidae, the shells are extremely smooth and shiny. This is because in the living animal, the shell is nearly always fully covered with the mantle. Typically, no spire is visible in the fully adult shell, and there is a long, narrow, aperture which is lined with "teeth". Juvenile cowry shells are not at all similar to adult cowry shells. The juvenile shells of cowries perhaps more closely resemble the shells of some "bubble snails" in the order Cephalaspidea. Also the shells of juvenile cowries seldom exhibit the same color patterns as the adult shells do, and thus can be hard to identify to sp ...

Lyncina Ventriculus
''Lyncina ventriculus'', the ventral cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries. Description The shells of these uncommon cowries reach on average of length, with a minimum size of and a maximum size of . The shape of these smooth and shiny shells is usually oval, the dorsum surface is generally reddish brown, with four dark brown transversal bands, while the sides are definitely chocolate brown and present several vertical thin lines. The base may be white, pale pink or pale brown, the aperture is long and narrow, with short teeth on both lips. The shell is quite similar to ''Lyncina schilderorum'', '' Lyncina carneola'' and '' Lyncina sulcidentata''. In the living cowries the mantle is dark-grey, with clearer sensorial papillae. Distribution This species is distributed in the eastern Indian Ocean (Malaysia, Eastern Indonesia, Cocos Islands and Christmas Island), in the Central and Western Pacific Ocean ( ...

Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest prot ...

Family (biology)
Family ( la, familia, plural ') 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". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...
