Cerithium Caeruleum
''Cerithium caeruleum'', the Cerith sand snail, is a species of sea snail, a marine gastropod mollusk in the family (biology), family Cerithiidae. It is generally found in large populations on intertidal rocky shores with a thin layer of sediments. They have large and solid shells, and their radula ribbon robust long about one-fifth the shell length. This species lives in the planktonic stage from 90 to 120 days and has a seven-year life history. This common intertidal species is confined to east Africa, Madagascar, and the Arabian Peninsula and is unlikely to be confused with any other ''Cerithium'' species. It is distinguished by its squat, knobby shape; and as indicated by its name, caeruleum, a grayish blue color with spiral rows of black tubercles. Description 1. Shell This species is widespread in the tropical Indo-Pacific (Red Sea, Kenya, Madagascar, Mozambique, Tanzania and Western India). The shell of ''Cerithium caeruleum'' is large, solid, stocky, knobby, reachin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Homonym (biology)
In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon. The rule in the International Code of Zoological Nomenclature is that the first such name to be published is the senior homonym and is to be used (it is " valid"); any others are junior homonyms and must be replaced with new names. It is, however, possible that if a senior homonym is archaic, and not in "prevailing usage," it may be declared a ''nomen oblitum'' and rendered unavailable, while the junior homonym is preserved as a ''nomen protectum''. :For example: :* Cuvier proposed the genus ''Echidna'' in 1797 for the spiny anteater. :*However, Forster had already published the name ''Echidna'' in 1777 for a genus of moray eels. :*Forster's use thus has priority, with Cuvier's being a junior homonym. :*Illiger published the replacement name ''Tachyglossus'' in 1811. Similarly, the International Code of Nomenclature for algae, fungi, and plants ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lectotype
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Cerithiidae
Cerithiidae, common name the cerithiids or ceriths, is a large family of medium-sized marine gastropods in the clade Sorbeoconcha. Distribution Ceriths are found worldwide on sandy bottoms, reef flats or coral reef rock covered with sand and algae in the sublittoral zone of warm or temperate waters. Most are found in tropical areas. A few occur along the European coastline and about 30 species in two genera are found along the American coast. A few species occur in estuarine areas of mangrove forests close to the sea. Only a few species of the subfamily Bittiinae are found in deep water. Diet Ceriths are herbivores and detritivores that graze the sea bed. Description Their slender shell is elongated with a pointed spire. They vary in size from 3 mm ('' Bittium alternatum'') to 150 mm ('' Cerithium nodulosum''). The smallest shells are found in the subfamily Bittiinae. The many whorls have radial sculpture with axial ridges and nodules. The aperture shows at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 opini ...
