Obtortionidae
Obtortionidae is a family of sea snails, marine gastropod molluscs in the superfamily Cerithioidea, that is within the clade Cerithimorpha or in clade Sorbeoconcha. The shell of the larva is ornamental. 2005 taxonomy According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Obtortionidae has been recognized as a synonym of family Scaliolidae within clade Caenogastropoda/clade Sorbeoconcha/Superfamily Cerithioidea. Finellidae has been also a synonym of Scaliolidae. 2006 taxonomy Bandel (2006)Bandel K. (2006).

Finella
''Finella'' is a genus of sea snails, marine gastropod mollusks in the family Scaliolidae. This genus has been assigned in the course of time to different families by different authors: Rissoidae, Cerithiidae, Dialidae, Obtortionidae, Finellidae and Diastomatidae Morphological and anatomical studies by Winston Ponder in 1994 established that the genera ''Finella'' and ''Scaliola'' didn't belong in the above-mentioned families and he brought them in a new family Scaliolidae. This was supported in 1982 by Healy through the study of the ultrastructure on the spermatozoa. Description The species in this genus contain a small, elongated, conical shell without siphonal canal. The axial to spiral sculpture varies between weak and strong. Distribution The snails of this species are common to even abundant in shallow waters of the tropical Indo-West Pacific Ocean. Species Species within the genus ''Finella'' include: * ''Finella adamsi'' (Dall, 1889) * '' Finella barbarensis'' (Bartsc ...

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Clathrofenella
''Cerithidium'' is a genus of sea snails, marine gastropod mollusks in the family Cerithiidae. The genus has been used as valid for Indo-Pacific species following Hasegawa (1998), on the grounds that it is older than ''Clathrofenella'' Kuroda & Habe, 1952. However, the Mediterranean type species is a ''Bittium'', for which reason this generic assignment should be revised. The opinion of Hasegawa (1998) and van Aartsen (2006) is followed here Species Species within the genus ''Cerithidium'' include: * '' Cerithidium actinium'' Rehder, 1980 * '' Cerithidium australiense'' Thiele, 1930 * '' Cerithidium cerithinum'' (Philippi, 1849) * '' Cerithidium californica'' * '' Cerithidium diplax'' (Watson, 1886) * † '' Cerithidium fragrans'' Barnard, 1963 * '' Cerithidium fuscum'' (A. Adams, 1860) * '' Cerithidium liratum'' Thiele, 1930 * † '' Cerithidium perminimum'' (de Boury, 1900) * ''Cerithidium perparvulum ''Cerithidium perparvulum'' is a species of sea snail, a marine gastr ...

Freiberger Forschungshefte
The Freiberger, also known as Franches-Montagnes, is a horse breed from Switzerland, from the Jura region, described as either a "heavy warmblood" or a "light coldblood". It was widely used as draft and pack horse in the Swiss army. It has a good disposition and is versatile, suitable for both driving and riding. Each year at the ''Marché Concours'' in Saignelégier in the Franches-Montagnes district of the Swiss canton of Jura, on the second weekend in August, a variety of shows and competitions are held. Breed characteristics History The presence of an autochthonous horse breed in the Jura traces to the year 1619. By the early 19th century, there were active breeders in the district of Franches-Montagnes. In 1817, there were 4,000 breeding mares on record. The horses were bred for use in agriculture and by the army as pack animals and artillery draft horses. There are records of imports of Anglo-Norman horses for the year 1821, and of other horses from England, Fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.
