Haliotis Jacnensis
''Haliotis jacnensis'', common name Jacna abalone, is a species of sea snail, a marine gastropod mollusk in the family Haliotidae, the abalone Abalone ( or ; via Spanish , from Rumsen language, Rumsen ''aulón'') is a common name for any small to very large marine life, marine gastropod mollusc in the family (biology), family Haliotidae, which once contained six genera but now cont .... Description The shell size varies between 7 mm and 25 mm. The oblong-ovate shell is spirally peculiarly rudely ridged. The ridges are very irregular and rather scaly, somewhat smooth next the perforations which are slightly tubiferous and distant. The coloration is reddish-orange. The interior surface is silvery. This is a very characteristic species, to which there is little or no approximation in any other.

Lovell Augustus Reeve
Lovell Augustus Reeve (19 April 1814 – 18 November 1865) was an English conchologist and publisher. Life Born at Ludgate Hill, London, on 19 April 1814, he was the son of Thomas Reeve, draper and mercer, and Fanny Reeve, née Lovell. After attending school at Stockwell, he was apprenticed at the age of 13 to Mr. Graham, a local grocer. The chance purchase of shells led to a lifelong interest in conchology. In 1833 he attended the meeting of the British Association for the Advancement of Science at Cambridge. At the end of his apprenticeship Reeve visited Paris, where he read a paper on the classification of Mollusca before the Academy of Sciences. On his return to London, he wrote his first book, ''Conchologia Systematica'' (2 vols. London, 1841–2). From 1842, he traded as a natural history dealer. Using profits made by the sale of Dutch Governor-General of the Moluccas Van Ryder's collection from the Moluccas, which he purchased at Rotterdam Rotterdam ( , ; ; ) ...

César Marie Félix Ancey
César Marie Félix Ancey (15 November 1860 – 10 October 1906) was a French conchologist and entomologist. For 23 years Ancey was 'conservateur' of collections for Charles Oberthür (1845–1924) at Rennes. Ancey was then a 'fonctionnaire' at Mascara until his death.Anthony Musgrave (1932). Bibliography of Australian Entomology, 1775-1930, with biographical notes on authors and collectors, Royal Zoological Society of News South Wales (Sydney) : viii + 380. The genus '' Anceya'' was dedicated to him by Jules René Bourguignat. Biography César Marie Félix Ancey, administrator at Mascara, Algeria, was born in Marseille, France, 15 November 1860. His father, well known for his publications on entomology and author of valuable work on malacology, encouraged his well-developed inclination for zoological studies. At the age of twenty-three he was appointed conservator of the fine Oberthur entomological collection at Rennes. This position not promising material success, he retur ...

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] |
Sea Snail
Sea snails are slow-moving marine (ocean), marine gastropod Mollusca, molluscs, usually with visible external shells, such as whelk or abalone. They share the Taxonomic classification, taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible Gastropod shell, shell. Definition Determining whether some gastropods should be called sea snails is not always easy. Some species that live in brackish water (such as certain Neritidae, neritids) can be listed as either freshwater snails or marine snails, and some species that live at or just above the high tide level (for example, species in the genus ''Truncatella (gastropod), Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large and diverse group of animals. Most snails that live in salt water respire using a gill or gills; a few species, though, have a lung, are intertidal, and are active only at low tide w ...

Gastropod
Gastropods (), commonly known as slugs and snails, belong to a large Taxonomy (biology), taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, freshwater, and from the land. There are many thousands of species of sea snails and sea slug, slugs, as well as freshwater snails, freshwater limpets, land snails and slugs. The class Gastropoda is a diverse and highly successful class of mollusks within the phylum Mollusca. It 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 Furongian, Late Cambrian. , 721 family (taxonomy), families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently neontology, extant living fossil, with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusk
Mollusca is a phylum of protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and 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. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater and even terrestrial species. 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 extant i ...

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 ...

Haliotidae
''Haliotis'', common name abalone, is the only genus in the family Haliotidae. This genus once contained six subgenera. These subgenera have become alternate representations of ''Haliotis''. The genus consists of small to very large, edible, herbivorous sea snails, marine gastropod molluscs. The number of species recognized worldwide ranges between 30 and 130, with over 230 species-level taxa described. The most comprehensive treatment of the family considers 56 species valid, with 18 additional subspecies. Other common names are ear shells, sea ears, and, rarely, muttonfish or muttonshells in parts of Australia, ormer in the UK, perlemoen in South Africa, and the Māori name for three species in New Zealand is pāua. Description The shells of abalone have a low, open, spiral structure, and are characterized by having several open respiratory pores in a row near the shell's outer edge. The thick inner layer of the shell is composed of nacre, which in many species of abal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
