Megasurcula Carpenteriana
''Megasurcula carpenteriana'' (Gabb, 1865), also known as Carpenter's turrid, is a species of medium-sized predatory sea snail, a marine gastropod mollusc in the family Pseudomelatomidae, a family previously lumped with others collectively known as turrids. This species occurs in the Eastern Pacific Ocean. The species was named in honor of Philip Pearsall Carpenter. Subspecies Subspecies within this species include: *''Megasurcula carpenteriana fernandoana'' Description The shell is small, in the adult stage averaging about in length, against in length for the fully adult ''carpenteriana''. It is proportionately much heavier, the anal fasciole is more strongly constricted, and the appressed margin of the whorl does not approach as closely to the periphery of the preceding whorl as in that species. The periphery is often marked by a minutely beaded or undulate thread, and is more nearly midway between the sutures on the spire than in ''carpenteriana''. The aperture is shorte ...

William More Gabb
William More Gabb (January 16, 1839 – May 30, 1878) was an American paleontologist. Gabb was born and educated in Philadelphia, Pennsylvania, the leading center of American science at the time. He graduated from Jefferson Grammar School at age thirteen and was admitted to the prestigious Central High School of Philadelphia. He distinguished himself in his studies and showed an interest in natural history, conchology and geology. He graduated in 1857 with a bachelor of arts degree. Gabb chose to pursue a career in geology and sought the assistance of the notable geologist, James Hall in Albany, New York. For a time he became Hall's student and assistant before returning to Philadelphia in 1860. There he became an active member of the Academy of Natural Sciences and then briefly joined a group of young scientists studying at the Smithsonian Institution in Washington D.C . In 1861, Josiah Whitney, chief of the California Geological Survey, was searching for a qualified pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .

Philip Pearsall Carpenter
Philip Pearsall Carpenter (4 November 1819 – 24 May 1877) was an English minister who emigrated to Canada, where his field work as a malacologist or conchologist is still well regarded today. A man of many talents, he wrote, published, taught, and was a volunteer explaining the growing study of shells in North America. Life Philip P. Carpenter was born in Bristol, England on 4 November 1819. His father was Lant Carpenter, a notable educator and Unitarian minister. His mother was Anna or Hannah Penn, daughter of John Penn and Mary. Anna was christened on 11 May 1787 in Bromsgrove, Worcester.Carpenters' Encyclopedia of Carpenters 2009, DVD format.

Pseudomelatomidae
Pseudomelatomidae is a family (biology), family of predatory sea snails, marine gastropods included in the superfamily Conoidea (previously Conacea) and part of the Neogastropoda (Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), Bouchet & Rocroi, 2005). In 1995 Kantor elevated the subfamily Pseudomelatominae to the status of family Pseudomelatomidae. In 2011 Philippe Bouchet, Bouchet, Kantor ''et al''. moved the Crassispirinae and Zonulispirinae and numerous genera of snails loosely called Turridae, turrid snails (which at that point had been placed in the family Conidae) and placed them in the family Pseudomelatomidae. This was based on a cladistic analysis of shell morphology (biology), morphology, radula, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments. Genera Genera within the family Pseudomelatomidae include: * ''Abyssocomitas'' Sysoev & Kantor, 1986 * ''Aguilaria'' Taylor & Wells, 1994 * ''Anticomitas'' ...

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] |
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 ...

Mollusc
Mollusca is a phylum of protostome, protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant taxon, 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 biology, 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 mollusc, freshwater and even terrestrial molluscs, terrestrial species. The phylum is typically divided into 7 or 8 taxonomy (biology), taxonomic class (biology), classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurobiology, neurologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
