Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Chiton
Chitons () are marine molluscs of varying size in the class Polyplacophora (), formerly known as Amphineura. About 940 extant and 430 fossil species are recognized. They are also sometimes known as gumboots or sea cradles or coat-of-mail shells or suck-rocks, or more formally as loricates, polyplacophorans, and occasionally as polyplacophores. Chitons have a shell composed of eight separate shell plates or valves. These plates overlap slightly at the front and back edges, and yet articulate well with one another. Because of this, the shell provides protection at the same time as permitting the chiton to flex upward when needed for locomotion over uneven surfaces, and even allows the animal to curl up into a ball when dislodged from rocks. The shell plates are encircled by a skirt known as a girdle. Habitat Chitons live worldwide, from cold waters through to the tropics. They live on hard surfaces, such as on or under rocks, or in rock crevices. Some species live quite hi ... [...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 ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List of ...

Acanthopleura Echinata
''Acanthopleura echinata'' is a Southeast Pacific species of edible chiton, a marine polyplacophoran mollusc in the family Chitonidae, the typical chitons. Description ''Acanthopleura echinata'' is a very large chiton, with specimen confirmed at length of up to . In Chile, the largest individuals are in the north and the smallest in the south. The species is very dark reddish-brown. The plated shell, which often is covered in epibionts like algae, ''Scurria'' limpets and '' Mytilus'' mussels, has many spines. These spines are generally up to long in large individuals, but can be even longer if not broken, which however is unusual. The similar-sized '' Enoplochiton niger'' of the same region lacks the spines. Distribution, habitat and behavior The distribution of ''Chiton magnificus'' ranges along the Pacific coast of South America from Concepción Province (Punta Tumbes) in Chile to Talara in Peru.

Acanthopleura Granulata
''Acanthopleura granulata'', common name the West Indian fuzzy chiton (also known as Curbs or Sea Cradles), is a medium-sized tropical species of chiton. This type of chiton's activity does not depend on spring-neap oscillations leading to lower locomotion loss.Focardi, S., & Chelazzi, G. (1990). Ecological determinants of bioeconomics in three intertidal chitons (Acanthopleura spp.). Journal of Animal Ecology, 49(1), 347-362. Its morphology is different from usual chitons as it has a fifth valve, which is split into halves.Kingston, A., Sigwart, J., Chappell, D., & Speiser, D. (2019). Monster or multiplacophoran: A teratological specimen of the chiton Acanthopleura granulata (Mollusca: Polyplacophora) with a valve split into independent and symmetrical halves. Acta Zoologica, Acta Zoologica, 03/18/2019. This species is common within its range in the tropical Western Atlantic, but it is often not noticed, because its color and texture are similar to the rocks on which it lives. Wit ...
