Description ''Cryptoconchus porosus'' is a large chiton reaching a length of about . The eight valves A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.

These are pale blue or white on top, sometimes sky blue underneath, and when removed from the animal they each resemble a butterfly giving the common name. The girdle is fleshy and smooth with short sutural bristles that protrude from 18 rounded pores, which are elevated and run in two crested rows from head to tail. The colour of the dorsal surface can range from dark brown to bright orange, while the un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henri Marie Ducrotay De Blainville
Henri Marie Ducrotay de Blainville (; 12 September 1777 – 1 May 1850) was a French zoologist and anatomist. Life Blainville was born at Arques, near Dieppe. As a young man he went to Paris to study art, but ultimately devoted himself to natural history. He attracted the attention of Georges Cuvier, for whom he occasionally substituted as lecturer at the Collège de France and at the Athenaeum Club, London. In 1812 he was aided by Cuvier in acquiring the position of assistant professor of anatomy and zoology in the Faculty of Sciences at Paris. Eventually, relations between the two men soured, a situation that ended in open enmity. In 1819, Blainville was elected a member of the American Philosophical Society in Philadelphia. In 1825 he was admitted a member of the French Academy of Sciences; and in 1830 he was appointed to succeed Jean-Baptiste Lamarck in the chair of natural history at the museum. Two years later, on the death of Cuvier, he obtained the chair of comparat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henry Suter
Henry Suter (born Hans Heinrich Suter, 9 March 1841 – 31 July 1918) was a Swiss-born New Zealand zoologist, naturalist, palaeontologist, and malacologist. Biography Henry Suter was born on 9 March 1841 in Riesbach, Zurich, Switzerland, and was the son of a prosperous silk-manufacturer of Zurich. He was educated at the local school and university, being trained as an analytical chemist. Suter joined his father's business, and for some years he engaged in various commercial pursuits. From his boyhood, Henry Suter was deeply interested in natural history. He enjoyed the friendship and help of such men as Dr. Auguste Forel, Professor Paul Godet, the brothers de Saussure (linguist Ferdinand de Saussure, Sinolog and astronomer Léopold de Saussure and René de Saussure Esperantist and scientist), Escher von der Linth, and especially the well-known conchologist, Dr. Albert Mousson. Partly to improve his financial prospects and partly lured by the attraction of the fauna of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Acanthochitonidae
Acanthochitonidae is a family of chitons, marine molluscs in the class Polyplacophora. Description These small to large chitons are characterised by a broad girdle with erect tufts of up to ten large bristles. The coarsely granular valves of the shell are partially overlapped by the girdle. This girdle is all covered by coarse spines. The articulating flange, or ''articulamentum'', is well developed. The margin of the cephalic plate has about five slits. The lateral'' insertion plates'' all have a single notch.
