Kunstformen Der Natur
(known in English as ''Art Forms in Nature'') is a book of lithographic and halftone prints by German biologist Ernst Haeckel. Publication Originally published in sets of ten between 1899 and 1904 and collectively in two volumes in 1904, it consists of 100 prints of various organisms, many of which were first described by Haeckel himself. Over the course of his career, over 1000 prints were produced based on Haeckel's sketches and watercolors; many of the best of these were chosen for , translated from sketch to print by lithographer Adolf Giltsch. A second edition of , containing only 30 prints, was produced in 1914. Themes According to Haeckel scholar Olaf Breidbach, the work was "not just a book of illustrations but also the summation of his view of the world." The over-riding themes of the plates are symmetry and level of organization. The subjects were selected to embody these to the full, from the scale patterns of boxfishes to the spirals of ammonites to the pe ...

Georges Cuvier
Jean Léopold Nicolas Frédéric, baron Cuvier (23 August 1769 – 13 May 1832), known as Georges Cuvier (; ), was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastr ...

Joshua Alder
Joshua Alder (7 April 1792 – 21 January 1867) was a British cheese, cheesemonger and amateur zoologist and malacologist. As such, he specialized in the Tunicata, and in gastropods. He was a member of the Hancock Museum, Natural History Society of Northumberland and Durham, and an early member of the Literary and Philosophical Society of Newcastle upon Tyne, alongside Joseph Swan and Robert Stephenson. He corresponded with Charles Darwin. His drawings are in the collections of the Great North Museum: Hancock and the British Museum. Ravensworth Terrace From 1841 to 1857 Alder was a tenant at 5 Ravensworth Terrace in the Summerhill area of Newcastle upon Tyne, which he shared with his sister Mary, a woman of independent means, and their two female servants. During this time, he ran a cheese shop in The Side, Newcastle upon Tyne, The Side, a street in central Newcastle. He sold that business and became a shareholder in the Northumberland District Bank, and a gentleman of leis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albany Hancock
Albany Hancock (24 December 1806 – 1873), English naturalist, biologist and supporter of Charles Darwin from Newcastle upon Tyne. He is best known for establishing a museum along with his brother John and for his works on marine animals and coal-measure fossils. Life and work Albany Hancock was born in Newcastle. His father John was also interested in natural history and on his death in 1812, when Albany was just six, his collections were retained and maintained by their mother. Their grandfather Thomas Hancock was a saddler and ironmonger. Three of the children, John, Mary, and Albany took an interest in natural history and John became particularly famous thanks to the exhibition of his work at the Great Exhibition of 1851. His childhood influences included a botanist Robertson, the ornithologists Wingate, Thomas Bewick and Joshua Alder. He showed skills at dissection and drawing and he helped Alder with his catalogue of land and freshwater shells (1830). He wrote his firs ...

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] |

Nudibranch
Nudibranchs () are a group of soft-bodied marine gastropod molluscs, belonging to the order Nudibranchia, that shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown", "marigold", "splendid", "dancer", "dragon", and "sea rabbit". About 3,000 species of nudibranchs are known.Ocean Portal (2017)A Collage of Nudibranch Colors Smithsonian National Museum of Natural History. Retrieved 17 April 2018. The word ''nudibranch'' comes from the Latin 'naked' and the Ancient Greek () ' gills'. Nudibranchs are often casually called sea slugs, as they are a family of opisthobranchs (sea slugs), within the phylum Mollusca (molluscs), but many sea slugs belong to several taxonomic groups that are not closely related to nudibranchs. A number of these other sea slugs, such as the photosynthetic '' Sacoglossa'' and the colourful Aglajidae, are often confused wi ...

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.

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.

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 ...
