Palicidae
The family Palicidae, sometimes called ''stilt crabs'', are a group of crabs. Some genera previously included in this family are now placed in a separate family, the Crossotonotidae. Genera The family Palicidae contains nine extant genera and two extinct genera : *'' Eopalicus'' Beschin, Busulini, De Angeli & Tessier, 1996 † *'' Exopalicus'' Castro, 2000 *'' Miropalicus'' Castro, 2000 *'' Neopalicus'' Moosa & Serène, 1981 *'' Palicoides'' Moosa & Serène, 1981 *'' Paliculus'' Castro, 2000 *''Palicus ''Palicus'' is a genus of stilt crabs in the family Palicidae.

Eugène Louis Bouvier
Eugène Louis Bouvier (9 April 1856, in Saint-Laurent-en-Grandvaux – 14 January 1944, in Paris) was a French entomologist and carcinologist. Bouvier was a professor at the Muséum national d'histoire naturelle. Biography Following graduation at the normal school in Lons-le-Saunier, he taught classes in Clairvaux, Versailles, Saint-Cloud and Villefranche-sur-Saône. From 1882 to 1887, he served as a "boursier" at the Muséum national d'histoire naturelle, where he studied with Alphonse Milne-Edwards (1835–1900) and Edmond Perrier (1844–1921). Together with Milne-Edwards, he worked on some of the crustaceans from the ''Travailleur'' and ''Talisman'' expeditions (1880–1883). In 1887, he earned his doctorate in natural sciences with a dissertation involving prosobranch gastropods, ''Système nerveux, morphologie générale et classification des Gastéropodes prosobranches''. In 1889 he became an associate professor at the ''Ecole supérieure de pharmacie de Paris'', and in 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crabs
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting " tail" ( abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as ... [...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 opi ...
