Notomithrax Ursus
''Notomithrax ursus'', known as the hairy seaweed crab, is a spider crab of the family Majidae Majidae is a family of crabs, comprising around 200 marine species inside 52 genera, with a carapace that is longer than it is broad, and which forms a point at the front. The legs can be very long in some species, leading to the name "spider c .... Identification Species description This crustacean has a hard rounded-triangular shell, or carapace, that is covered in hair-like projections that vary in size. The shell's length is 1.3 times the size of its width, the shell's surface has many tubercles with spines running to the front of the shell going to the sides. The edges of the carapace have nine outward directed sharp spines: 3 supraorbital, 3 hepatic and 3 brachial. Two spines at the front of the crab's head form a V-shape and are covered with small bristles. Some of the bristles along the carapace are short and hooked while others are long and straight.

Johann Friedrich Wilhelm Herbst
Johann Friedrich Wilhelm Herbst (1 November 1743 – 5 November 1807) was a German naturalist and entomologist from Petershagen, Minden-Ravensberg. He served as a chaplain in the Prussian army. His marriage in Berlin, 1770, with Euphrosyne Luise Sophie (1742–1805), daughter of the Prussian ''Hofrat'' Libert Waldschmidt seems to have been childless. He was the joint editor, with , of ''Naturgeschichte der in- und ausländischen Insekten'' (1785–1806, 10 volumes), which was one of the first attempts at a complete survey of the order [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Spider Crab
The Majoidea are a superfamily of crabs which includes the various spider crabs. Taxonomy In "''A classification of living and fossil genera of decapod crustaceans''" De Grave and colleagues divided Majoidea into six families: * Family Epialtidae ** Subfamily Epialtinae ** Subfamily Pisinae ** Subfamily Pliosomatinae ** Subfamily Tychiinae * Family Hymenosomatidae * Family Inachidae * Family Inachoididae * Family Majidae ** Subfamily Eurynolambrinae ** Subfamily Majinae ** Subfamily Micromaiinae ** Subfamily Mithracinae ** Subfamily Planoterginae * Family Oregoniidae The classification has since been revised, with subfamilies Epialtinae and Mithracinae being elevated to families and Hymenosomatidae being moved to its own superfamily. The family composition according to the World Register of Marine Species is as follows: * family Epialtidae MacLeay, 1838 * family Inachidae MacLeay, 1838 * family Inachoididae Dana, 1851 * family Macrocheiridae Dana, 1851 * family Majida ...

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 ...

Majidae
Majidae is a family of crabs, comprising around 200 marine species inside 52 genera, with a carapace that is longer than it is broad, and which forms a point at the front. The legs can be very long in some species, leading to the name "spider crab". The exoskeleton is covered with bristles to which the crab attaches algae and other items to act as camouflage. Genera The roughly 200 extant and over 50 extinct species are divided among 52 genera in 5 subfamilies: '' Eurynolambrinae'' Števčić, 1994 *'' Eurynolambrus'' H. Milne-Edwards & Lucas, 1841 '' Majinae'' Samouelle, 1819 *'' Ageitomaia'' Griffin & Tranter, 1986 *'' Anacinetops'' Miers, 1879 *''Choniognathus'' Rathbun, 1932 *'' Cyclax'' Dana, 1851 *'' Entomonyx'' Miers, 1884 *''Eurynome'' Leach, 1814 *'' Jacquinotia'' Rathbun, 1915 *'' Kasagia'' Richer de Forges & Ng, 2007 *'' Kimbla'' Griffin & Tranter, 1986 *''Leptomithrax'' Miers, 1876 *'' Maiopsis'' Faxon, 1893 *'' Maja'' Lamarck, 1801 *'' Majella'' Ortmann, 1893 *'' M ...

Crustaceans Of Australia
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by ...
