Gnathia Marleyi
''Gnathia marleyi'' is a species of crustacean in the family Gnathiidae. It is named after reggae musician Bob Marley. It is a parasite that infests and feeds on the blood of such fish as the French grunt (''Haemulon flavioliniatum''). This tiny species is only found in the Caribbean Sea. It only eats while in the juvenile stage. It can be found hiding among sea sponges, algae, and pieces of dead coral. Description The cephalosome of adult male specimens has a distinct produced frontal border with conical superior fronto-lateral processes with a slightly sunken inferior conical medio-frontal process. The dentate blades of the Mandible (arthropod mouthpart), mandibles each contain ten or eleven processes, with the overall mandible being .8 times the length of the cephalasome. The cephalosome of adult females is rectangular with convex lateral margins. It is 1.2 times as wide as it is long, and has no paraocular ornamentation. The frontal border is broadly rounded, slightly concave ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crustacean
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 th ...

Mandible (arthropod Mouthpart)
image:Bullant head detail.jpg, 250px, The mandibles of a bull ant The mandible (from la, mandibula or mandĭbŭ-lum, a jaw) of an arthropod is a pair of Arthropod mouthparts, mouthparts used either for biting or cutting and holding food. Mandibles are often simply called jaws. Mandibles are present in the extant subphylum, subphyla Myriapoda (millipedes and others), Crustacean, Crustacea and Hexapoda (insects etc.). These groups make up the clade Mandibulata, which is currently believed to be the sister group to the rest of arthropods, the clade Arachnomorpha (Chelicerata and Trilobite, Trilobita). Unlike the chelicerae of arachnids, mandibles can often be used to chew food. Mandibulates also differ by having Antenna (biology), antennae, and also by having three distinct body regions: head, thorax and abdomen. (The cephalothorax (or prosoma) of chelicerates is a fusion of head and thorax.) Insects Insect mandibles are as diverse in form as their food. For instance, grass ...

Cymothoida
Cymothoida is the name of a suborder of isopod crustaceans with a mostly carnivorous or parasitic lifestyle. It contains more than 2,700 described species in four superfamilies. Members of the suborder are characterised by their specialised mouthparts which include a mandible with a tooth-like process which is adapted for cutting or slicing. Classification Cymothoida contains these superfamilies and families: *Superfamily Anthuroidea Leach, 1814 ** Antheluridae Poore & Lew Ton, 1988 ** Anthuridae Leach, 1814 ** Expanathuridae Poore, 2001 ** Hyssuridae Wägele, 1981 ** Leptanthuridae Poore, 2001 ** Paranthuridae Menzies & Glynn, 1968 *Superfamily Cymothooidea Leach, 1814 **Aegidae White, 1850 **Anuropidae Stebbing, 1893 ** Barybrotidae Hansen, 1890 **Cirolanidae Dana, 1852 ** Corallanidae Hansen, 1890 ** Cymothoidae Leach, 1818 **Gnathiidae Leach, 1814 ** Protognathiidae Wägele & Brandt, 1988 ** Tridentellidae Bruce, 1984 *Superfamily Cryptoniscoidea Kossmann, 1880 **Asconisc ...

List Of Organisms Named After Famous People (born 1900–1949)
In biological nomenclature, organisms often receive scientific names that honor a person. A taxon (e.g. species or genus; plural: taxa) named in honor of another entity is an eponym, eponymous taxon, and names specifically honoring a person or persons are known as patronym (taxonomy), patronyms. Scientific names are generally formally published in peer-reviewed journal articles or larger monographs along with descriptions of the named taxa and ways to distinguish them from other taxa. Following rules of Latin grammar, species or subspecies names derived from a man's name often end in ''-i'' or ''-ii'' if named for an individual, and ''-orum'' if named for a group of men or mixed-sex group, such as a family. Similarly, those named for a woman often end in ''-ae'', or ''-arum'' for two or more women. This list is part of the List of organisms named after famous people, and includes organisms named after famous individuals born between 1 January 1900 and 31 December 1949. It also incl ...
