Ampharetinae
Ampharetinae are a subfamily of terebellid "bristle worm" ( class Polychaeta). They are the largest subfamily of the Ampharetidae, of which they contain the great majority of the described genera. The majority of ampharetines are marine organisms like usual for polychaetes. However, some members of this subfamily are among the rare euryhaline polychaetes, inhabiting brackish and freshwater habitat. They are generally smallish deposit feeders which frequently live in small tubes they build from mud or similar substrate, or burrow in the sand. Genera The World Register of Marine Species recognizes the following 47 genera: * '' Abderos'' Schüller & Jirkov, 2013 * '' Adercodon'' Mackie, 1994 * '' Alkmaria'' Horst, 1919 * '' Ampharana'' Hartman, 1967 * '' Ampharete'' Malmgren, 1866 * '' Amphicteis'' Grube, 1850 * '' Amythas'' Benham, 1921 * '' Amythasides'' Eliason, 1955 * '' Andamanella'' Holthe, 2002 * '' Anobothrus'' Levinsen, 1884 * '' Auchenoplax'' Ehlers, 1887 * '' Decemunci ...

Ampharetidae
Ampharetidae are a family of terebellid "bristle worm" (class Polychaeta). As such, they belong to the order Canalipalpata, one of the three main clades of polychaetes. They appear to be most closely related to the peculiar alvinellids (Alvinellidae) which inhabit the deep sea, and somewhat less closely to the well-known trumpet worms (Pectinariidae). These three appear to form one of the main clades of terebellids. Almost all are (like polychaetes in general) marine organisms; some inhabit brackish or freshwater though. Most are smallish deposit feeders which frequently live in small tubes they build from mud or similar substrate, or burrow in the sand. Subfamilies and genera In 2001, Rouse and Pleijel divided the Ampharetidae into three subfamilies: the large Ampharetinae, the much smaller Melinninae, and the monotypic Uschakovinae. Also, there are some ampharetid genera '' incertae sedis'' or in a quite basal position: * ''Aryandes'' * '' Pavelius'' * '' Rytocephalus' ...

Terebellida
Terebellida make up an order of the Polychaeta class, commonly referred to as "bristle worms". Together with the Sabellida, the Spionida and some enigmatic families of unclear taxonomic relationship (e.g. the Saccocirridae), they make up the subclass Canalipalpata, one of the three main clades of polychaetes. Like most polychaetes, almost all members of the ''Terebellida'' are marine organisms. Most are small, sessile detritivores (deposit feeders) which live in small tubes they build from mud or similar substrate, or burrow in the sand. Their central nervous system displays characteristic apomorphies. Systematics There is little consensus on the number of families. Some treatments accept as little as five, while other authors list over a dozen. Here, the more inclusive view of the Terebellida is followed, based on a major review of polychaete systematics. Cladistic studies have hitherto only analyzed a rather small proportion of polychaetes; hence it may be that so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anders Johan Malmgren
Anders Johan Malmgren (21 November 1834 – 14 April 1897) was a Finnish zoologist and government official. Malmgren was a student in Helsinki in 1854, Master primus 1860, PhD 1864, Acting Commissioner of the fisheries in 1865, extraordinary professor of zoology at the University of Helsinki in 1869, Fishery Commissioner in 1877 and governor of the Oulu province in 1889. Malmgren undertook several scientific expeditions, especially in the northern latitudes, to the White Sea (1856) and to Spitsbergen and Finnmark as a participant in the first three Swedish expeditions (1861, 1864 and 1868). His most important scientific work involving the boreal region's fauna and flora; These include ''Kritisk öfversigt af Finlands fiskfauna'' (1863), ''Anteckningar om Spetsbergens fågelfauna'' (1863–64), ''Iakttagelser och anteckningar till Finnmarkens och Spetsbergens däggdjursfauna'' (1865) and ''Bidrag till Finnmarkens fiskfauna'' (1867). His most important works - the fruit of his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
