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 ...

Polychaete
Polychaeta () is a paraphyletic class of generally marine annelid worms, commonly called bristle worms or polychaetes (). Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class. Common representatives include the lugworm (''Arenicola marina'') and the sandworm or clam worm ''Alitta''. Polychaetes as a class are robust and widespread, with species that live in the coldest ocean temperatures of the abyssal plain, to forms which tolerate the extremely high temperatures near hydrothermal vents. Polychaetes occur throughout the Earth's oceans at all depths, from forms that live as plankton near the surface, to a 2- to 3-cm specimen (still unclassified) observed by the robot ocean probe ''Nereus'' at the bottom of the Challenger Deep, the deepest known spot in the Earth's oceans. Only 168 species (less than 2% of all polychaetes) are known from ...

Pectinariidae
Pectinariidae, or the trumpet worms or ice cream cone worms, are a family of marine polychaete worms that build tubes using grains of sand roughly resembling ice cream cones or trumpets. These structures can be up to long. The earliest pectinariid fossils are known from the Cretaceous. Ecology Pectinariids are sessile burrowing tube dwellers, which can be found in fine-grained sediment. They position the wider end of their tube downwards, and use their stout golden setae for digging while they use tentacles for sorting the particles which they ingest. Half of the particles which the worm digs through are excreted as pseudofaeces. Genera The systematics of the pectinariids have been the subject of some debate. Previously, only two genera have been recognized, but three subgenera have been elevated to full genera by some scholars.Hutchings, P., & Peart, R. (2002). A review of the genera of Pectinariidae (Polychaeta) together with a description of the Australian fauna. RECORDS ...
