Neanthes Fucata
''Neanthes fucata'' is a species of marine polychaete worm in the family Nereididae. It lives in association with a hermit crab such as ''Pagurus bernhardus''. It occurs in the northeastern Atlantic Ocean, the North Sea and the Mediterranean Sea. Taxonomy This worm was first described in 1822 by the French zoologist Marie Jules César Savigny who gave it the name ''Nereis fucata'', however it was later transferred to the genus '' Neanthes'', making it ''Neanthes fucata''. Description The body of this segmented worm is long, slender and tapering, with a smooth cuticle. The prostomium bears a pair of antennae, a pair of palps and two pairs of eyes. The first body segment is twice as long as the rest and bears the pharynx and four pairs of tentacular cirri. Segments two and three have uniramous parapodia (unbranched lateral lobes bearing bristles) while the remaining segments bear biramous (two-lobed) parapodia. This worm is yellowish, with longitudinal stripes in red and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hjalmar Kinberg
Johan Gustaf Hjalmar Kinberg (13 May 1820 – 29 August 1908) was a Swedish zoologist, physician and veterinarian who was born in Grönby, near Trelleborg, Skåne County and who died in St. Matthew's Parish, Stockholm. Family Hjalmar Kinberg's father was a rural dean, as was his grandfather, . His mother, Margareta Lovisa Schlyter, was the sister of Professor Carl Johan Schlyter, a noted Swedish lawyer and academic. Kinberg married twice, first, in 1854, to Helena Stockenberg (1831–1858). After the death of his first wife, he married again in 1859 to Aurore Hammarskjöld. He had two children: Arvid Gustaf Kinberg who was born in 1860 and Gottfrid Hilding Kinberg who was born in 1874. He is the great-great-grandfather of Anna Kinberg Batra, a Swedish politician who was Leader of the Moderate Party and Leader of the Opposition in Sweden. Career Kinberg enrolled at the University of Lund in 1838 and graduated with a degree in natural sciences in 1844, then a Master of Philosoph ...

Polychaetes
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 fresh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nereididae
Nereididae (formerly spelled Nereidae) are a family of polychaete worms. It contains about 500 – mostly marine – species grouped into 42 genera. They may be commonly called ragworms or clam worms. Characteristics The prostomium of Nereididae bears a pair of palps that are differentiated into two units, the proximal unit is much larger than the distal unit. Parapodia are mostly biramous (only the first two pairs are uniramous). Peristomium fused with the first body segment, with usually two pairs of tentacular cirri. The first body segment with 1-2 pairs tentacular cirri without aciculae. Compound setae present. Notopodia are distinct (rarely reduced), usually with more flattened lobes, notosetae compound falcigers and/or spinigers (rarely notosetae absent). They have two prostomial antennae (absent in ''Micronereis''). Their pharynx, when everted, clearly consists of two portions, with a pair of strong jaws on the distal portion and usually with conical teeth on ...

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...

Neanthes Arenaceodentata
''Neanthes arenaceodentata'' is a species of marine polychaete worm in the family Nereididae. It occurs in shallow waters in the tropical Atlantic and Pacific Oceans. It has been used in the laboratory in testing the toxicity of marine sediments. Taxonomy This worm was first described in 1903 by the American naturalist Justin P. Moore who gave it the name ''Nereis arenaceodentata''. At one time referred to as ''Nereis (Neanthes) arenaceodentata'', '' Neanthes'' was later raised to full genus level, making this worm ''Neanthes arenaceodentata''. Research suggests that the populations to the east and west of North America, which are reproductively isolated, may be two separate species. The genus name is from the Greek Νεάνθης "new-blooming", while the specific name is from Latin ''arēnāceō'' + ''dentāta'', "sandy-toothed." Distribution and habitat ''Neanthes arenaceodentata'' is found in the tropical Pacific and Atlantic Oceans and the Caribbean Sea. It occurs in the s ...
