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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonelliidae
Bonelliidae is a family of marine worms (Class Echiura, phylum Annelida) noted for being sexually dimorphic, with males being tiny in comparison with the females. They occupy burrows in the seabed in many parts of the world's oceans, often at great depths. Characteristics Members of the class Echiura are plump, unsegmented worms, commonly known as spoonworms. The mouth is at the anterior end of the trunk and a flattened proboscis extends forward in front of the mouth. The ventral side of the proboscis has a ciliated channel along which food particles and mucus are moved towards the mouth. Close behind the mouth are two hooked chaetae and one or two nephridial pores. The gut is much longer than the body and is folded and coiled inside the coelom (body cavity). The anus is at the posterior end of the body and two anal vesicles with ciliated funnels open into the cloaca. In the family Bonelliidae, the females are very much larger than the dwarf males, and in most, if not all, inst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Bonellia Viridis
''Bonellia viridis'', the green spoonworm, is a marine worm (class Polychaeta , phylum Annelida) noted for displaying exceptional sexual dimorphism and for the biocidal properties of a pigment in its skin.Murina, G. (2008). Bonellia viridis Rolando, 1821. In: Read, G.; Fauchald, K. (Ed.) (2016). World Polychaeta database. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=110363 on 2016-05-28 Distribution The species is wide-ranging, found in the north-eastern Atlantic Ocean and the Mediterranean Sea. Description The pale- to dark-green female, with a 15 cm-long, round or sausage-shaped body, lives on the sea-floor at a depth of 10 to 100 metres, concealed by burrowing in gravel or hiding in rock crevasses or burrows abandoned by other animals. It has two anchoring hooks underneath its body and an extensible feeding proboscis up to 10 times its body-length. It is mainly a detritivore, feeding also on small animals. ...
