Fauveliopsidae
Fauveliopsidae is a family of polychaetes belonging to the order Terebellida. The genus name honours Pierre Fauvel. It is a small family, containing only three genera and about twenty species. They are benthic animals, noted for their habit of sometimes living in the empty shells of dead gastropods, scaphopods, and foraminiferans Foraminifera ( ; Latin for "hole bearers"; informally called "forams") are single-celled organisms, members of a phylum or class of Rhizarian protists characterized by streaming granular ectoplasm for catching food and other uses; and commonly ....

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 fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terebellida
Terebellida make up an Order (biology), order of the Polychaete, Polychaeta class (biology), class, commonly referred to as "bristle worms". Together with the Sabellida, the Spionida and Incertae sedis, some enigmatic families of unclear Taxonomy (biology), taxonomic relationship (e.g. the Saccocirridae), they make up the Subclass (biology), subclass Canalipalpata, one of the three main clades of polychaetes. Like most polychaetes, almost all members of the ''Terebellida'' are Marine (ocean), marine organisms. Most are small, Sessility (zoology), sessile detritivores (deposit feeders) which Tube worm (body plan), live in small tubes they build from mud or similar substrate, or burrow in the sand. Their central nervous system displays characteristic Synapomorphy, apomorphies. Systematics There is little consensus on the number of Family (biology), families. Some treatments accept as little as five, while other authors list over a dozen. Here, the more inclusive view of the Tereb ...

Pierre Fauvel
Pierre Louis André Fauvel (8 October 1866 in Cherbourg – 12 September 1958 in Angers) was a French zoologist, who specialized in the study of ''polychaetes''. He worked as a préparateur of zoology at the faculty of sciences in Caen, and in 1897 received his doctorate at the Sorbonne with a thesis on ''Ampharetidae''. During the same year, he became a professor of zoology at the Université Catholique de l'Ouest in Angers, where he remained until his retirement in 1951.Fauvel, Pierre Enciclopedia Italiana The polychaete family '''' bears his name, as does the genus ''Fauveliopsis''.

Benthic Zone
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from the Ancient Greek word (), meaning "the depths". Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and Fungus, fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here, known as bottom dwellers, generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at t ...

Gastropoda
Gastropods (), commonly known as slugs and snails, belong to a large Taxonomy (biology), taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, freshwater, and from the land. There are many thousands of species of sea snails and sea slug, slugs, as well as freshwater snails, freshwater limpets, land snails and slugs. The class Gastropoda is a diverse and highly successful class of mollusks within the phylum Mollusca. It contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Furongian, Late Cambrian. , 721 family (taxonomy), families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently neontology, extant living fossil, with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scaphopods
Scaphopoda (plural scaphopods , from Ancient Greek σκᾰ́φης ''skáphē'' "boat" and πούς ''poús'' "foot"), whose members are also known as tusk shells or tooth shells, are a class of shelled marine invertebrates belonging to the phylum Mollusca with worldwide distribution and are the only class of exclusively infaunal marine molluscs. Shells of species within this class range in length (with ''Fissidentalium metivieri'' as the longest). Members of the order Dentaliida tend to be larger than those of the order Gadilida. These molluscs live in soft substrates offshore (usually not intertidally). Because of this subtidal habitat and the small size of most species, many beachcombers are unfamiliar with them; their shells are not as common or as easily visible in the beach drift as the shells of sea snails and clams. Molecular data suggest that the scaphopods are a sister group to the cephalopods, although higher-level molluscan phylogeny remains unresolved. Cla ...

Foraminifera Test
Foraminiferal tests are the Test (biology), tests (or shells) of Foraminifera. Foraminifera (''forams'' for short) are single-celled predatory protists, mostly marine, and usually protected with shells. These shells, often called Test (biology), tests, can be single-chambered or have multiple interconnected chambers; the cellular machinery is contained within the shell. So important is the test to the biology of foraminifera that it provides the scientific name of the group—''foraminifera'', Latin for "hole bearers", referring to the pores connecting chambers of the shell in the multi-chambered species. Foraminiferal tests are usually made of calcite, a form of calcium carbonate (), but are sometimes made of aragonite, Agglutination (biology), agglutinated sediment particles, chitin, or (rarely) of Silicon dioxide, silica. Other foraminifera lack tests altogether. Over 50,000 species are recognized, both living (6,700 - 10,000)Ald, S.M. ''et al.'' (2007Diversity, Nomenclature, ...
