Chaetodermomorpha

	Chaetodermomorpha Caudofoveata is a small class within the phylum Mollusca, also known as Chaetodermomorpha. The class is often combined with Solenogastres and termed Aplacophora, but some studies have cast doubt on the monophyly of this group. Anatomy Caudofoveata are small (1–30 mm), mainly deep sea molluscs. They are worm-like, lacking shells or distinct muscular feet; they instead have scales and calcareous spines called sclerites, for movement. Ecology Caudofoveates live by burrowing through soft sediment, and feed by lying vertically in the sediment with just the mouthparts exposed and taking in passing organic detritus. During sexual reproduction, the female produces eggs which are fertilized and brooded, and then the larvae swim freely. Diet Caudofoveates feed on foraminifera. Taxonomy Caudofoveata comprises the following families and genera: * Chaetodermatidae ''Caudofoveatus'' '' Chaetoderma'' * Falcidentidae '' Chaetoderma'' ''Falcidens'' '' Furcillidens'' ...

picture info	Aplacophora Aplacophora is a presumably paraphyletic taxon. This is a class of small, deep-water, exclusively benthic, marine molluscs found in all oceans of the world. MolluscaBase eds. (2021). MolluscaBase. Aplacophora. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=411 on 2021-04-13 All known modern forms are shell-less: only some extinct primitive forms possessed valves. The group comprises the two clades Solenogastres (Neomeniomorpha) and Caudofoveata (Chaetodermomorpha), which between them contain 28 families and about 320 species. The aplacophorans are traditionally considered ancestral to the other mollusc classes. However, the relationship between the two aplacophoran groups and to the other molluscan classes and to each other is as yet unclear. Aplacophorans are cylindrical and worm-like in form, and most very small, being no longer than ; some species, however, can reach a length of . Habitat Caudofoveates generall ...

	Solenogastres The Solenogastres (less often referred to as Neomeniomorpha), common name the solenogasters, are one class of small, worm-like, shell-less molluscs (Aplacophora), the other class being the Caudofoveata ( Chaetodermomorpha). MolluscaBase eds. (2021). MolluscaBase. Solenogastres. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=2094 on 2021-04-14 Some recent literature, and recent molecular evidence, indicates that the Aplacophora may be polyphyletic, and therefore these taxonomists divide Solenogastres and Caudofoveata into separate classes. Morphology In contrast to all other molluscan classes, the Aplacophora have no shell, and are instead covered by aragonitic sclerites (calcareous spicules), which can be solid or hollow. These spicules can be arranged perpendicular to one another within the cuticle to form a skeleton, or can stick up to form a palisade, or can lie flat against the cuticle. 80% of solenogaster specie ...

	Prochaetodermatidae The Prochaetodermatidae are a family of small worm-shaped (<1 cm) chaetoderm mollusc s. The burrowing organisms lack a true foot; they have a large pair of jaws and a small radula , comprising a dozen rows of paired teeth. They are known from around the globe, except in polar region The polar regions, also called the frigid geographical zone, zones or polar zones, of Earth are the regions of the planet that surround its geographical poles (the North Pole, North and South Poles), lying within the polar cir ...

	Falcidens ''Falcidens'' is one of three genera within the family Chaetodermatida; its radula consists of a single row of teeth which are mineralized in crystalline hydroxyapatite (a most unusual mineral in organisms), and its teeth are not periodically shed and replaced like in other molluscs. '' For details of the radula, see Radula#In caudofoveates.'' It contains the following species: * '' Falcidens acutargatus'' Salvini-Plawen, 1992 * '' Falcidens aequabilis'' Salvini-Plawen, 1972 * '' Falcidens caudatus'' Heath, 1918) * '' Falcidens chiastos'' Scheltema, 1989 * '' Falcidens crossotus'' Salvini-Plawen, 1968 * '' Falcidens gutturosus'' Kowalewsky, 1901) * '' Falcidens halanychi'' Schander, Scheltema & Ivanov, 2006 * '' Falcidens hartmanae'' Schwabl, 1961) * '' Falcidens hoffmanni'' Stork, 1939) * '' Falcidens indicus'' Stork, 1941) * '' Falcidens ingolfensis'' Salvini-Plawen, 1971 * '' Falcidens limifossorides'' Salvini-Plawen, 1986 * '' Falcidens liosqueameus'' Salvini-Plawen, ...
