Cyclomenia is a genus of cavibelonian solenogaster, a kind of shell-less, worm-like mollusk. [2]
Aplacophora is a monophyletic group of small, deep-water, exclusively benthic, marine molluscs found in all oceans of the world. 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.
The Solenogastres, common name the solenogasters, are one subclass of small, worm-like, shell-less molluscs (Aplacophora), the other subclass being the Caudofoveata (Chaetodermomorpha).
The Neomeniamorpha are one of the four taxonomic orders of solenogasters, shell-less, worm-like, marine mollusks.
The Pholidoskepia are one of the four orders of solenogaster.
The Sterrofustia are one of the four orders of solenogaster.
The Cavibelonia are one of the four orders of solenogaster, a kind of shell-less, worm-like mollusk.
Sandalomenia is a genus of solenogaster, and the only genus in its family.
Macellomenia is a genus of solenogaster, and the only genus in its family.
Heteroherpia is a genus of solenogaster, and the only genus in the Heteroherpiidae family.
Imeroherpiidae is a family of solenogaster, comprising the sole genus Imeroherpia.
Wirenia is a genus of pholidoskepian solenogasters, shell-less, worm-like, marine mollusks.
Driomenia is a genus of cavibelonian solenogasters, a kind of shell-less, worm-like mollusk.
Rhopalomenia is a genus of cavibelonian solenogasters, shell-less, worm-like, marine mollusks.
Entonomenia is a genus of cavibelonian solenogasters, shell-less, worm-like mollusks.
Epimenia is a genus of cavibelonian solenogasters, a kind of shell-less, worm-like mollusks. During the development of species in this genus, the sclerites start out as solid tips, then a hollow stalk develops that is subsequently infilled.
Epiherpia is a genus of cavibelonian solenogasters, shell-less, worm-like mollusks. It contains only one known species, Epiherpia vixinsignis, which was originally classified as a species of Epimenia, with doubt, based on a single immature specimen.
Sputoherpia is a genus of cavibelonian solenogaster, shell-less, worm-like, marine mollusks.
Pruvotinidae is a diverse taxonomic family of cavibelonian solenogasters, shell-less, worm-like marine mollusks.
Sialoherpia is a genus of cavibelonian solenogasters, shell-less, worm-like, marine mollusks.
Labidoherpia is a genus of cavibelonian solenogasters, shell-less, worm-like, marinemollusks.
