During development, many Solenogastres are covered by a spiny scleritome comprising spines or scale-like plates. This has been likened to the halwaxiid scleritome. [5]Sclerites of Epimenia start out solid before developing a hollow stem that subsequently solidifies. [6]Solenogastres can be found in a diverse range of habitats across the world, from the coast to the deep ocean.

solenogaster, small, wormlike, marine mollusk of the class Aplacophora (subclass Neomeniomorpha). Unlike most other mollusks, solenogasters have no shell. The body is covered instead by a cuticle containing many calcareous spicules. Most solenogasters are 2.5 cm (1 inch) or less in length. The largest is 30 cm long.

A head shield, like among the caudofoveatans, is absent, but solenogasters instead have a head groove with numerous sense cells. The group's scientific name, Solenogastres, literally means "animals with a furrowed belly", also a hint towards the characteristic ventral furrow of …

Fewer than 100 species are known, and they feed mainly on microorganisms and detritus. The free-living, more or less uniformly worm-like, elongate and laterally compressed Solenogastres (Figure 1b, c), with over 200 recognized species, are 1–300 mm in length.

Working with others to conserve, protect and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people.

The Solenogastres (less often referred to as Neomeniomorpha), common name the solenogasters, are one subclass of small, worm-like, shell-less molluscs (Aplacophora), the other subclass being the Caudofoveata (Chaetodermomorpha).

Solenogastres (Aplacophora) is a small clade of marine, shell-less worm-molluscs with close to 300 valid species. Their distribution ranges across all oceans, and whereas the vast majority of species has been collected and described from the continental shelf and slope, only few species are known from depths below 4,000 m.

2019年5月8日 · Recent molecular phylogenetic investigations strongly supported the placement of the shell-less, worm-shaped aplacophoran molluscs (Solenogastres and Caudofoveata) and chitons (Polyplacophora) in a clade called Aculifera, which is the sister taxon of all other molluscs.

The Solenogastres are mostly small (less than 5 cm long] worm-like mollusks that live symbiotically (or feed upon) cnidarians. As with the Caudofoveata, many of the typical molluscan characters are absent. They have no shell, eyes, or tentacles.

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).
