The Solenogastres (less often referred to as Neomeniomorpha), common name solenogasters, are a subclass of worm-like, small, shell-less molluscs (Aplacophora), the other subclass being the Caudofoveata (Chaetodermomorpha). 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 one another within the cuticle to form a skeleton; or can stick up to form a pallisade; or can lay flat against the cuticle.
