The solenogastres do not have true ctenidia, although their gill-like structures resemble them.
The class is often combined with Solenogastres and termed Aplacophora, but some studies have cast doubt on the monophyly of this group.
A 2010 analysis recovered the traditional conchiferan and aculiferan groups, and showed molluscs were monophyletic, demonstrating that available data for solenogastres was contaminated.
The group comprises the two clades Solenogastres ( Neomeniomorpha ) and Caudofoveata ( Chaetodermomorpha ), which between them contain 28 families and about 320 species.
First, there are prevailing sequencing impediments in representatives of certain taxa, such as the mollusk classes Solenogastres and Tryblidia, selected bivalve taxa, and the enigmatic crustacean class Remipedia.
