在数量上，无板类软体动物在软体动物中的重要性是次要的，与腹足类、双壳类甚至石鳖相比，它们仍然是一个有点模糊的类群。当涉及到命名，分类和分类时，正在进行的混乱，被称为无板纲与毛皮形亚纲和Neomeniomorpha，或者两个纲Solenogastres和Caudofoveata，在这个问题上也没有帮助。尽管如此，在过去的十年里，在无板动物的生物学、形态学、分类学以及目前的无板动物的发生学方面，已经取得了许多重要的成果。这些结果表明，Solenogastres和Caudofoveata之间的姐妹群关系，但也表明，有一些关键的差异，支持分为两个独立的类。在这里，目前的无板动物研究的现状进行了概述和重要的开放性问题进行了讨论，为今后的研究重点领域。
In numbers, the aplacophoran mollusks are of subordinate importance amongst the Mollusca and they remain a somewhat obscure group as compared to gastropods, bivalves, or even chitons. The ongoing confusion when it comes to naming, categorizing, and classifying what is known as either the class Aplacophora with subclasses Chaetodermomorpha and Neomeniomorpha, or the two classes Solenogastres and Caudofoveata, is not helpful in this matter, either. Nevertheless the last decade has brought a number of important results when it comes to aplacophoran biology, morphology, taxonomy, and currently also aplacophoran phylogeny. These results point to a sistergroup relationship between Solenogastres and Caudofoveata, but also show that there are a number of crucial differences that support a classification into two separate classes. Here, the current status of aplacophoran research is outlined and important open questions are discussed as focus areas for future studies.
