由于新的分子系统发育为以前的研究未预料到的自然类群提供了支持，鱼类分类与大多数其他分类类群一样，正在发生巨大的变化。然而，对鱼类学家在过去50年里用来定义其分类的主要标准的简要回顾表明，在使用明确的系统发育框架方面进展缓慢。相反，趋势是在不同程度上依赖于根深蒂固的解剖学概念和权威，经常将具有明确系统发育支持的分类群与任意分组混合在一起。鱼类学中经常用于鱼类分类的两个主要来源（JS Nelson的《世界鱼类》卷和W. Eschmeyer的《鱼类目录》）未能采用全球系统发育框架，尽管最近在解决鱼类生命之树方面取得了许多进展。第一个明确的硬骨鱼类系统发育分类于2013年发表，基于全面的分子系统发育（www.deepfin.org）。我们在此通过纳入最新的系统发育结果，更新了该分类的第一个版本。本文提出的最新分类是基于近2000种鱼类的分子和基因组数据推断的系统发育。与版本1的66个订单相比，该版本共识别了72个订单（和79个子订单）。系统发育确定了410科的归属，约占目前已知硬骨鱼514科的80%。然而，本研究中包括的30个percomorph科的顺序仍然不确定（Carangaria， Ovalentaria或Eupercaria系列中的intertae seis）。提出了支持分类决策的评论，并与他人提出的冲突分类群进行了比较。我们也强调的情况下，形态学支持存在的群体被分类。这个版本的硬骨鱼类系统发育分类有了很大的改进，提供了比以前版本更多的分类群的分辨率，基于更密集的采样系统发育树。与其他研究不同，本研究中提出的分类代表了鱼类生命之树的最新假设。本文的在线版本（doi:10.1186/s12862-017-0958-3）包含补充材料，可供授权用户使用。
Fish classifications, as those of most other taxonomic groups, are being transformed drastically as new molecular phylogenies provide support for natural groups that were unanticipated by previous studies. A brief review of the main criteria used by ichthyologists to define their classifications during the last 50 years, however, reveals slow progress towards using an explicit phylogenetic framework. Instead, the trend has been to rely, in varying degrees, on deep-rooted anatomical concepts and authority, often mixing taxa with explicit phylogenetic support with arbitrary groupings. Two leading sources in ichthyology frequently used for fish classifications (JS Nelson’s volumes of Fishes of the World and W. Eschmeyer’s Catalog of Fishes) fail to adopt a global phylogenetic framework despite much recent progress made towards the resolution of the fish Tree of Life. The first explicit phylogenetic classification of bony fishes was published in 2013, based on a comprehensive molecular phylogeny (www.deepfin.org). We here update the first version of that classification by incorporating the most recent phylogenetic results. The updated classification presented here is based on phylogenies inferred using molecular and genomic data for nearly 2000 fishes. A total of 72 orders (and 79 suborders) are recognized in this version, compared with 66 orders in version 1. The phylogeny resolves placement of 410 families, or ~80% of the total of 514 families of bony fishes currently recognized. The ordinal status of 30 percomorph families included in this study, however, remains uncertain (incertae sedis in the series Carangaria, Ovalentaria, or Eupercaria). Comments to support taxonomic decisions and comparisons with conflicting taxonomic groups proposed by others are presented. We also highlight cases were morphological support exist for the groups being classified. This version of the phylogenetic classification of bony fishes is substantially improved, providing resolution for more taxa than previous versions, based on more densely sampled phylogenetic trees. The classification presented in this study represents, unlike any other, the most up-to-date hypothesis of the Tree of Life of fishes. The online version of this article (doi:10.1186/s12862-017-0958-3) contains supplementary material, which is available to authorized users.
