亚纲



  • 软质亚纲 Chondrostei


  • 新鳍亚纲 Neopterygii




辐鳍鱼纲（學名：Actinopteri）又名条鳍鱼纲，是动物界脊索动物门的一纲，也是辐鳍鱼总纲的两个演化支之一，包含了所有与新鳍亚纲关系较近、离多鳍鱼目较远的辐鳍鱼。[1][2]



分类


在不同的分类系统中，这一演化支的分类层级有时也称为“辐鳍鱼下纲”或“辐鳍鱼亚纲”不等。基本上，本纲包含了绝大多数的现存辐鳍鱼，而腕鳍鱼纲（现仅剩多鳍鱼目）是本纲的姐妹群。[1][2]



内部分类


本纲可分成两个亚纲，如下[1][2]：




  • 软质亚纲 Chondrostei

    • 鲟形目 Acipenseriformes



  • 新鳍亚纲 Neopterygii


    • 全骨下纲 Holostei


    • 真骨下纲 Teleostei




其中软质亚纲仅有鲟形目，而不再包含多鳍鱼目。[1][2]
