本文介紹的是狭义的辐鳍鱼类。關於广义的辐鳍鱼类——辐鳍鱼总纲(Actinopterygii),請見「輻鰭魚」。 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] 目录 1 分类 1.1 内部分类 1.2 种系发生学 2 参考文献 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] 种系发生学 依照2017年《硬骨鱼支序分类法》,本纲与其它硬骨鱼的演化关系如下[1][2]: 硬骨鱼高纲 Osteichthyes 辐鳍鱼总纲 Actinopterygii 辐鳍鱼纲 Actinopteri 新鳍亚纲 Neopterygii 真骨下纲 Teleostei 全骨下纲 Holostei 软质亚纲 Chondroste 腕鳍鱼纲 Cladistia 肉鳍鱼总纲 Sarcopterygii 肺鱼四足纲 Dipnotetrapodomorpha 肺鱼亚纲 Dipnomorpha 四足形亚纲 Tetrapodomorpha 腔棘魚綱 Coelacanthimorpha 軟骨魚綱 Chondrichthyes (外类群) 参考文献 ^ 1.0 1.1 1.2 1.3 1.4 1.5 Betancur-R, Ricardo; Wiley, Edward O.; Arratia, Gloria; Acero, Arturo; Bailly, Nicolas; Miya, Masaki; Lecointre, Guillaume; Ortí, Guillermo.

Actinopteri () is the sister group of Cladistia (bichirs) in the class Actinopterygii (ray-finned fish).

Dating back to the Permian period, the Actinopteri comprise the Chondrostei (sturgeons and paddlefish), the Holostei (bowfins and gars), and the teleosts; in other words, all extant ray-finned fish other than the bichirs.
