With 92 species along the North American Pacific Coast, marine sculpins represent the most species-rich radiation of fishes in this region. I used the mitochondrial cytochrome b gene and the nuclear ribosomal S7 intron for 99 species (76 North American, 19 Asian, and four North Atlantic) to produce the most complete phylogenetic hypothesis yet generated for this assemblage. Maximum likelihood and Bayesian analyses produced highly similar tree topologies. While many previously proposed groupings based on morphology are recovered, the molecular data suggest that a number of genera are para- or polyphyletic. However, this analysis supports the monophyly of one large clade that is found exclusively along the North American Pacific Coast (Chitonotous-Ruscarius-Artedius-Orthonopius-Clinocottus-Leiocottus-Oligocottus). Some sibling species have disjunct ranges, suggesting allopatric speciation. However, many other sibling species have largely overlapping ranges, and repeated habitat shifts appear to have facilitated diversification.
沿北美太平洋海岸有 92 种，海洋雕刻鱼类是该地区鱼类中物种最丰富的辐射群。我使用线粒体细胞色素 b 基因和核核糖体 S7 内含子对 99 种（76 种北美，19 种亚洲，4 种北大西洋）进行了研究，生成了迄今为止针对该组合体的最完整的系统发育假说。最大似然法和贝叶斯分析产生了高度相似的树拓扑结构。虽然恢复了许多以前基于形态学提出的分组，但分子数据表明，有几个属是并系或多系的。然而，这项分析支持一个大型支系的单系性，该支系仅存在于北美太平洋海岸（Chitonotous-Ruscarius-Artedius-Orthonopius-Clinocottus-Leiocottus-Oligocottus）。一些近缘种的分布范围是间断的，这表明是异域物种形成。然而，许多其他近缘种的分布范围有很大的重叠，栖息地的反复变化似乎促进了多样化。
