Phylogenetics of the marine sculpins (Teleostei: Cottidae) of the North American Pacific Coast

► Marine sculpins are the most species-rich radiation of fishes in the North Pacific. ► Most complete phylogenetic hypothesis yet generated for this assemblage. ► Maximum likelihood and Bayesian analyses produced similar tree topologies. ► Study suggests allopatric speciation important mode of speciation. ► In addition, repeated habitat shifts appear to have facilitated diversification.
