The paper challenges the hypothesis of multiple freshwater invasions in otophysan fish by showing that a single invasion is more likely, based on phylogenetic and biogeographic analyses.

The paper investigates marine-to-freshwater fish transitions in Sahul rivers, finding that diversification success depends on paleoenvironmental dynamics rather than just ecological opportunity.

The paper shows that extreme snout elongation in deep-sea fishes evolved independently but along constrained trajectories due to phenotypic integration and functional innovation.

The paper analyzes skull diversification in eupercarian fishes, showing habitat and trophic ecology independently shape skull shape, with rapid evolution in certain clades and convergence in freshwater lineages.

This study uses phylogenomic and phenotypic data to show that deep-sea anglerfishes have greater diversity and faster diversification rates than shallow-water relatives, challenging expectations about habitat constraints.
