This study applies standardized cognitive testing to teleost fishes, revealing species-level variation in inhibitory control with weak phylogenetic signal and significant within-species differences.

The paper shows that loser effects, not winner effects, determine social dominance in female-to-male sex-changing fish, influencing sexual transformation through social hierarchy dynamics.

This study examines social hierarchy formation in sex-changing fish, finding that dominance is size-based and disruption leads to rapid behavioral and neural changes.
