The paper shows that behavioral differences in genetically identical fish can be transmitted across generations without genetic or environmental influences.

The paper tracks early-life activity in genetically identical fish to show it predicts lifespan variation, finding a U-shaped relationship between activity levels and longevity.

The paper shows larger fish shoals in the wild better detect predator attacks while maintaining constant false alarms and faster decision times.

The paper tests for paternal effects in a gynogenetic fish species and finds no evidence of paternal influence on offspring or brood size.

The paper studies how juvenile Arapaima gigas synchronize air-breathing behavior in groups despite individual differences, showing that assortative interaction rules enable collective synchronization.

The paper investigates collective escape patterns in sardines under predator attack, showing fountain effects arise from optimal escape rules and predator strategies.

This study compares social dynamics between cave and surface Atlantic mollies under different densities, finding surface mollies maintain social interactions better at low density.
