Phenotypic group structure reveals the role of hidden internal states in structuring the behavioral variability among fish exposed to the same sensory context. (A1) Transition matrix space color-coded according to the 7 phenotypic groups, with naive fish hunting for paramecia highlighted. (A2) Fraction of bouts with high eye convergence for naive fish hunting paramecia according to the phenotypic group reveals that fish in and spent less time with eyes converged, indicating lower rate of hunting than fish in other groups. (B1) Transition matrix space color-coded according to the seven phenotypic groups, with fish exploring in the light that were previously raised with rotifers highlighted. (B2) Fraction of bouts with eye convergence across fish in the light raised in different conditions across phenotypic groups uncovers that fish in and show very little eye convergence rates, while fish in exhibit higher eye convergence, indicating that they attempt hunting more frequently. These differences indicate that phenotypic groups reflect hidden internal states impacting behavior. We estimate the eye convergence rates per fish, and show the phenotypic groups that have more than one fish with bootstrapped 95% CI obtained across fish.
