Fig 10. Spatial and velocity distribution of influential neighbors around a focal fish in groups of 5 individuals.

(A) Density map of influential neighbors’ location (blue) and their average relative velocity field (arrows) with respect to the focal fish (red arrow). (B) Average spatial distribution of influential neighbors in polar coordinates (red: highest frequency; dark blue: low frequency; white: frequency equals zero). (C) and (D): Distributions of the distance d_ij and the angle of exposure θ_ij respectively. Blue histograms: F_j is an influential neighbor of F_i; orange: F_j is a neighbor of F_i, not necessarily influencing F_i; dark pink: overlap between the two.
