From: Beyond planar: fish schools adopt ladder formations in 3D
Fish schools are three-dimensional and transient. Time series of the (A) average fish speed with respect to the chamber, and (B) height of the school. The inset in A shows the variation over a 30-second window. Black lines represent moving averages and the gray regions represent standard deviations across 1-min-long moving windows. The transient period is marked in blue. Autocorrelation functions for (C) individual fish coordinates and (D) school volume.
