Comparison of fish responses to a virtual conspecific versus a virtual sphere.
(A) Probability density function (PDF) of the distance between the real fish and the virtual fish (red, mean 9.3 cm 7.0 SD) and between the real fish and a virtual sphere (black, mean 15.3 cm
7.2 SD). Vertical lines indicate the mean value of each distribution. (B) PDF of the relative alignment of the real fish with the virtual fish (red) and with the virtual sphere (black). (C) The maximum correlation with the virtual fish is
, reached at
+ nT, and
with the virtual sphere, reached at
, with T = 6.28 s,
