• Stability and Breakdown of Collective Milling in Large Fish Schools

  ORAL

  Nov. 23, 2025, 10:34 AM – Nov. 23, 2025, 10:35 AM

  Publication: How do animal groups dynamically change their collective state? Here, we found that the cohesive collective patterns that are observed in a small number of individuals, whether polarized or rotationally ordered, tend to lose their stability with increasing number of individuals. Moreover, they form locally ordered pattern, which are dynamically interacting together, transferring information and energy to each other. These finds may allow animal groups to explore their environment efficiently.
