A celebrated and controversial hypothesis suggests that some biological systems—parts,
aspects, or groups of them—may extract important functional benefits from operating at the …

Moving animal groups display remarkable feats of coordination. This coordination is largely
achieved when individuals adjust their movement in response to their neighbours' …

Many fish species gather by the thousands and swim in harmony with seemingly no effort.
Large schools display a range of impressive collective behaviors, from simple shoaling to …

Fish schooling is often modeled with self-propelled particles subject to phenomenological
behavioral rules. Although fish are known to sense and exploit flow features, these models …

Recent work suggests that nonreciprocal interactions are universally present in living
systems and constitute an important part of active matter. These interactions, that are in …

Collective motion is ubiquitous in nature; groups of animals, such as fish, birds, and
ungulates appear to move as a whole, exhibiting a rich behavioral repertoire that ranges …

The development of tracking methods for automatically quantifying individual behavior and
social interactions in animal groups has open up new perspectives for building quantitative …

Bird flocks under predation demonstrate complex patterns of collective escape. These
patterns may emerge by self-organization from local interactions among group-members …

Collective behavior affords several advantages to fish in avoiding predators, foraging,
mating, and swimming. Although fish schools have been traditionally considered egalitarian …

Animal groups vary in their collective order (or state), forming disordered swarms to highly
polarized groups. One explanation for this variation is that individuals face differential …
