We report on the dynamics of collective alignment in groups of the cichlid fish Etroplus
suratensis. Focusing on small-to intermediate-sized groups (10≲ N≲ 100), we demonstrate …

A ubiquitous type of collective behavior and decision-making is the coordinated motion of
bird flocks, fish schools, and human crowds. Collective decisions to move in the same …

Classical models of collective behavior often take a “bird's-eye perspective,” assuming that
individuals have access to social information that is not directly available (eg, the behavior of …

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 …

A wide range of measurements can be made on the collective motion of groups, and the
movement of individuals within them. These include, but are not limited to: group size …

A variety of simple models has been proposed to understand the collective motion of
animals. These models can be insightful but may lack important elements necessary to …

Complex schooling behaviors result from local interactions among individuals. Yet, how
sensory signals from neighbors are analyzed in the visuomotor stream of animals is poorly …

The" selfish herd" hypothesis 1 provides a potential mechanism to explain a ubiquitous
phenomenon in nature: that of non-kin aggregations. Individuals in selfish herds are thought …

Many animals, including humans, have evolved to live and move in groups. In humans,
disrupted social interactions are a fundamental feature of many psychiatric disorders …

Zebrafish constitute a convenient laboratory–based biological system for studying collective
behavior. It is possible to interpret a group of zebrafish as a system of interacting agents and …
