Collective behaviour defines the lives of many animal species on the Earth. Underwater
swarms span several orders of magnitude in size, from coral larvae and krill to tunas and …

Collective behavior is ubiquitous among fish, yet, its hows and whys are yet to be completely
elucidated. It is known that several environmental factors can dramatically influence …

Elucidating the hydrodynamics of fish swimming is critical to identifying the processes
underlying fish orientation and schooling. Due to their mathematical tractability, models …

Fish often swim in crystallized group formations (schooling) and orient themselves against
the incoming flow (rheotaxis). At the intersection of these two phenomena, we investigate the …

In this work, we study the polarization time series obtained from experimental observation of
a group of zebrafish (Danio rerio) confined in a circular tank. The complex dynamics of the …

When swimming animals form cohesive groups, they can reap several benefits. Our
understanding of collective animal motion has traditionally been driven by models based on …

Inspired by aquatic creatures such as squid, the novel propulsion method based on pulsed
jetting is a promising way to achieve high speed and high maneuverability. To study the …
