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

It has long been proposed that flying and swimming animals could exploit neighbour-
induced flows. Despite this it is still not clear whether, and if so how, schooling fish …

Energy saving mechanisms are ubiquitous in nature. Aerodynamic and hydrodynamic
drafting, vortice uplift, Bernoulli suction, thermoregulatory coupling, path following, physical …

For animals, being a member of a group provides various advantages, such as reduced
vulnerability to predators, increased foraging opportunities and reduced energetic costs of …

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 …

Numerical simulations are employed to study hydrodynamic interactions between two-
dimensional fish-like bodies under a traveling wavy lateral motion in high-density diamond …

The question of how individuals in a population organize when living in groups arises for
systems as different as a swarm of microorganisms or a flock of seagulls. The different …

Wild zebrafish exhibit a wide range of behavior. We found abundant wild zebrafish in flowing
rivers and still water, in large, tightly-knit groups of hundreds of individuals, as well as in …

The coordinated motion by multiple swimmers is a fundamental component in fish schooling.
The flow field induced by the motion of each self-propelled swimmer implies non-linear …

We establish through numerical simulation conditions for optimal undulatory propulsion for a
single fish, and for a pair of hydrodynamically interacting fish, accounting for linear and …
