It’s long been known that fish swim in schools to protect themselves from predators, but could there be another reason? 

This week on the podcast, Shini Somara talks to Iain Couzin, professor of biodiversity and collective behavior at the University of Konstanz. His team has been placing robotic fish among schools to study the animals’ energy consumption. Couzin explains what we can learn from this study and why it could have real-world benefits for humans.
