Forget Spidey Sense, Fish Sixth Sense Uses Flow Signals And Hydrodynamic Antennae

A team of scientists has identified how a "sixth sense" in fish allows them to detect flows of water, which helps resolve a long-standing mystery about how these aquatic creatures respond to their environment. The work in Physical Review Letters illustrates how sensory systems evolve in accordance with physical principles while also offering a framework for understanding how sensory networks are structured. read more
