Super Senses: How Sharks Hunt Down Prey

Elizabeth Howell, LiveScience contributor | April 02, 2014 05:00pm ET

It turns out that blindfolding a shark or plugging its nose isn't enough to deter it from going after prey. When a shark gets hungry, it will use all the senses it has available to hunt down something to eat, a new study reveals.

The goal of the study was to figure out how sharks use their different senses together, rather than isolating one sense at a time.Researchers examined three species of sharks — blacktip, bonnethead and nurse sharks — in an artificial flow channel inside the Mote Marine Laboratory in Sarasota, Fla.

"The biggest motivation with this multisensory approach was to try to understand what they're really doing in a natural environment with sensory cues," said Jayne Gardiner, a postdoctoral fellow at Mote who led the study.
