A Shark's Navigational System

A shark's nose knows, but smell is only one of several keenly attuned senses that make sharks efficient predators, another is a “fantastically sensitive organ” called a lateral line, which runs the length of a shark's body that picks up vibrations in the water. “Inspired by odor, sharks also look for current,” Atema said. “The two together is what makes them so efficient.”

Sharks follow their noses to zero in on prey—but only one nostril at a time. When sharks catch a whiff of a potential meal, timing is everything: They will head in the direction of the nostril that caught the scent first—even when the other nostril detects higher concentrations of the odor.
