The strategy an animal uses to track a scent depends upon a number of factors, including the animal’s body shape and the amount of turbulence in the odor plume.

Scientists Are Trying to Figure Out How Animals Follow a Scent to Its Source

Uncovering the varied strategies that animals employ could help engineers develop robots that accomplish similar tasks
