Possum shrimp use their cave's special smell to trace their way home, study finds

Homing is an animal's ability to navigate towards an original location, such as a breeding spot or foraging territory. Salmon and racing pigeons are famous for homing, but similar behaviors occur in groups as diverse as bees, frogs, rats, and sea turtles. There, homing individuals are known or suspected to rely on landmarks, the Earth's magnetic field, or the sky's pattern of polarized light to find their way back.
