The ultimate power nap: Researchers use 'Fitbits' to track elephant sleep in the wild

Behavioral studies of elephant sleep in zoos record that they sleep around four hours per day and can sleep standing up or lying down — but how much do they sleep and how do they sleep in their natural environment?
