Why does a dolphin sleep with one eye open?🐬
Dolphins are able to sleep by alternately turning off one of the hemispheres. The second is awake at this moment. One eye is open in order to track changes in the environment. If the right hemisphere is asleep and the left hemisphere is awake, then the right eye is open. And vice versa.
