What animal sleeps with one eye open?

What animal sleeps with one eye open?

A: For dolphins, this is an easy task. They can turn off half their brain and close one eye, allowing them to be partly asleep and awake at the same time. According to an article in the Scientific American , dolphins sleep this way so they can be ready to protect themselves from predators and swim to the surface for air. Source: sleepfoundation.org
