The dolphins brain
May 4, 2011 by Victoria Rowe No Comment
From the whale companies: Dolphins can move their eyes independently from each other, enabling them to focus on two different objects at one time.
They can stay up to 15 minutes under water although they usually stay only a few minutes diving.
They sleep by resting one half of their brain at a time so that one eye is always open. This allows them to rise to the surface to breathe and to protect themselves from predators
