Dolphins, much like human swimmers have to consciously think about breathing as breathing can only occur at or above the surface.
Unlike human swimmers, dolphins remain in the water indefinitely and have to sleep in it. To manage both surface breathing and resting they “sleep” one half of their brain and close one eye at a time.
It is common for dolphins to rest in pairs, keeping an eye on their partner (inner eyes open).
