Did You Know?

Dolphins have to be conscious to breathe, this means that they cannot sleep like you and I do in a deep sleep as they would suffocate. To sleep dolphins sleep half of their brain at a time, we often see the dolphins snoozing on the surface of the water with their blowholes exposed, however it depends on the individual dolphins as to how they sleep. Some choose to swim slowly and surface occassionally for air or rest on the bottom in shallow water and swim to the surface every now and then to breathe or as we most commonly see resting on the surface.
