Quinn: "Mom, if dolphins breathe air instead of water, why don't they drown when they sleep?"
I just Googled dolphin sleep, because I couldn't stand not knowing the answer. How DO they sleep? Listen to this...
Dolphins have to be conscious to breathe. This means that they cannot go into a full deep sleep, because then they would suffocate. Dolphins have "solved" that by letting one half of their brain sleep at a time. This has been determined by doing EEG studies on dolphins. Dolphins sleep about 8 hours day in this fashion.
No WAY!
