Excerpt:
Though we’re still not sure exactly why we and other animals snooze, we do know that sleep can look very different for creatures living underwater. Follow us down into the deep to discover how dozing in the ocean can be more bizarre than your wildest dreams.
This episode is part of (the Hakai Institute’s) series Ocean Wonders, (which dives) beneath the waves to explore the mysteries of life underwater..
