1. It had never occurred to me to wonder

how aquatic species without gills slept, either for a nap or for the night. Are they able to retain enough oxygen to be able to sleep more than say 20 minutes at a time? How on earth do they get enough rest? Do sleeping whales float near the surface, with their blowholes exposed or something? Are we sure that turtle isn't just dead?

3. Inquiring minds......I had the same thoughts so.........Google is your friend.

Sea turtles cannot breathe underwater, but they can hold their breath for long periods of time—between 4 to 7 hours when resting. While holding their breath, their heart rate slows significantly to conserve oxygen—up to nine minutes can pass between heartbeats.Dec 3, 2018

5. That looks very serene.

And holding one's breath for 4-7 hours!

8. As a matter of fact...

...we just happened to be in Maui last week when I noticed this post. We always try to photograph the Honu, (Green Turtles), when we visit. These are just a few of the hundreds of pics that we captured. Yes, they often pull themselves up onto the beaches or rocks to rest or sleep.





My wife shot this one.
