Fact of the Day: Dolphin Sleep

Being mammals, dolphins need air to breath. Which poses the question on how do dolphins sleep? Well the main way they do it is that they can shut down half of their brain while the other half goes on alert mode while slowly swimming. Then it will switch to the other side when the other half has gotten enough sleep.

  1. Amazing piece of information! Just some time ago, we had a big discussion about dophins here since it was big news that in Sweden somebody had eaten a ginnypig in a restaurant. The discussion in Helsinki was about what animals it's "okay" for humans to eat. It turned out that the only two animals that people would never even consider to eat in Helsinki would be the dog and the dolphin. In total, it was a very controversal discussion, and as usual, these discussions never lead anywhere.
    Thank you for leaving a kind comment on my blog!

    1. I think that's how whales do it. As they can breathe longer than a dolphin. Not sure on that one.

  7. That is very interesting! Love dolphins!
    They're kinda like cats who sleep 20 times a day, but never in a deep slumber, but only a light one...

  9. This sounds like a lot of the people I see in traffic. Shut off half of brain, coast into someone else's lane, almost kill everyone on the road. I'm sure it works out better for dolphins.
