11.09.2016 – Sleeping beauty

On our morning tour we probably saw a sunday morning “late riser” 🙂 At least with our human view. A Bottlenose dolphin floated motionless which appeared to us as a kind of “sleep”. Though dolphins in general do not sleep as most other mammals does. Because they need enough awareness for not to forget to breathe. It sound strange, but cetaceans really have to think about breathing. Not like in humans, where breathing is regulated automatically, even while sleeping or in a narcosis. To be able to rest enough anyway, in the dolphin brain always one hemisphere is active to coordinate breathing and to react to sudden threats (predators). Then, after a while the active hemisphere changes to the other one. So dolphins are resting in a kind of sleepy immobility. Overall they rest for about 8 hours, but not all at once.
