How marine mammals survive underwater life – BBC wildlife
Posted on 31. Jul, 2010 by Eve in Parenting
Arctic seals have adapted so well to the sea that, even though still reliant on air for survival, they can be seen performing impressive displays underwater in the attempt to keep all the females occupied. Watch more ‘Seals – Invaders of the Sea?’ clips with BBC Worldwide here: www.youtube.com

That’s nuts, I thought it was the blood too. Evolution’s such a wonderful thing, I wonder what’s gunna happen to humans in the next 1000 years if we survive that long

very interesting. BBC nature shows are always the best. America cant make good interesting shows like this anymore. Most of the stuff on History and Natgeo is garbage. They still have some good stuff but mostly they are stupid documentaries about 2012 and disaster. But that show life after humans is pretty good.

The same technique of diving used by free divers but nowadays is not popular. They were blowing out air ay the start of the dive to have smaller volume. The bad thing with that technique was that there was a possibility of collapsing the pleura and lungs because of the low resist of the lung to the change of environmental pressure! This was happening at 20 – 30 m where the pressure is 3-4 atm, At the 400m of the depth the pressure is 41atm!!!!!
