So incredible; so many mysteries still out there. Thanks for sharing.

quick glance at this topic header and I read it as 1.8meters.  Meh, i thougth no big deal 
1.8 mi = 9504 feet = 288 atmosphere's worth of pressure = a blown ear drum (or at least a splitting headache)

amazing!!

Very cool, thanks for sharing

They go down and stay down to chow down on the giant squids down there.

That's pretty amazing. Kind of like Fuzz!
