Beluga whales, famous for their human-like facial expressions, don't like artificial materials such as neoprene diving suits, it seems.   So when Natalia Avseenko wanted to help two belugas adjust to humans in order to tame them for dolphinariums around the world, she got naked.

In sub-zero water temperatures.   Most people would die in 5 minutes or less in those temperatures but Avseenko credits yoga and meditation with her ability to last an incredible 10 minutes and 40 seconds.
