A Polar Bear Nose
 

is six times more senstive to smell than a hunting dog's nose.
Beluga whales are hunted by Polar bears.
When Beluga whales molt they sometime rub themselves against boat
hulls and props.
Not a worry to most here, but any of you who boat in the Arctic should
be aware of this.
To the Inuit the thick Beluga skin is called muktuk, and is important
to their diet because it contains as much vitamin-C as oranges.
Florida oranges.
Funny how everything ties back to Florida when you talk boats.
