the Lounge.  Even though  she did  not hear much of  the lecture,

                   she was able to get the answers to some questions we had posed
                   earlier about polar bear, seal & walrus sleep and about their need

                   for fresh water.

                          Where do Polar Bears and Walrus get fresh water to drink?

                   The fresh water question was the easier of the two. None of them
                   requirement  fresh  water  in  their  diets  because  they  create  it  in
                   their own fat and then can metabolize it as the fat is burned for

                   energy.  So  when  any  of  these  creatures  is  observed  licking  or
                   chewing on ice, it probably is just curiosity or the animal may be

                   starving  so  that  there  is  insufficient  fat  in  its  body.  The  sleep
                   question had a two-fold answer: Polar bears and to a lesser extent

                   walrus do indeed sleep and for fairly lengthy periods of time. Both
                   creatures  are  at  the  top  of  the  food  chain  and  do  not  need  to

                   exercise the constant vigilance of smaller prey animals. Therefore,
                   polar bears often sleep after eating right next to their kill up to
                   hours at a time. Walrus often sleep in their “huddles’’ when there

                   are no young among them. Even the walrus is wary when calves
                   are present. The seals, on the other hand, must always sleep with

                   one  eye  open  since  they  are  quite  vulnerable  to  the  bears  and
                   walrus. They usually doze no more than a couple of minutes at a

                   time.


                   After our midday “optional” feeding time (Ralph’s little joke), we
                   were  told  that  we  were  cruising  in  more  open  waters  between
                   Berentsoya and the island group of Kong Karls  Land, looking for

                   clearer visibility and for ice bears. We went in and out of fog but
                   saw some phantasmal ice floes, bergie bits, and sea ice. We visited

                   the  bridge  to  learn  a  little  about  navigation  and  how  the
                   equipment works. We visited the Gift Shop  and got a  couple of

                   souvenirs.
