Photo by @mattiasklumofficial Such a privilege to have a totally relaxed female polar bear nursing her cubs right in front of me near the Nordenskiöld glacier, Svalbard. Go to @mattiasklumofficial to see the whole polar bear family! This female expressed particularly gentle behaviour while nursing and stretching her head back while softly groaning as if she really enjoyed the moment. Female polar bears nurse their cubs for approximately two years. In the first months, their milk is really rich in protein and comprised of over 30% fat content. The fat content decline over time as the cubs grow. I took this photograph right after the family had devoured a bearded seal. After a good meal some well deserved time to relax. One cub was already fast asleep. #svalbard #polar #polarbears #arctic #savingthearctic #climatechange #bwsp #conservation #expedition #mattiasklum #cubs #mom #predator @natgeo @natgeocreative @thephotosociety @mattiasklumcollection by natgeo http://bit.ly/1WuzfUc – Gatlinburg Garden Castle Rainbow Tower Library Imagination Station Temple Water Spirit Guardian Labyrinth Treasury Magic Healing
