The literal translation of the Latin name for polar bears is "sea bear". Whoever gave them their scientific name obviously spent time observing them. They aren't just capable swimmers. They are true marine mammals and love the water. When it was really windy and they all seemed to prefer staying in the water(when they weren't sleeping behind a log). Anyway, here are a couple of photos.
Best viewed in the light box.
1) Here's a momma bear swimming with the kids. This was a huge sow that I dubbed "Bertha" for a popular song of my youth.
2) Bertha
3) They frequently dive and swim underwater. When they come up of course they shake the water off their heads. So there were ample opportunities for shots of them shaking. But with so much ice/snow around there weren't many opportunities with contrasting BG.
4) They loved wrestling in the water.
5) I posted this one in another thread but it's my favorite water shot so here it is again.
6) OK they're not swimming in this one but I thought it was cool. Beach front living.
