Cubs are born in December. A litter of two is most common. It takes almost two months before they can walk or even see. This is a vulnerable time when cubs can end up being a meal for a male polar bear. In fact, a male will occasionally kill the mother and eat her too.
Cubs stay with their mothers until they are about two and a half years old.
Once they head off on their own, females begin the breeding cycle once again. QuickTime Movies Clicking on a movie title would normally play the movie selected. Unfortunately, the QuickTime movies contained on the CD-ROM are much too large for quick downloading over modems and are not available on the demonstration tour. Most of the movies contain narration describing an interesting aspect of the animal being displayed.
