The worst of all...Human Garbage! Hunting Polar Bears are amazing hunters. They will wait for a long time as long as they get there food. Here is how they get some of there food: they wait for the seals to come to the surface , then it pulls the seal on to land, and kills it. After it kills the seal it will start eating it. Polar Bears are like stalkers because they will watch there prey until there is a good spot to atack. Polar Bears somtimes hunts while swimming. http://static.ddmcdn.com/gif/polar-bear-3.jpg Behavior Zoologists say that a Polar Bears behavior is unpredictible.They have been able to predict some things, however. They say Polar Bears are usualy by themselves(unless it is mating season.). They are mostly active at night(nocturnal). Polar Bears are advanced swimmers. They have a strong smell to them to basically say 'Back off'. If Polar Bears are not sleeping they are hunting. http://www.ansnuclearcafe.org/wp-content/uploads/2011/07/polar-bear1.jpg Mating Mating happens from May to April.

together for about a week. Polar Bears
have the slowest reprduction rate of all
mamals. Reproduction and Family Birth Polar Bears have 1-4 cubs. 2 cubs is the most likely number of cubs they have. Cubs are usualy born from November- January. The mothers are hibernating while they give birth. Mothers can give birth to five litters in a life time. http://www.buncee.com/files/uploads/image/baby-polar-bear-wallpapers-6.jpg Pregnancy The mothers are pregnant for about 8 months.

Polar Bear mothers are pregnant they build a
den(which is probaly made of snow drifts,snow
wood,etc.). Polar Bears can start geting pregnant
at age 4. http://www.frontiersnorth.com/blog/wp-content/uploads/2010/04/polar-bear-tripod.jpg http://blogs.sandiegozoo.org/wp-content/uploads/2011/09/L8J8348.jpg Polar Bear Cubs When the cubs are born they are born blind.
The cubs are very dependent on there mother(because they are blind.) if there mother was to die, they would die to.They will stay in there den utill spring. Untill they can hunt they eat breast milk from there mother, and there mother brings them seal meat. When they are finnaly ready the mother will teach them to hunt. They will stay with there mother untill they are about 2 1/2 years old. http://www.bearlife.org/images/polar-bear-cubs.jpg http://naturescrusaders.files.wordpress.com/2009/04/polar-bear-coaxing-baby.jpg Endangered, How You Can Help Polar Bears went on the endangered list in 2008.
