Below is a video I created of the polar bears of Kaktovik, Alaska….
Two polar bear cubs get very physical with each other. The two played for over an hour, the smaller cub instigating another round of play fighting each time the duo broke off for a breather. Play fighting may look like fun but it is in effect a useful tool to train muscles and young cubs on how to defend themselves when they become adults.
Currently polar bears (Ursus maritimus) are listed by the IUCN as Vulnerable. Threats to their existence include hunting and loss of habitat.
