A pregnant polar bear sticks out her black tongue as she senses her environment. All polar bears have black tongues. This female has a large wound from a walrsu encounter on her left hind leg. Lack of ice, leading to lack of prey forces the bears to attempt to kill unusally dangerous animals such as walrus taht can severely injure the bear.
