Polar Bear

Identification

The polar bear is the largest extant species of bear and land carnivore by body mass, with adult males weighing 300–800 kg (660–1,760 lb). Females are considerably smaller, making this species distinctly sexually dimorphic. Polar bears are easily recognised by their white or yellowish fur paired with black skin underneath, and they possess a thick layer of fat for insulation in Arctic conditions. More slender than their brown bear cousins, polar bears have a narrower skull, longer neck, and lower shoulder hump. Their teeth are sharper and more specialised for cutting meat, and their large paws are perfectly adapted for walking on ice and paddling through water.

Range & Habitat

Polar bears are native to the Arctic and nearby areas, where they occupy a unique ecological niche as both terrestrial and ice-living animals. Classified as marine mammals due to their dependence on marine ecosystems, they prefer the annual sea ice where they spend much of their time. During summer months when ice melts, they move onto land, where they may spend extended periods waiting for conditions to change. This dual existence—equally adapted to frozen seas and solid ground—defines their survival strategy in one of Earth's most extreme environments.

Behaviour & Diet

Polar bears are mostly carnivorous and have become specialised hunters of seals, particularly ringed seals. They employ sophisticated hunting techniques, stalking prey across ice or in water, and patiently waiting at breathing holes or ice edges for seals to surface. Once successful, they primarily feed on the energy-rich blubber rather than consuming the entire animal. Other prey includes walruses, beluga whales, and terrestrial animals when available.

These bears are typically solitary hunters, though they gather in groups when on land. During breeding season, males guard females and actively defend them from rivals. Females give birth to cubs in maternity dens during winter, and young cubs remain dependent on their mothers for up to two and a half years, learning essential survival skills in this harsh environment.

Best Time & Places to See It

The polar bear is classified as vulnerable by the International Union for Conservation of Nature, with an estimated population of 22,000 to 31,000 individuals across the Arctic. However, viewing opportunities are limited and challenging due to their remote habitat and the logistical difficulties of Arctic travel. The bears' distribution and accessibility vary seasonally with sea ice conditions, which are increasingly unpredictable due to climate change. Those seeking to observe polar bears should consult with Arctic wildlife specialists and tour operators experienced in extreme-environment expeditions.

Photography Tips

Photographing polar bears presents extreme challenges and requires specialised equipment designed for Arctic conditions. The white and yellowish fur can be difficult to expose correctly against snow and ice, necessitating careful metering and potentially deliberate overexposure to retain detail in the subject. The bears' large size and powerful build make for dramatic compositions, but safety distances must be maintained at all times. Long lenses are essential both for capturing detail and for maintaining safe distances from these apex predators. Given climate change impacts on sea ice, documenting polar bears has become increasingly important for conservation awareness.
