Polar Bear and Cubs International Polar Bear Day is celebrated annually on February 27 to raise awareness about polar bears and the threats they face. The date was chosen because it aligns with the denning period—when female polar bears give birth and care for their cubs in snow dens across the Arctic. This time is critical for cub survival, as they are born blind, deaf, and weighing less than a pound, relying entirely on their mother’s warmth and milk. Intersting Polar Bear Facts: Black skin, white fur: Despite their white appearance, polar bears have black skin that absorbs sunlight to keep them warm. Their fur is actually translucent, not white, and reflects light to create the illusion of whiteness. Exceptional swimmers: Polar bears can swim up to 100 kilometers (60 miles) without stopping. One recorded female swam 687 km (427 miles) over nine days in search of food. Powerful sense of smell: They can detect prey from 30 kilometers (20 miles) away, including seal breathing holes under ice and scent trails under snow. Long fasting periods: Female polar bears can go nearly eight months without eating while in dens, surviving on fat reserves built up during the hunting season. Hybrid bears: Rare grizzly-polar bear hybrids (called grolar or pizzly bears) have been documented, likely due to climate change forcing the species into closer contact. Conservation status: Polar bears are classified as vulnerable by the IUCN. With Arctic sea ice melting rapidly, their primary hunting ground is disappearing, threatening their long-term survival. Organizations like Polar Bears International use the day to promote research, education, and action—such as protecting denning habitats—to ensure polar bear populations endure for future generations.
