Visitors to Aalborg Zoo, in Denmark, have been enjoying the antics of two adorable Polar Bear sisters.
The female cubs were born November 26 to mom, Malik, and the trio emerged from their birthing den in late February.
The Polar Bear (Ursus maritimus) is a carnivorous bear that is native to the circumpolar north including the United States (Alaska), Canada, Russia, Norway and Denmark (Greenland).
Polar Bears generally have their first set of cubs between the ages of four and eight years. Due to delayed implantation, the gestation period can range from about 195 to 265 days. Pregnant Polar Bears den in the fall and give birth, generally to two cubs, in the winter. The cubs grow quickly on their mother’s fat-rich milk before emerging from the den in the spring.
Polar Bears are at the top of the Arctic food chain and primarily eat seals. Their populations are declining due to the disappearance of sea ice, and experts estimate that only 20,000-25,000 Polar Bears are left in the wild. Some scientists believe if the warming trend continues two-thirds of the population could disappear by the year 2050.
The Polar Bear is currently classified as “Vulnerable” on the IUCN Red List of Threatened Species. At least three of the nineteen subpopulations are currently in decline.
