Polar Cubs at Hellabrunn Zoo Pawing Around and Opening Their Eyes

Tiny polar bear twin cubs born in Munich, Germany are making good progress in early stages of development. The cubs were born at the Hellabrunn Zoo on December 9th.

Male polar bears can be two to three times larger than female polar bears. Males range from about 8-10 feet in length, while females are generally 6-8 feet in length. Their tails are 3-5 inches long. Male polar bears can weigh up to three times as much as the females. Males are typically 550-1700 lbs, and females are 330-650 lbs. Polar bears reach maturity between the ages of 3 and 5 years.

The pregnant female polar bear gains about 440 lbs to sustain both herself and her cubs throughout her pregnancy — the gestation period is eight months.

Hairless, blind and deaf, cubs weigh about 1 pound at birth, but are nursed to a weight of 20-30 pounds by the time they leave the den in March or April.

Hellabrunn Zoo is a 89-acre zoological garden in Munich. The zoo was the first zoo in the world not organized by species, but also by geographical aspects — a Geo-Zoo. In 2010 it was home to 17,811 animals representing 709 species.

In 1922, the zoo was closed due to the inflation in Germany. It was re-opened on May 23, 1928.

The zoo was heavy damaged by allied air raids, but re-opened in May 1945.
