Sea World Australia released video footage on Tuesday, May 2, of two newborn polar bear cubs feeding from their mother inside their den.
These cubs, which are not named yet, were born last week on April 26. They live at Sea World Australia with their 16-year-old mother Liya.
At birth, they were 1 pound 5 ounces (600 grams) and 6 inches (15 centimeters). They will grow up to be as tall as 11 feet (3.35 meters) and weigh up to 1,400 pounds (635 kg).
The cubs will spend their time in the maternity den until July.
