The first polar bear cub born in Australia in nearly 30 years has started to growl and open its eyes.

The unnamed cub was born on May 9 at Sea World in Queensland. Animal caretakers said they had been hearing strange noises coming from a pitch black "maternity den" for several weeks before realizing it was the cub starting to growl, according to a post on the Sea World website.

Zookeepers won't know the sex of the baby until it emerges from the den later this month, the Australian Associated Press reports.

Polar bears have long been a symbol of the climate change fight, and face shrinking habitats, food scarcity and the threat of turning brown as temperatures rise.
