Rare white humpback whale spotted

NEAR BRISBANE, Australia (CNN/SEVEN NETWORK) - A helicopter camera spotted a white humpback whale in the waters near Brisbane, Australia.

It's believed to be Migaloo, an elusive, yet quite famous, albino whale.

People on a whale-watching tour said seeing the creature was amazing. One person said it looked like an iceberg coming out of the waves.

If this is Migaloo, Wedneday's sighting would be the third of the year. He was first spotted 21 years ago and until last year was the only documented all-white whale in the world.
