A group of whale watchers got a special treat when they spotted a rare white humpback whale off Australia's Gold Coast on Monday.

The whale was filmed by a group of whale enthusiast as it swam close to the surface in the waters off of Queensland, Australia.

Queenland's 7 News also filmed the whale for an extended period of time slightly beyond the Gold Coast Seaway, where Moreton Bay meets the Pacific Ocean.

"It was just traveling along, cool as a cucumber, white as snow," one tourist told 7 News during an interview.

Speculation arose that the albino whale was the iconic Migaloo, a famous white humpback that was first discovered back in 1991. Migaloo has since been seen on several other occasions up until 2008.

For a time, Migaloo was the only white humpback known in the world. However, three others were later identified, although they aren't completely white like Migaloo.

Researchers say that it is unlikely that the whale spotted on Monday was actually Migaloo, which is bigger in size and not quite as white.

Other whale experts in Queensland believe that the whale spotted is the "Migaloo Junior," Migaloo's calf, says White Whale Research Centre founder Oskar Peterson. This whale was first seen in 2011 as a calf swimming near the Great Barrier Reef. However, it has not been confirmed whether or not it is really Migaloo's calf.

Scientists have identified one other known white humpback, which is differentiated by the spots on its tail.

Whether or not the whale was Migaloo or his junior, it was still an unique and unexpected sight to see.

According to CBC News, about 23,000 whales of all species pass by the Gold Coast as they travel from Antarctica to warmer waters to the north.
