Rare albino humpback whale spotted near Australia

AUSTRALIA (KGO) -- A rare albino humpback whale nicknamed "Migaloo" has been spotted again off Australia's eastern coast.

Migaloo is one of only a small handful of documented all-white humpback adults. He was first seen in 1991 when he was a juvenile. Researchers believe he's now in his 20's.

Migaloo doesn't show up every year, but this is the third year in a row he's been spotted. He's currently on annual migration from the Antarctic to the humpback's breeding grounds along the Great Barrier Reef.
