Rare albino whale spotted off Australia coast

AUSTRALIA (KABC) -- A rare albino humpback whale was spotted off the eastern coast of Australia for a third year in a row.

Researchers have nicknamed the all-white whale "Migaloo." He's one of only a small handful of documented all-white humpback adults.

Migaloo was first seen in 1991 when he was a juvenile. Researchers believe he's now in his 20s.

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.
