When he was first spotted back in 1991, Migaloo was the first all-white humpback researchers had ever seen. According to The White Whale Research Center, Migaloo was believed to be the only all-white humpback until last September, when a white calf was spotted near the Great Barrier Reef.
Every year since, whale watchers have kept an eye out for the albino beastie, hoping to catch a glimpse of him during his annual migration from Australia to the Antarctic. Male humpbacks can travel up to 87 miles (140 kilometers)a day during their migration, according to experts. Whale watchers may be able to enjoy Migaloo for decades. Humpback whales are believed to survive as long as 90 years in the wild.
