White whale calf

An extremely rare white humpback whale calf has been spotted near Australia's Great Barrier Reef, believed to be just a few weeks old, the baby humpback was seen at Cid Harbour in the famous reefs' Whitsunday Islands area.

White whales are highly unusual, with only 10-15 believed to exist among the 10,000-15,000 humpbacks living along Australia's east coast, and purely white ones - rarer still. Its parents could both have been dark humpbacks carrying the recessive white whale gene.

Migaloo is the world's best-known all-white humpback and has built up a loyal following in Australia since first being sighted in 1991. Humpback whales are currently on their southern migration, the baby's sex is currently unknown.
