Rare White Humpback Calf Spotted Off Australia Coast

Imagine looking out at the ocean and seeing what looks like a small iceberg floating alongside a whale. That's exactly what happened when a rare white humpback calf appeared off the coast of New South Wales and Queensland last week.

The mostly white baby whale was first captured on drone footage swimming beside its mother at Cabarita Beach on Friday. The next day, excited crowds spotted the same pair about 60 miles north at Minjerribah on Stradbroke Island.

Dr. Eva Plaganyi, a scientist with CSIRO, was among those watching from shore when the calf appeared just 20 meters offshore. "We saw that this calf was almost all white, so looking almost like a small iceberg floating by against the dark of the female whale," she said. "Really exciting sighting and not something I've seen in my four decades of whale watching."

Scientists believe the calf is leucistic, meaning it has some pigment and normal dark eyes, unlike completely white albino whales. This rare genetic trait appears in only about a dozen humpback whales across the Southern Hemisphere.

The calf might be related to Migaloo, Australia's beloved all-white humpback who became famous after his first sighting in Byron Bay in 1991. Genetic testing would be needed to confirm whether Migaloo is the father, but either way, this newborn has already captured hearts up and down the coast.

The Ripple Effect

The rare sighting is energizing citizen scientists along Australia's eastern coastline. Because the white calf is so visible against the dark ocean, everyday whale watchers can help track its journey north to the warmer waters of Hervey Bay.

"The non-scientists helping out is really wonderful because they can spot things that we don't see, and through social media, we can document whale movements," said Dr. Vanessa Pirotta, a whale scientist at Macquarie University. The calf could show up anywhere during its lifetime, from New Zealand to Brazil.

The newborn will stay with its mother for about a year as they continue their annual migration. Australia has strict protections for whales, and because this one is mostly white, those rules are even tighter. Boats must stay 500 meters away, and aircraft need to maintain 610 meters of distance.

Being white might make the calf more visible to predators, but it also means people will be able to spot and protect this special whale throughout its entire life. As peak whale-watching season continues through October, thousands more people will have the chance to witness this once-in-a-lifetime sight swimming along Australia's coast.
