Migaloo, a rare white humpback whale migrating north along Australia’s east coast, is being monitored for skin cancer by experts as red marks were found on the whale.
The approximately 28-year-old whale, was first identified in 1991 and has since been seen regularly as he migrated off eastern Australia.
But photos and video showing a pink discoloration around Migaloo’s dorsal fin this season have some concerned that his long periods on the surface in the sun could be taking a toll on his unpigmented skin.
“It may well be just a growth, or it could be skin cancer, we’re just not too sure at the moment,” said White Whale Research Center founder Oskar Peterson.
Whale watchers say Migaloo’s appearance is still spectacular.
“He sort of glows in the water like a fluorescent blue,” Peterson told Australia’s ABC News. “He’s quite an amazing sight.”
