A migrating humpback near Byron Bay is completely white from albinism - how did one missing DNA letter let him survive?
A whale with one missing DNA letter turned completely white
In this episode, we present the sighting, science and social debate that followed the white humpback’s appearance and decades of returning migrations. We outline the genetic finding, the protections and the public attention, and ask what his story reveals about visibility, risk and law.
Person: Migaloo
Location: Byron Bay, east coast of Australia
Date: 28 June 1991
Topic: Oculocutaneous albinism type 1A confirmed by genetic analysis
- Observers on shore first stopped to watch when a completely white humpback surfaced during the 1991 migration.
- Genetic analysis in 2012 found a single cytosine deletion in the tyrosinase gene, truncating the protein and halting melanin production.
- Physical signs matched molecular diagnosis: pink-tinged blowhole, pink eyes, lack of countershading, and pale healing scars.
- Recorded migratory behavior showed sustained annual migrations for nearly three decades and higher-than-average travel speed.
- Legal protections were enacted: 500 m vessel exclusion, 610 m aircraft exclusion, and rules extended to any humpback over 90% white coloration.
