Rare Sighting of Albino Pygmy Killer Whale off Oʻahu’s West Coast
Every so often, the ocean offers a glimpse of something so rare, so otherworldly, it lingers in memory long after the waves settle. This spring, while cruising the deep blue off Waiʻanae, our Wild Side crew encountered just such a marvel: an albino pygmy killer whale.
Pygmy killer whales (Feresa attenuata) are elusive enough—deep-diving, shy, and often misidentified due to their rarity. But among the small population known to frequent the offshore waters of Oʻahu’s west coast, one individual stands out in the most literal sense. With pale white skin and a pink-tinged rostrum, this albino whale cuts a striking figure among the typically charcoal-colored pod mates.
On a clear morning in April, our team spotted a pod of approximately 18 pygmy killer whales traveling slowly in loose formation. We recognized a few familiar fins from past encounters—including adult males with distinctive notches and a calf riding in close echelon position with its mother. But it was the pale flash at the surface that caused all eyes to lock forward.
The albino individual surfaced several times near the bow, staying close to the center of the group. Despite its pigmentation difference, its behavior was unremarkable—which in this case is remarkable. It moved in synchrony with the pod, breathed calmly, and even briefly spyhopped, revealing more of its ghostly profile beneath glassy seas.
Albinism in cetaceans is extremely rare. It results from a genetic mutation that limits melanin production, often causing sensitivity to sunlight and sometimes impaired eyesight. But this individual appears well integrated and healthy, a hopeful sign that it’s thriving within its social group.
We’ve been privileged to encounter this albino whale on several occasions over the past few years, but each sighting is as jaw-dropping as the first. It’s a testament to the wonders still swimming just offshore—and the importance of preserving the marine environment these unique animals call home. Our team submitted photos and field notes from the encounter to Cascadia Research Collective, contributing to the ongoing cataloging of this little-studied species in Hawaiian waters. It’s moments like these that remind us why we do what we do: to witness, to document, and to inspire awe in the wild heart of Hawaiʻi.
