Scientists Spot Rare Ginkgo-Toothed Beaked Whale Alive for First Time, Take Biopsy
Shadows in an ocean we barely understand
Mark
So they shot a whale with a crossbow. That sounds alarming until you understand what actually happened.
Mimi
Right—it was a biopsy tool, not a weapon. The arrow has a punch tip designed to collect a tiny tissue sample. Henderson said it's comparable to an ear piercing in terms of discomfort.
Luke
But we should be clear: this was a living animal, and they did fire a projectile at it. The comparison to an ear piercing is Henderson's framing, not an independent measure of pain or stress to the whale.
Mimi
Fair point. What matters is that the procedure worked and gave them the genetic proof they needed after five years of searching.
Mark
Five years is a long time to chase a sound. What made them so certain they'd find something?
Mimi
They recorded an echolocation pulse in 2020 that didn't match any known species. That was enough. For scientists studying animals that are mostly known from dead specimens, a mystery signal is irresistible.
Luke
And beaked whales are genuinely understudied—Pitman's quote about them being "the largest, least-known animals left on the planet" is striking. But it's also worth noting that most of our knowledge comes from stranded animals, which skews what we actually know.
Mark
So this live sighting changes the picture.
Mimi
Completely. They found the species far outside its previously documented range. That alone reshapes what researchers thought they understood about where these whales live and how they move through the ocean.
Luke
Though we should note: one sighting, one small group. It's a breakthrough, but it's not a complete picture of the species' distribution or behavior.
Mark
What happens next?
Mimi
They keep listening. Three other beaked whale species have never been seen alive. The team is going back to the Pacific to follow more unidentified calls, hoping to find the next one.
O Pulso
- For five years, researchers chased a sonar signal through the North Pacific that matched no known species — a mystery stubborn enough to pull them back to the same open ocean, season after season.
- Beaked whales are among the least understood large animals on the planet, and the ginkgo-toothed species existed in science only as a handful of dead specimens — until a small group surfaced near Baja California last June.
- When one whale drifted within 20 meters of the boat, a scientist raised a 150-pound crossbow and fired a biopsy arrow, collecting the tissue sample that would finally crack the five-year mystery.
- The genetic results delivered a shock: the team had expected to find Perrin's beaked whales, but the DNA confirmed a species documented far outside its previously known range.
- The discovery now points toward three other beaked whale species that have never been seen alive, keeping the search alive across the Pacific for the next unidentified call in the dark.
In the vast and largely uncharted depths of the North Pacific, a five-year pursuit of an unidentified sound culminated last June in something science had never witnessed before — a living ginkgo-toothed beaked whale, surfacing near Baja California to confirm that the ocean still holds creatures beyond our knowing. The discovery reminds us that even the largest animals on Earth can remain almost entirely hidden, existing for decades as little more than names attached to the dead. A crossbow, a moment of proximity, and a strand of genetic material were enough to rewrite the boundaries of a species' known world — and to suggest that other shadows in the deep may yet be waiting to be named.
Five years of following an unidentified echolocation pulse through the North Pacific finally resolved last June, when researchers near Baja California encountered something no scientist had ever seen alive: a ginkgo-toothed beaked whale. The signal had first appeared in 2020, distinct enough from any known species to send the team back to the same waters year after year in search of its source.
Beaked whales are the largest animals on Earth that remain almost entirely unknown to science — understood mostly through dead specimens washed ashore. The ginkgo-toothed beaked whale was no different, existing in the scientific record only as a name attached to a few carcasses. When the animals finally appeared, they came as a small group: a female, a calf, and a scarred male bearing the species' signature leaf-shaped tusks, worn from years of underwater combat.
Sighting alone wasn't enough. Many beaked whale species are nearly indistinguishable by eye, and the team needed genetic proof. When one whale drifted close to the stern, researcher Robert Pitman used a crossbow fitted with a biopsy arrow to collect a small tissue sample — a procedure the lead author compared to getting an ear pierced, and one far less invasive than the bites cookiecutter sharks routinely take from deep-diving animals.
The results were a surprise. The team had expected to confirm Perrin's beaked whales, a species known from only six strandings off Southern California. Instead, the DNA identified ginkgo-toothed beaked whales — far outside their previously documented range. The discovery now raises the possibility of finding three other beaked whale species that have never been observed alive, as researchers continue listening to the Pacific for the next unidentified sound waiting to break the surface.
Five years of chasing a sound through the North Pacific finally paid off last June when researchers working near Baja California spotted something no scientist had ever seen alive: a ginkgo-toothed beaked whale. The discovery began in 2020, when a team recorded an unfamiliar echolocation pulse echoing through the water—a signal that didn't match any known species. That mystery was enough to send them back to the same region year after year, searching the open ocean for whatever was making that call.
Beaked whales are the largest animals on Earth that remain almost entirely unknown to science. Most of what researchers understand about them comes from dead specimens washed ashore or found floating. Robert Pitman, a scientist at Oregon State University who has spent decades studying these creatures, described them as shadows in an ocean we barely understand. The ginkgo-toothed beaked whale was no exception—it existed in the scientific literature as a name attached to a handful of dead animals, nothing more.
When the whales finally surfaced, they came in a small group: an adult female, a calf, and a heavily scarred male with small, leaf-shaped tusks worn from underwater combat. Male ginkgo-toothed beaked whales grow these distinctive teeth low in their jaw, using them strictly for fighting and mating access. Females of the species never develop teeth at all. Instead, both sexes feed by suction, drawing prey into their mouths from the deep.
But seeing them wasn't proof enough. Several beaked whale species look nearly identical, and after years of pursuing false leads, the team needed genetic confirmation. When one whale drifted within about 20 meters of their boat's stern, Pitman picked up a 150-pound crossbow fitted with a punch-tip arrow and took a small tissue sample. The procedure lasted a moment—Elizabeth Henderson, the study's lead author, compared the sensation to getting an ear pierced. Pitman noted that cookiecutter sharks, which bite chunks out of almost every deep-diving animal, remove far more tissue in a single bite.
The genetic results delivered a surprise. The researchers had expected to find Perrin's beaked whales, a species known only from six animals that had stranded off Southern California. Instead, the test confirmed ginkgo-toothed beaked whales—a species documented far outside its previously known range. Henderson told Live Science the team was shocked but thrilled. After five years of searching, they finally had an answer to the mystery that had drawn them back to the same waters again and again.
The discovery opens a door to other possibilities. Three additional beaked whale species have never been spotted alive by humans. The team plans to continue tracking unidentified calls across the Pacific, hoping that those remaining ghosts might surface one day too. Each unusual sound in the water could be the next species waiting to be found, the next shadow ready to break the surface.
