Never had seen something like it, and it changed everything
En las profundidades del Pacífico, a más de un kilómetro y medio bajo la superficie, una criatura del tamaño de una pelota de golf habitaba en la oscuridad sin que la ciencia supiera de su existencia. Durante una expedición en 2015 cerca de la isla Darwin, en el archipiélago de las Galápagos, un robot submarino recogió un pequeño pulpo azul que resultaría ser una especie completamente nueva: Microeledone galapagensis. Su hallazgo nos recuerda que el océano profundo sigue siendo uno de los últimos grandes misterios del planeta, y que protegerlo es también proteger lo que aún no conocemos.
- Un único ejemplar, frágil y sin clasificar, llegó a un laboratorio de Chicago como el único representante conocido de una especie que la ciencia nunca había visto.
- La especialista en cefalópodos Janet Voight se enfrentó a un dilema: diseccionar el animal para estudiarlo significaba destruir el único ejemplar existente.
- Para preservarlo intacto, los investigadores recurrieron a la tomografía computarizada, obteniendo un modelo tridimensional detallado de sus órganos internos sin realizar un solo corte.
- El análisis confirmó que se trataba de una especie nueva, bautizada Microeledone galapagensis, hallada a 1.768 metros de profundidad cerca de una montaña submarina.
- El descubrimiento subraya cuánto queda por explorar en las aguas profundas de las Galápagos y refuerza la urgencia de conservar este Patrimonio Mundial de la UNESCO.
Un pequeño pulpo azul, no más grande que una pelota de golf, fue recogido por un robot submarino durante una expedición en 2015 cerca de la isla Darwin, en las Galápagos, a una profundidad de 1.768 metros. Nadie a bordo del E/V Nautilus, que colaboraba con la Fundación Charles Darwin, supo identificarlo. El ejemplar fue preservado y enviado a Chicago, donde Janet Voight, especialista en pulpos del Field Museum, confirmó que nunca había visto nada parecido.
El reto era mayúsculo: describir una nueva especie exige examinar cada detalle anatómico, pero Voight solo contaba con un único animal. Diseccionarlo habría significado perderlo para siempre. Junto a Stephanie Smith, responsable del laboratorio de tomografía del museo, optaron por escanearlo con rayos X, obteniendo un modelo digital tridimensional que reveló su estructura interna sin dañarlo. Así nació oficialmente Microeledone galapagensis.
Más allá de la taxonomía, el hallazgo ilumina la vastedad de lo desconocido. El océano profundo de las Galápagos es un ecosistema casi inexplorado, tan remoto como la superficie de otro planeta. Cada especie descubierta en sus aguas es un argumento más para preservar este archipiélago, Patrimonio Mundial de la UNESCO desde 1978, y una advertencia de que esa protección no puede darse por garantizada.
A small blue octopus, no larger than a golf ball, was pulled from the darkness of the Pacific more than a mile below the surface. The creature had drifted through the waters near Darwin Island in the Galápagos archipelago, unknown to science, until a remote-operated robot collected it during a deep-sea expedition in 2015. That single specimen—fragile, preserved, and shipped to a laboratory in Chicago—would become the foundation for naming an entirely new species.
The discovery emerged from a collaboration between researchers aboard the E/V Nautilus and the Charles Darwin Foundation, which manages scientific work across the Galápagos. The expedition focused on exploring the ocean floor near the northern reaches of the island chain, roughly a thousand kilometers from Ecuador's mainland coast. At a depth of 1,768 meters, the robot's camera caught sight of the octopus moving across the seafloor near an underwater mountain. The crew maneuvered the submersible to collect it, along with other deep-sea specimens gathered during the mission, and transported everything back to the Charles Darwin Research Station.
When researchers began cataloging their haul, the small blue octopus stood out immediately. No one could identify it. The team reached out to Janet Voight, an octopus specialist at Chicago's Field Museum and one of the world's leading authorities on cephalopods. They sent her a photograph. Voight's response was unambiguous: she had never seen anything like it. The specimen was preserved in alcohol and formalin, then shipped to Chicago for closer examination.
Here the work became delicate. Describing a new octopus species requires examining every anatomical detail—the mouth, the beak, the teeth. Normally, this means opening the specimen, dissecting it, laying bare its internal architecture. But Voight had only one animal to work with. Destroying it in the name of study felt like a loss she could not justify. Instead, she partnered with Stephanie Smith, who manages the Field Museum's CT scanning laboratory, to image the octopus without cutting it open.
CT scanning compiles thousands of X-ray slices into a three-dimensional digital model, revealing the interior of an object in perfect detail while leaving it physically intact. The technique allowed the researchers to see the octopus's internal organs, its mouth structure, and the fine anatomical features that would establish it as a species previously unknown to science. They named it Microeledone galapagensis—a creature of the deep Galápagos, small enough to fit in your palm.
The discovery carries weight beyond taxonomy. These octopuses inhabit a realm almost no human has ever witnessed. The deep ocean around the Galápagos remains largely unexplored, a frontier as remote as the surface of another planet. Each new species found in these waters is a reminder of how much remains hidden, how little we truly understand about the ecosystems that sustain life on Earth. Salome Buglass, a marine scientist who worked with the Charles Darwin Foundation and contributed to the study, framed it plainly: every discovery like this one teaches us something essential about these hidden worlds and why protecting them matters. The Galápagos has been a UNESCO World Heritage site since 1978, recognized as irreplaceable. The blue octopus, pulled from the abyss and named, becomes another reason why that protection cannot be taken for granted.

I immediately knew it was something really special. I had never seen anything like it.— Janet Voight, octopus specialist at the Field Museum of Chicago
Discoveries like these remind us how much of the deep ocean in Galápagos remains unexplored. Each new species helps us understand these hidden ecosystems and why it is important to protect them.— Salome Buglass, marine scientist and Charles Darwin Foundation researcher
La Conversación del Hearth Otra perspectiva de la historia
Why does finding a single octopus in the deep ocean warrant this kind of attention?
Because it's a species that has never been described before. We don't know how many of these creatures exist, what they eat, how they reproduce. One specimen is enough to change our understanding of what lives down there.
But couldn't they have just dissected it and gotten the answers faster?
They could have, but then there would be nothing left. With only one animal, you have to choose between destroying it for knowledge or preserving it and finding another way. They chose the latter.
And the CT scanning actually worked?
It worked perfectly. They could see inside the octopus—its organs, its beak, everything they needed—without ever opening it. It's a technique that's changing how museums and researchers approach rare specimens.
What does this tell us about the Galápagos?
That we've barely scratched the surface. The deep waters around those islands are almost completely unexplored. This one octopus is a signal that there are probably hundreds of species down there we've never encountered.
Is that a conservation problem?
It's a conservation imperative. How do you protect something you don't even know exists? Every discovery like this one makes the case for marine protection stronger.
