Immediately I knew it was something really special
En las profundidades del océano Pacífico, a casi un kilómetro y medio bajo la superficie, la ciencia encontró lo que siempre ha buscado: una forma de vida completamente desconocida. Un pequeño pulpo azul del tamaño de una pelota de golf, bautizado como Microeledone galapagensis, fue identificado cerca de la Isla Darwin en el archipiélago de las Galápagos, recordándonos que los océanos guardan aún más misterios que respuestas. Su descubrimiento, que tardó más de una década en confirmarse, es también un testimonio de cómo la paciencia científica y la tecnología pueden preservar lo que antes habría sido necesario destruir para comprender.
- Un robot submarino avistó en 2015 una criatura azul diminuta a 1.768 metros de profundidad, pero nadie supo durante años exactamente qué era lo que había encontrado.
- El único ejemplar capturado planteó un dilema ético y científico: el método tradicional para describir una nueva especie de pulpo exige disección, lo que habría destruido el único testigo físico de su existencia.
- En lugar de cortar, los investigadores recurrieron a un escáner CT de alta definición, la misma tecnología médica que examina cuerpos humanos, para construir un modelo tridimensional completo sin dañar el espécimen.
- Tras más de una década de análisis, revisión y publicación en la revista Zootaxa, Microeledone galapagensis fue confirmado oficialmente como una especie nueva para la ciencia, intacta y documentada.
- El hallazgo subraya que incluso en uno de los ecosistemas marinos más estudiados y protegidos del mundo, el fondo del océano sigue siendo un territorio en gran parte inexplorado.
En las aguas profundas del archipiélago de las Galápagos, Patrimonio de la Humanidad de la UNESCO, un robot submarino capturó algo que nadie había catalogado jamás: un pulpo azul del tamaño de una pelota de golf, flotando cerca de la Isla Darwin a casi 1.800 metros de profundidad. Investigadores de la Fundación Charles Darwin y el Field Museum de Chicago anunciaron esta semana su nombre oficial: Microeledone galapagensis.
El ejemplar fue trasladado a la Estación Científica Charles Darwin, donde Janet Voight, curadora emérita de invertebrados del Field Museum y autora principal del estudio, reconoció de inmediato que se trataba de algo extraordinario. El problema era que solo existía uno, y describir formalmente una nueva especie de pulpo normalmente requiere disección.
En lugar de destruir el único ejemplar, el equipo lo envió a Chicago para someterlo a un escáner CT de alta definición. La máquina generó miles de imágenes de rayos X en corte transversal que los científicos ensamblaron en un modelo digital tridimensional, revelando la anatomía completa del animal —órganos, pico, tejidos— sin hacer un solo corte.
Curiosamente, el pulpo había sido avistado por primera vez en 2015, pero confirmar que se trataba de una especie genuinamente nueva requirió más de una década de análisis riguroso y revisión científica. Los resultados fueron publicados en la revista Zootaxa. El hallazgo es un recordatorio de que las profundidades del océano siguen siendo en gran medida desconocidas, y de que las herramientas que desarrollamos para explorarlas nos permiten cada vez más aprender sin destruir lo que encontramos.
In the deep waters off the Galápagos, nearly a mile and a half below the surface, a submersible robot found something no one had ever catalogued before: a tiny blue octopus, no larger than a golf ball, drifting near an underwater mountain close to Darwin Island. Researchers from the Charles Darwin Foundation and the Field Museum of Chicago announced the discovery this week, formally naming the creature Microeledone galapagensis. The find came from an expedition that sent a robotic submersible to probe the ocean floor in one of the world's most protected marine zones—the Galápagos archipelago, designated a UNESCO World Heritage site in 1978.
The octopus was collected along with other deep-sea specimens and transported to the Charles Darwin Research Station. When Janet Voight, the Field Museum's emeritus curator of invertebrates and lead author of the study describing the new species, saw the photograph, she knew immediately that the team had found something extraordinary. But there was a problem: they had only one specimen, and the standard method for documenting a new octopus species requires dissection—cutting open the animal to examine its beak, mouth, and internal organs in detail.
Voight and her colleagues faced a choice that would have been impossible just years earlier. Destroying their only example would mean losing the specimen forever. Instead, they sent it to Chicago and subjected it to a high-definition CT scanner, the same technology hospitals use to image human bodies. The machine took thousands of cross-sectional X-ray images, which researchers then compiled into a precise three-dimensional digital model of the octopus's interior and exterior anatomy. They could see everything—the structure of its organs, the shape of its beak, the arrangement of its tissues—without making a single cut.
This approach to scientific discovery represents a quiet shift in how researchers study rare and irreplaceable specimens. The CT scan revealed the octopus's anatomy in complete detail, allowing Voight and her team to confirm that Microeledone galapagensis was indeed a species previously unknown to science. The findings were published in the journal Zootaxa, the formal record of the discovery.
What makes the timeline curious is that the octopus was first spotted by the submersible robot back in 2015, but the research, scanning, and peer review necessary to confirm it as a new species took more than a decade. The delay reflects the meticulous work required to establish that an organism is genuinely new—not a known species in an unusual state, not a variant of something already named, but a distinct form of life. The Galápagos, despite centuries of scientific attention, continues to yield creatures that have never been formally described. This octopus, smaller than a golf ball and living in crushing darkness more than a kilometer down, is a reminder that the ocean's depths remain largely unknown, and that the tools we develop to study them—whether robots or scanners—keep expanding what we can learn without destroying what we find.

We only had one specimen, so I didn't want to take it apart— Janet Voight, on the decision to use CT scanning instead of dissection
The Hearth Conversation Another angle on the story
Why does it matter that they didn't dissect this one octopus? Couldn't they just study it the way scientists have always done?
Because they only had one. If you cut it open, it's gone. With CT scanning, the specimen survives, and future researchers can study it again with even better technology in ten years.
So this is really about preservation as much as discovery?
Exactly. It's a shift in thinking—especially for rare deep-sea creatures where you might never find another one. The scan gave them everything dissection would have, but the octopus still exists.
How did they even know it was new? Couldn't it just be a small version of something already known?
That's what took so long. They had to compare its anatomy—the beak shape, organ placement, everything—against every other octopus species on record. Only after that detailed work could they say with certainty: this is something we've never seen before.
And it's been sitting in the Galápagos the whole time, just waiting to be found?
For who knows how long. The ocean at that depth is barely explored. We find new species there regularly, but most of them we never see at all.
