Tiny ‘alien-like’ blue octopus discovered near Galápagos stuns scientists

But what first looked like an adorable deep-sea encounter soon turned into a scientific mystery.

Why scientists knew this octopus was something unusual

After collecting specimens and bringing them back to the Charles Darwin Foundation’s research station, scientists realised they could not identify the creature as any known octopus species. To understand what made it different, the team used micro-CT scanning, an advanced imaging technique that creates detailed 3D images of internal structures using X-rays.

That closer look revealed several unusual features. Unlike many known octopuses, this one had:

• relatively few suckers on its arms
• smooth skin
• distinct beak characteristics
• unusual colouration around parts of its organs and mantle

These details helped researchers confirm they were looking at a species never documented before.

Scientists also discovered that one specimen had 13 eggs in its ovaries, giving early clues about how the species reproduces.

The findings were recently published in the journal Zootaxa. The discovery is also a reminder of how little humans still know about the deep sea. While the Galápagos Islands are famous for extraordinary wildlife like giant tortoises, marine iguanas and Darwin’s finches, the dark waters far below remain largely unexplored.

And if a tiny electric-blue octopus can stay hidden there for this long, scientists suspect many more strange, and perhaps equally adorable, creatures may still be waiting to be found.
