Tiny Blue Octopus Found 6,000 Feet Below Galápagos

A stunning blue octopus the size of a golf ball has been identified as a brand-new species after being discovered nearly 6,000 feet beneath the waters surrounding the Galápagos Islands.

The tiny creature first appeared in 2015 when researchers sent a remotely operated underwater vehicle to explore the seafloor near Darwin Island. As the robot explored an underwater mountain deep below the surface, scientists spotted something unusual crawling across the ocean floor.

"He's tiny!" one researcher exclaimed in audio recordings from the expedition. "It's blue!"

The team collected the specimen and brought it back to the Charles Darwin Research Station, where it immediately stood out among dozens of other deep-sea animals. Researchers contacted Janet Voight, an octopus expert at Chicago's Field Museum, and sent her photographs of the mysterious creature.

"Right away, I knew it was something really special," says Voight, who led the study recently published in the journal Zootaxa. "I'd never seen anything like it."

The team faced a unique challenge. Normally, identifying a new octopus species requires dissecting the specimen to examine its mouth, beak, and teeth. But they only had one confirmed specimen, and Voight didn't want to destroy such a rare find.

Instead, the researchers used advanced CT scanning technology at the Field Museum to create detailed 3D images of the octopus without cutting it open. The scans revealed clear views of internal organs and mouth structures that allowed scientists to officially classify it as a new species now named Microeledone galapagensis.

"There's nothing like spending the day looking at something no other human has ever seen," says Stephanie Smith, who managed the imaging work.

Why This Inspires

This discovery marks a personal milestone for Voight, who has studied octopus evolution for more than 40 years. Despite her long career, this is the first time she has officially led the description of a new species.

"These are little octopuses that live in the deep sea, and hardly anybody on Earth has ever gotten to see them," Voight says. "I just feel lucky that I got to work with them."

The find also reminds us how much ocean mystery remains to be explored. "If you took all the land on Earth and pieced it together, you would not cover the Pacific Ocean," Voight points out. "The oceans are so big, and there's so much left to explore."

Discoveries like this help scientists protect fragile ocean ecosystems that remain poorly understood, showing that even in Earth's most remote depths, there are still wonders waiting to be found.
