Tiny Blue Octopus ‘the Size of a Golf Ball’ Discovered Near the Galápagos Islands

A remarkable new octopus species has been unveiled by scientists, discovered nearly 6,000 feet deep in the waters surrounding the Galápagos Islands. This discovery, which has been named Microeledone galapagensis, was documented in the scientific journal Zootaxa. The small, bright-blue organism was first identified during an exploratory mission in 2015 aboard the research vessel E/V Nautilus, in collaboration with the Charles Darwin Foundation and the Galápagos National Park Directorate.

The expedition focused on the marine habitats near Ecuador’s renowned archipelago, a location famously linked to Charles Darwin, whose groundbreaking work supports the theory of evolution. The octopus, which is about the size of a golf ball, was located near Darwin Island and captured the interest of researchers taking part in the mission. Observations recorded during the dive included excited remarks from the scientists, as one exclaimed, “He’s tiny!” while another noted, “It’s blue!”

The octopus was first glimpsed by pilots operating a remotely controlled submersible, nearing 5,800 feet beneath the ocean’s surface. Initial footage of the creature prompted researchers to collect the specimen, and further video documentation revealed at least two additional octopuses that appeared to share similar characteristics.

Upon returning to the Charles Darwin Research Station, scientists began to differentiate the newfound specimen from numerous other deep-sea organisms collected throughout the expedition. This prompted them to reach out to Janet Voight, an octopus expert affiliated with the Field Museum in Chicago. Voight instantly recognised the significance of the find, stating, “I’d never seen anything like it.”

Determining the classification of Microeledone galapagensis posed a considerable challenge for the research team. Traditionally, identifying new species often requires dissection to examine features such as beaks and internal anatomy. However, with only a single specimen available, the researchers were hesitant to damage the unique find. Instead, they opted for advanced micro-CT scanning technology to create intricate 3D imaging without harming the octopus.

Stephanie Smith, a co-author of the research article, emphasised the importance of this non-destructive method, particularly for key specimens like this one. “There’s nothing like spending the day looking at something no other human has ever seen,” Smith remarked. The scans provided sufficient anatomical information to confirm that this organism was indeed a distinct new species.

For Voight, this discovery represents a personal milestone in her extensive career studying octopus evolution, marking the first newly identified octopus species she has described in over forty years. She fondly remarked, “These are little octopuses that live in the deep sea, and hardly anybody on Earth has ever gotten to see them. I just feel lucky that I got to work with them.”

This remarkable find underscores the fact that a significant portion of the deep ocean around the Galápagos Islands remains unexplored. The region’s complex underwater ecosystems continue to captivate scientists and highlight the pressing need for further research into its rich biodiversity. As the depths of the ocean still harbour many secrets waiting to be uncovered, discoveries like Microeledone galapagensis pave the way for new insights into marine life and evolution.

Researchers remain hopeful that future expeditions will shed light on the many other undiscovered species that inhabit the vast and largely uncharted waters of the deep ocean. The unique environments found in such locations offer significant opportunities for breakthroughs in our understanding of marine ecosystems and their inhabitants.
