A new species of octopus, approximately the size of a golf ball, has been identified in the deep waters surrounding the Galápagos Islands. The discovery, announced in the journal Zootaxa, was made using a remotely operated vehicle during a 2015 expedition and confirmed through advanced CT scanning. This marks the first official species description led by lead author Janet Voight in her 40-year career.
Facts First
- A new species of tiny blue octopus has been identified in the deep waters near the Galápagos Islands.
- The octopus, named Microeledone galapagensis, is about the size of a golf ball and was observed at a depth of approximately 5,800 feet.
- The discovery was confirmed using micro CT scans that revealed internal anatomy without dissection.
- The finding was made during a 2015 expedition conducted by the E/V Nautilus in partnership with the Charles Darwin Foundation (CDF) and Galápagos National Park Directorate.
- This is the first new octopus species description officially led by lead author Janet Voight in her 40-year career.
What Happened
A new species of octopus, named Microeledone galapagensis, has been identified in the deep waters surrounding the Galápagos Islands. The discovery was announced in the journal Zootaxa. The octopus was first spotted during a 2015 deep-sea expedition using the exploration vessel E/V Nautilus, conducted in partnership with the Charles Darwin Foundation (CDF) and the Galápagos National Park Directorate. Researchers used a remotely operated underwater vehicle (ROV) to investigate the seafloor near Darwin Island, observing the octopus on an underwater mountain approximately 5,800 feet (1,773 meters) below the surface. The team collected one specimen and recorded video footage of two other individuals.
Why this Matters to You
This discovery expands the known biodiversity of one of the world's most iconic and protected ecosystems, the Galápagos Islands. For you, it underscores that even in well-studied areas, significant scientific discoveries are still being made, which may lead to a better understanding of deep-sea ecosystems and their conservation needs. The use of non-invasive CT scanning technology in this process represents a modern, precise method for scientific classification that could be applied to other fields of research.
What's Next
The specimen and data are now part of the scientific record, and the formal description of Microeledone galapagensis provides a baseline for future research. Scientists may now look for this species in other deep-sea regions to understand its range and ecology. The successful partnership between the expedition team, the Charles Darwin Research Station, and the Field Museum demonstrates a model for collaborative international research that could be replicated for other deep-sea explorations.
