A tiny blue octopus that lives in the deep sea off the coast of the Galápagos Islands is so small that it can fit in the palm of a hand. And as a team of researchers coordinated by Chicago's Field Museum announced in a new study just published in the journal Zootaxa, it now has an official name— Microeledone galapagensis. The octopus was first spotted in 2015 during a deep-sea expedition aboard the research vessel E/V Nautilus . From there, marine biologists used a remotely operated underwater vehicle (RoV) to explore the ocean floor near Darwin Island, at the northern end of the Galápagos archipelago. As the RoV's camera moved across the seafloor near an underwater slope at a depth of 1,773 meters (5,817 feet), they noticed the tiny octopus with its vibrant blue coloring. By performing a close inspection, the researchers were able to recover the blue octopus and film two other specimens, and then, at the end of the mission, conduct a thorough analysis.…
