Several feet from the SuBastian’s chunky robotic arm, the octopus flexed her own spaghetti-thin appendages for the first time, propelling herself out from under her mother. Two miles up, watching the video feed from the control room of the research cruiser Falkor (too), marine biologist Diva Amon saw it happen. 

As more hatchlings scooted across the screen, the dozens of scientists and crew members on board—all members of the Schmidt Ocean Institute’s “Octopus Odyssey” expedition—became exuberant. “There was squealing and excitement and pointing,” recalls Beth Orcutt, a geomicrobiologistat the Bigelow Laboratory for Ocean Sciences and one of the expedition’s chief scientists. “It was a riot,” says Jorge Cortés-Núñez, the other chief scientist and a coral reef specialist at the University of Costa Rica. “It was spectacular.
