Then, about 20 hours into the recording from the Medusa’s fifth deployment, Dr. Robinson saw the sharp points of tentacles sneaking into the camera’s view. “My heart felt like exploding,” he said on Thursday, over a shaky phone connection from the ship’s bridge.

At first, the animal stayed on the edge of the screen, suggesting that a squid was stalking the LED bait, pacing alongside it.

And then, through the drifting marine snow, the entire creature emerged from the center of the dark screen: a long, undulating animal that suddenly opened into a mass of twisting arms and tentacles. Two reached out and made a grab for the lure.

For a long moment, the squid seemed to explore the strange non-jellyfish in puzzlement. And then it was gone, shooting back into the dark.
