At 6,120 meters deep, our ROV crossed a flat, silty seafloor under bright lights. A nearly transparent animal drifted into view about 1–2 meters from the camera, moved smoothly for a few seconds, then curved away and disappeared back into the dark. We didn’t see it hunt, glow, or touch the bottom, and we can’t ID the exact species from this clip. #discovery #deepsea #news #creepy #Science
