New deep-sea sighting: The barreleye fish has a transparent head and tubular eyes

I spy with my barreleye, a new Fresh from the Deep! During a dive with our education and outreach partner, the Monterey Bay Aquarium, the team came across a rare treat: a barreleye fish (Macropinna microstoma).

MBARI’s remotely operated vehicles have logged more than 5,600 successful dives and recorded more than 27,600 hours of video—yet we’ve only encountered this fish nine times!
