Rarely seen deep-sea barreleye fish filmed in 4K
During a recent expedition aboard the research vessel David Packard, MBARI scientists encountered a rarely seen barreleye fish (Macropinna microstoma). This sighting is MBARI's 11th observation of this unique deep-sea fish with a transparent head.
During a deep-sea research expedition, scientists from the Monterey Bay Aquarium Research Institute (MBARI) captured stunning 4K footage of a rarely seen barreleye fish (Macropinna microstoma). This unique deep-sea creature, known for its transparent head, was observed approximately 600 meters underwater. The sighting marked the 11th documented observation of the species for MBARI researchers.
The fish was first spotted by research specialist Shannon Johnson while the ROV Doc Ricketts was being recovered. The team quickly regrouped in the control room as the ROV pilot, Cameron Law, maneuvered the vehicle to get a closer look at the fish using a high-resolution 4K camera. The barreleye's tubular eyes rotate beneath a dome of transparent tissue, allowing it to track prey while protecting its eyes from stinging siphonophore tentacles.
This transparent head shield also provides stability and maneuverability as the fish drifts in place. The footage will serve as a valuable resource for further research on this elusive species.
