This chimaera swam slowly past the remotely operated vehicle, giving us a good view of the lateral lines running across its head that allow it to detect pressure waves (like our ears). The dotted-looking lines near the fish’s mouth are called “ampullae of Lorenzini” and they can detect perturbations in electrical fields generated by living organisms. This encounter took place at a depth of 1,735 meters (5,962 feet) during Dive 06 of the second Voyage to the Ridge 2022 expedition.
