Chimaera
This cute chimaera stopped to say hello to remotely operated vehicle Deep Discoverer during a dive off the coast of Florida, 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 ampullae of Lorenzini that can detect perturbations in electrical fields generated by living organisms. Hey little, buddy!
