A viperfish (<em>Chauliodus sp</em>) (center) shortly after collection in a tucker trawl dragged at 500 meters depth over the Davidson Seamount. This midwater fish looks fierce with its elongated teeth, but is a mere few centimeters long. Midwater fishes are constantly playing a game of cat and mouse with predator and prey, as they migrate up to the surface at night and back to depth during the day.
