Still frame of a rattail from a Medusa deployment during the Bioluminescence and Vision on the Deep Seafloor 2015 expedition. The Medusa lander uses red light illumination that is invisible to most deep-sea inhabitants and an intensified camera that amplifies both this dim illumination as well as any bioluminescence. This allows scientists to unobtrusively observe animal behavior and bioluminescence on the deep seafloor.
