Marine fish known only from International Waters that occur within 200 meters of the surface include a scorpionfish Scorpaenodes immaculatus (p. 7 of IngentaConnect pdf file) and a moray eel Gymnothorax parini(FishBase) from Walters Shoals, the Meteor Dragonet Protogrammus sousai(Marine Species) from the Great Meteor seamount, and a rover Plagiogeneion geminatum(FishBase)

Areas in international waters likely to be important for endemic species include seamounts (Oceanography Soc. pdf file), deep sea trenches (Shining a Spotlight), hydrothermal vents (ChEss), and cold seeps (ChEss).
