List of deep-sea actinopterygian families with mean maximum depth >1000 m and with >10 species. Numbering (N) is in the order of listing in FishBase (Froese & Pauly, 2013). Habitat is the predominant type recorded in FishBase. Constants for the regression equation fitted to the species and depth data are given in the last three columns
