Rostratus (masculine), rostrata (feminine) or rostratum (neuter) is a Latin adjective meaning "beaked, curved, hooked, with a crooked point, or with a curved front".
In marine warfare, the term beak (rostrum) referred to the ram bows on warships, which were metal or metal-covered beams projecting from ships' bows, used to pierce enemy vessels by ramming.
