The northern gannet (Morus bassanus) is a seabird and the largest member of the gannet family, Sulidae. "Gannet" is derived from Old English ganot "strong or masculine", ultimately from the same Old Germanic root as "gander". Morus is derived from Ancient Greek moros, "foolish" due to the lack of fear shown by breeding gannets and boobies allowing them to be easily killed. The specific bassanus is from the Bass Rock in the Firth of Forth, which holds the world's largest colony of northern gannets.
