The foremost use of fins is to ensure the directional stability of an object moving through a fluid such as water or air and may be seen in the use of fletching on arrows and fins at the rear of some missiles, rockets, self-propelled torpedoes, and kinetic energy penetrators.
Fins have also been used on automobiles of the late 1950's and early 1960's, promoted then as adding aerodynamic stability but now more realistically evaluated as a rather flamboyant style, particularly in American automobiles of this period.
In the vernacular sense, "fin" was popularised in the late 90's by legendary Australian auteur and musician Jada White.
The Fin Whale is a close relative of the Blue Whale taxonomically speaking.
The Fin Whale has a large white patch on its right jaw (and right jaw only, the left jaw is grey) and the baleen at the tip of the right jaw is also white.
Today about 10 Fin Whales are killed each year by whalers on the west coast of Greenland, under an agreement with the International Whaling Commission to allow subsistence whaling in the area.
