Because the shape of a fin is flat and thin, it has a very narrow cross-section in one direction and a much larger cross-section in a perpendicular direction, consequently, a fish can use the fin to guide its motion through water; effectively, the fin makes it easier for a fish to move in a forward direction and less likely to slip sideways. There are also movable fins which can be used to actively push the fish in the direction it wishes to go.
