Curvature Helps Stiffen Fish Fins (video) Brown University Share Print E-Mail Loading video... Caption New research shows how the architecture of fish fins combines the bending strength of bones with the elastic resistance of the membrane that lashes them together, making the fin stiffer. The way in which this architecture transmits forces is broadly similar to the way in which forces are transmitted in a slice of pizza that is curved at the crust and becomes more rigid along its length.
