Boxed Up to Go by Adam Summers, naturalhistorymag.com: Scientists visualized the flow of water around a boxfish by placing neutrally buoyant beads in the water and filming the beads as they swept past plastic models of the fish. The drag coefficient of the boxfish is just 0.2, which is comparable to some streamlined airfoils, and falls well below 1.5, the drag coefficient of a flat-faced box. The edges of the bony box act as keels and passive stabilizers assisting the fish in diving and surfacing. The boxfish can swim as fast as 6 body lengths/second! #Boxfish #Biomechanics #naturalhistorymag #Adam_Summers
