Fig. 9. Drag coefficient versus crown angle for representative Chondrus at low to intermediate water velocities (0.2 to 1.0 m s^–1). Reconfiguration was inversely related to crown angle such that maximal reconfiguration approaches 0°. The thin lines are linear regressions for each individual. The thick broken line was for a rigid cone of variable shape, where the cone's crown angle was equal to the angle of the peak of the cone (Hoerner, 1965). The angles above the x-axis represent cone of equal frontal area but spire angles of 30, 90 and 150°, respectively.
