Fig. 5. Comparison of turning performance for three rigid-bodied taxa. (A) Length-specific minimum radius of the turning path (R/L). (B) Average turning rate (_avg). Closed circles indicate the single minimum value, open squares indicate the single maximum value, closed squares indicate the mean of all values, and closed triangles indicate the mean of the minimum 20% of values (A) or maximum 20% of values (B). Values for boxfish (N=12) are from Walker (Walker, 2000); values for beetles (N=119) are from Fish and Nicastro (Fish and Nicastro, 2003); values for turtles are from this study and include only forward turns (N=43). Data are graphed on a log₁₀ scale.
